2009-03-01 – Perù: fossile di uccello gigante (Giant fossil bird)

Perù: paleontologia, trovato fossile uccello di 10mln di anni

Sabato 28 febbraio 2009 02.25
Il fossile di un gigantesco uccello vissuto circa 10 milioni di anni fa è stato ritrovato nella regione di Ocucaje, nel Perù meridionale. Mario Urbina, paleontologo nel Museo nazionale di storia naturale, ha detto che il volatile sembra appartenere ai pelagornitidi, una specie comparsa circa 50 milioni di anni fa e estinta 2,5 milioni di anni fa a causa dei cambiamenti climatici. Questo tipo di uccello aveva un’apertura alare di oltre sei metri, nidificava in prossimità delle coste e si cibava dei pesci che riusciva a catturare tuffandosi nel Pacifico. Nel corso di scavi in corso nella regione, alcuni ricercatori hanno ritrovato la testa fossile dell’uccello, lunga circa 40 centimetri. Oltre alla considerevole apertura alare, una delle caratteristiche più curiose di questa specie è la presenza di denti all’estremità del becco.

Fossil skull of giant toothy seabird found in Peru

LIMA, Peru (AP) — The unusually intact fossilized skull of a giant, bony-toothed seabird that lived up to 10 million years ago was found on Peru’s arid southern coast, researchers said Friday.

The fossil is the best-preserved cranium ever found of a pelagornithid, a family of large seabirds believed to have gone extinct some 3 million years ago, said Rodolfo Salas, head of vertebrate paleontology at Peru’s National History Museum.

The museum said in a statement that the birds had wingspans of up to 20 feet (6 meters) and may have used the toothlike projections on their beaks to prey on slippery fish and squid. But studying members of the Pelagornithidae family has been difficult because their extremely thin bones — while helpful for keeping the avian giants aloft — tended not to survive as fossils.

“Its fossils are very strange, very rare and very hard to find,” Salas told The Associated Press.

The cranium discovered in Peru is 16 inches (40 centimeters) long and is believed to be 8 million to 10 million years old, based on the age of the rock bed in which it was found.

“Rarely are any bones of these gigantic, marine birds found fossilized uncrushed, and to find an uncrushed skull of this size is very significant,” said Ken Campbell, curator of vertebrate zoology at the Natural History Museum of Los Angeles.

Campbell, who examined photos of the find but was not involved in the dig, said he knows of “no specimen of comparable quality.”

Dan Kepska, a paleontology researcher at North Carolina State University who also was not part of the project, agreed that the skull is the most complete ever reported.

He called the birds “one of the great enigmas of avian paleontology.”

With fossils discovered in North America, North Africa and even Antarctica, Kepska said, the birds were ubiquitous only a few million years before humans evolved and scientists puzzle over why they died out. Some believe they are related to gannets and pelicans, while other say they are related to ducks.

Campbell said the Peru find “will undoubtedly be of great importance to our understanding of these gigantic birds, and it will help clarify the relationships of the other fossil pelagornithids found in the Pisco Formation.”

The formation, a coastal rock bed south of the capital, Lima, is known for yielding fossils of whales, dolphins, turtles and other marine life dating as far back as 14 million years.

2009-02-05 – Maiacetus inuus (Archaeoceti) e l’origine delle balene (whales origin)

Antiche balene di terra

Scoperti fossili di un antenato delle odierne balene che conduceva parte della vita in terra e parte in acqua

Due nuovi fossili di antiche balene – una femmina gravida e un maschio – gettano luce sul modo in cui gli antenati di questi giganteschi mammiferi sono passati da una vita terricola a quella acquatica.

I fossili risalgono a 47,5 milioni di anni fa e sono stati scoperti in Pakistan fra il 2000 e il 2004 per essere quindi studiati da paleontologi dell’Università del Michigan, che ora illustrano i loro risultati in un articolo pubblicato sulla rivista on line PloS.

Rispetto agli altri fossili di balena, quelli esaminati da Philip Gingerich e collaboratori – appartenenti alla specie Maiacetus inuus, facente parte del gruppo degli Archaeoceti – occupano una posizione intermedia sul cammino evolutivo che le ha portate a passare dall’essere animali completamente terricoli a marini.

L’eccezionalità del ritrovamento è dovuto anche al fatto che è la prima volta che si trova lo scheletro completo del feto di uno di questi animali. Il feto è posizionato in posizione cefalica, come i mammiferi terrestri e a differenza delle attuali balene, e ciò indica – osservano i ricercatori - che queste antiche balene partorivano sulla terraferma e non in mare. Un altro indizio dello stile di vita terricolo di questi animali è dato dal gruppo di denti ben sviluppati chiaramente individuabili nel fossile del feto, che indicano la capacità del piccolo di iniziare ad alimentarsi da solo.

Maiacetus aveva quattro zampe modificate in modo da poter nuotare abbastanza agevolmente. Peraltro, per quanto i loro arti modificati fossero in grado di sopportare il peso del corpo anche sulla terra, con molta probabilità non mettevano in grado l’animale di percorrere distanze di una certa entità. “Chiaramente vivevano nella zona compresa fra l’acqua e la terra andando su e giù”, ha osservato Gingerich.

Da altri indizi anatomici, fra cui la differenza di lunghezza dei canini fra maschio e femmina, i ricercatori hanno anche potuto ipotizzare, sulla scorta di un raffronto con i comportamenti delle diverse specie attualmente viventi, che i maschi non avessero una comportamento territoriale né che fossero a capo di un branco di femmine.  (gg)

Pregnant fossil shows how early whales evolved

Wed Feb 4, 2009 1:33am GMT

CHICAGO (Reuters) – Fossils from two early whales — a male and a rare pregnant female — shed light on how these ancestors to modern whales made the leap from walking on land to ruling the sea.

 The fetal remains, found with the 47.5 million-year-old pregnant female, were positioned head down, suggesting these creatures gave birth on land, while spending much of the rest of their time in the water.

 Initially, the tiny fetal teeth stumped University of Michigan paleontologist Philip Gingerich, whose team discovered the fossils in Pakistan in 2000 and 2004.

 “When I first saw the small teeth in the field, I thought we were dealing with a small adult whale, but then we continued to expose the specimen and found ribs that seemed too large to go with those teeth,” Gingerich, whose study appears in the Public Library of Science journal PLoS ONE.

 The fetal skeleton is the first specimen of the extinct whale group known as Archaeoceti, and the find represents a new species named Maiacetus inuus, a hybrid of the words for “mother whale” and Inuus, the name of a Roman fertility god.

 The fetus was positioned head down like other land animals, allowing it to begin breathing right away. This suggests the group had not yet made the leap to giving birth in the water like modern whales, which are born tail first to allow them to start swimming right after birth.

 The 8.5-foot (2.59-meter) male, which was collected in the same fossil beds as the female, is about 12 percent bigger and had fangs that were 20 percent larger than those of the female. Gingerich said these well developed choppers suggest the creatures spent a large portion of their time catching and eating fish.

 Both fossils had four flipper-like legs that could have supported their weight on land, but only for short distances, suggesting these whales likely came on shore to mate, rest and give birth, Gingerich said.

 “They clearly were tied to shore,” Gingerich said. “They were living at the land-sea interface and going back and forth.”

He said the Maiacetus fossils appear to represent an intermediate whale form, showing the evolution from land-dwelling to aquatic creatures.

2009-01-25 – Burgess Shale fossils at the Royal Ontario Museum

‘A Fossil Paradise’ At Royal Ontario Museum

One hundred years ago a discovery was made that drastically changed our view of the history of life on Earth. The Royal Ontario Museum (ROM) presents A Fossil Paradise: The Discovery of the Burgess Shale by Charles D. Walcott, an exploration of the Burgess Shale’s early excavations, including vintage panoramic photos, site artifacts and a profile of the man who made the great discovery as told by his personal field notes and letters.

Considered one of the most important finds in palaeontology, the Burgess Shale was humankind’s first view into some of the most ancient and bizarre animals to inhabit our planet 500 million years ago. From January 31, 2009 to April 26, 2009, the exhibition will be presented on Level 2 of the Hilary and Galen Weston Wing, next to a display of fossils from the ROM’s own storerooms, the largest and most diverse collection of Burgess Shale specimens in the world.

“The origin of today’s animal diversity can be traced back to half-billion years in the superbly preserved fossils of the Burgess Shale,” said Jean-Bernard Caron, Associate Curator, Invertebrate Palaeontology. “The period when these animals lived shortly followed a time of massive evolutionary changes and experimentations, known as the Cambrian Explosion. Today, these fossils continue to marvel scientists and public alike in providing important clues on this unique chapter in the history of life.”

The Burgess Shale is located in the UNESCO World Heritage Canadian Rocky Mountain Parks, near the town of Field, British Columbia. The spot contains some of the world’s most spectacularly preserved fossilized remains of soft-bodied organisms that evolved in the Cambrian Period, 500 million years ago. Concealed within layers of rock are fine details of their anatomy, allowing a greater understanding of the ecology, diversity and evolution of animal communities during that period. American Charles Doolittle Walcott (1850-1927), discovered the most important of the Burgess Shale sites in 1909 while serving as the Fourth Secretary of the Smithsonian Institution in Washington, D.C., and regularly returned to the Burgess Shale until 1924 when, at the age of 74, he had collected over 65,000 specimens.

Vintage Photography

Walcott used photography to document his scientific work. While this was an important means of documenting scientific findings, field photography in the early 1900s was extremely cumbersome. Walcott preferred glass-plate negatives, which meant hauling heavy glass over the mountains by horse. It was also often necessary to send test photo shots all the way to Washington, D.C. to be developed and back before he knew whether to adjust the camera. Despite these hardships, by the time of his last expedition, Walcott had taken 650 photographic panoramas of the Canadian Rockies.

A Fossil Paradise includes eight of these oversize vintage panoramic photographs that demonstrate the scenic grandeur of the area and document a geologist at work in the early 20th century. Also on display is a 2.5 metre (over 8 feet) wide panorama taken from Burgess Pass by Walcott in 1911, the largest photograph ever published by National Geographic. Visitors can also see a circa 1908 R.B. Cirkut camera of the type used by Walcott. — www.rom.on.ca

2009-01-24 – Messico: sequestro di fossili (Mexico, Fossils seized)

Mexico Seizes Largest Batch of Fossils

MONTERREY, MEXICO — Mexican authorities revealed that they recovered 389 fossiles, among which are the remains of dinosaurs and trilobites hundreds of millions of years old, that were illegally being offered for sale at an antiquities store in the northern state of Nuevo Leon.

The director of the Monterrey office of the National Anthropology and History Institute, or INAH, Hector Jaime Treviño, as well as Joaquin Garcia-Barcenas, the president of the INAH Paleontologists Council, said that this is the most important confiscation to date in Mexico that includes unique fossils.

They emphasized that no museum in Mexico has more than 200 pieces of this kind and this collection contains almost double that number, a group that should be sufficient to mount two simultaneous exhibits.

Both officials said that the pieces were recovered in a operation in 2006 by the Attorney General’s Office from a shop in the Monterrey suburb of San Pedro Garza Garcia.

They said that the work of registering, cataloguing and authentificating the pieces had taken three years and was only being publicly announced Thursday.

The case began in 2005, when an individual asked INAH for information about the authenticity of a fossil more than 350 million years old he had bought at the store near Monterrey.

INAH experts confirmed that the fossils were authentic and complained to the AG’s office about the illegal selling of the ancient items.

Among the pieces confiscated are remains of mammoths, camels, early horses, sharks, mastodons, various dinosaurs, ammonites (giant marine mollusks that lived about 100 million years ago) and trilobites, which were large underwater pillbug-like creatures that were one of the planet’s dominant life forms 350 million years ago.

Also among the pieces are fossils of fish, pieces of amber and other rare items.

Paleontologist Garcia-Barcena said that the fossils provided much-needed information about climatic and evolutionary changes in the region, adding that “for example, it was determined that there was an ocean where today there are plains.”

INAH announced that it will send an exhibition of the trove of fossils around the country so that the public can view the items. EFE

2009-01-23 – Liaoning, Cina: un nuovo Pterosauro (Pterosaur Fossil)

Dal Cretaceo di Liaoning (Cina) l’ennesimo ritrovamento spettacolare: un piccolo pterosauro caratterizzato da un’ampiezza alare di soli 25 centimetri circa e da un becco appuntito e privo di denti.

—————————————————

Pterosaur Fossil With 10 Inch Wingspan Discovered

With a wingspan of only 10 inches, this weird fossil is one of the world’s smallest species of flying Pterosaurs.

pterosaur Pterosaur Fossil With 10 Inch Wingspan Discovered picture

It was recently discovered in the western part of China’s Liaoning Province, which is believed to have been a forested area during the early Cretaceous Period some 120 million years ago.

This pterosaur was equivalent to the size of a modern blackbird.

“The fossil is very well preserved and it has long sharp bill. It was toothless and its skull was just over 4cm (more than 1-inch) long.” said Wang Xiaolin of the Chinese Academy of Sciences.

Despite its small stature and wingspan, this small toothless reptile may well be the ancestor of gigantic Pterodactyls whose wing tips stretched 20-feet from wingtip to wingtip. This new species has been christened Nemicolopterus crypticus, meaning “hidden flying forest dweller”.

The slight shiver that might be crawling up your back is a reminder that in its own way that this fossil is a connection to all living things, humans included.

2008-12-13 – Monte San Giorgio candidato per l’Unesco

Varese - Presentato dall’assessore alle Culture, identità e autonomie della Lombardia, Massimo Zanello
Monte San Giorgio candidato per l’Unesco


L’assessore alle Culture, identità e autonomie della Lombardia, Massimo Zanello, ha presentato oggi la candidatura del sito paleontologico di Monte San Giorgio per l’inserimento nella lista del Patrimonio mondiale dell’Unesco. «Il riconoscimento c’è già per l’area compresa nel versante svizzero – ha ricordato l’assessore regionale – e ora dobbiamo completare il procedimento, dato che il termine per la presentazione della candidatura scade il 1° febbraio prossimo».
L’accordo, sottoscritto con Ministero dei Beni e le attività culturali, Provincia e Camera di Commercio di Varese, Università di Milano (Dipartimento di Scienze della Terra “Ardito Desio”), Comuni di Besano, Clivio, Porto Ceresio, Saltrio, Viggiù e Comunità montana della Valceresio, riguarda la definizione delle metodologie di redazione e attuazione del piano di gestione del sito, caratterizzato dalla presenza di 30 specie di rettili e quasi 100 specie di pesci fossili, «punto di riferimento – ha sottolineato Andrea Tintori, docente di paleontologia all’Università di Milano – di altri ritrovamenti recenti avvenuti nella Cina meridionale, dove stanno venendo alla luce molti siti più o meno coevi ai nostri livelli fossiliferi».
L’area proposta per l’iscrizione, nella quale è collocato il giacimento fossilifero di eccezionale valore, è situata nella Provincia di Varese, nel territorio del Monte San Giorgio – Monte Pravello -  Monte Orsa, affacciato sul lago di Lugano. Dal 1972 l’Unesco (Agenzia delle Nazioni Unite il cui scopo è la promozione delle attività di educazione e diffusione della scienza e la cultura) ha istituito la Whl – World Heritage List, un elenco che comprende tutti i siti che per le loro straordinarie caratteristiche culturali e naturali vengono riconosciuti come “patrimonio culturale dell’umanità”.
Le aree comprese nella lista – che viene aggiornata annualmente – sono oggetto di particolari cure per la loro conservazione e valorizzazione, finalizzate alla loro trasmissione alle generazioni future. Il primo sito italiano cui è stato riconosciuto l’inserimento nella lista è stato,  nel 1979, la Valle Camonica. A tutt’oggi sono 43 i siti italiani inseriti nell’elenco.
«Oggi – ha ricordato l’assessore Zanello – l’eccellente quadro lombardo viene ad essere impreziosito da questa nuova candidatura: il sito di Monte San Giorgio è la miglior prova di quella simbiosi culturale che favorisce lo scambio di idee e progetti nel rispetto della nobile tradizione regionale».
L’assessorato alle Culture, identità e autonomie sostiene e promuove la presentazione di nuove candidature nonché la diffusione delle conoscenze sul patrimonio relative ai luoghi già inseriti nella lista Unesco.
«L’impegno regionale in questo ambito – ha ricordato Zanello – cresce di anno in anno, anche in considerazione del fatto che ben 6 siti già  riconosciuti si trovano in Lombardia; con la presentazione della candidatura di Monte S. Giorgio, e con l’inserimento dei siti di Brescia e Castelseprio il loro numero salirà a 8, facendo della Lombardia la regione italiana con il maggior numero di siti Unesco».

2008-11-24 – Eileanchelys waldmani: la prima tartaruga acquatica ? (sea-turtle missing link)

Reperti fossili di un genere di tartaruga ritrovati nel Giurassico scozzese aiutalo a comprendere il passaggio da una vita terrestre ad una marina.

I reperti di Eileanchelys waldmani rappresentano infatti una foma di passaggio in quanto sebbene adattati alla vita acquatica (ritrovati in sedimenti di laguna assieme a squali e altri organismi marini) presentno caratteristiche del cranio tipiche di esemplari terresti.

Inoltre sono comunque molto somiglianti a un genere attuale a prova della “bontà” del progetto evolutivo delle tartarughe acquatiche.

Scottish turtle is missing link

Monday, 24 November 2008
Cosmos Online

LONDON: Turtles normally evoke images of tropical seas, but palaeontologists have found the 164-million-year-old remains of one of the first known water-dwelling turtles on a chilly Scottish island.

These unique fossils bridge what has been a 65-million-year gap in the fossil record primitive land-based turtles and modern turtles, many of which live in the open ocean, said Jérémy Anquetin, based at both University College London (UCL) and the Natural History Museum, in England.

Rugged an beautiful

Against the rugged and beautiful backdrop of the Isle of Skye, his team have unearthed six fossils of a species called Eileanchelys waldmani. The discoveries are described in the British journal the Proceedings of the Royal Society B.

Similar fossils from the Middle Jurassic have been found in the U.S., Argentina, and Russia, but Anquetin’s are the most complete yet discovered and offer new clues about the tricky transition from land to water.

Though it seems an unlikely place to find tropical animals today, “Scotland was much farther south [in the Jurassic]… its position would not have been tropical, but its climate may have been,” said Anquetin.

These turtles would have shared their lagoon and lake environment with sharks and salamanders, whose remains have also been found at the site, he said.

Remarkable similarities

Despite the antiquity of the fossils, the species have some remarkably similar features to turtles found today, particularly a primitive freshwater species called the red-eared slider, found in the southeast of the U.S. and Mexico.

One major difference is that the skull of the fossil is more “reptilian” than modern turtles, said Anquetin. However, the overall body shape, or morphology of these turtles has changed very little over million of years, especially when compared with the transformations seen in mammals.

“I like to think [turtles] are an evolutionary success … because their body plan is still working,” said Anquetin, who added that (like crocodiles) they have outlived many catastrophes including numerous ice ages and mass extinctions.

The exciting research is helping plug a 65 million year gap in the fossil record, commented Walter Joyce a vertebrate palaeontologist and fossil turtle expert at the University of Tuebingen in Germany.

“The new fossil is finally giving us a glimpse of how early turtles evolved,” he said. “The authors make a compelling case that by this stage in evolution turtles had started moving into aquatic habitats.”

Scientific article:

Jérémy Anquetin, Paul M. Barrett, Marc E.H. Jones, Scott Moore-Fay and Susan E. Evans
Abstract

 The discovery of a new stem turtle from the Middle Jurassic (Bathonian) deposits of the Isle of Skye, Scotland, sheds new light on the early evolutionary history of Testudinata. Eileanchelys waldmani gen. et sp. nov. is known from cranial and postcranial material of several individuals and represents the most complete Middle Jurassic turtle described to date, bridging the morphological gap between basal turtles from the Late Triassic–Early Jurassic and crown-group turtles that diversify during the Late Jurassic. A phylogenetic analysis places the new taxon within the stem group of Testudines (crown-group turtles) and suggests a sister-group relationship between E. waldmani and Heckerochelys romani from the Middle Jurassic of Russia. Moreover, E. waldmani also demonstrates that stem turtles were ecologically diverse, as it may represent the earliest known aquatic turtle.

2008-11-20 – South Korea – Thailandia: continua la battaglia dei fossili (a new “bones war”)

Talks start with South Korea to retrieve stolen dinosaur fossils

BAMRUNG AMNATCHAROENRIT

Authorities are refusing to pay two billion baht to a South Korean businessman for the return of 130-million-year-old dinosaur fossils smuggled out of the country five years ago.

However, the Mineral Resources Department, East Asian Affairs Department, Customs Department and the Royal Thai Police are in negotiations with the South Korean government to have the stolen fossils returned to Thailand.

Local media reported last week that Korean businessman Chin Jae-Hun and his lawyer recently contacted the Thai embassy in Seoul, offering to sell back 1,000 dinosaur fossils found in the Northeast five years ago for the princely sum of two billion baht.

The fossils come from six 130-million-year-old Phuwiangosauruses (Phu Wiang lizards) titanosaurs which roamed Thailand during the Cretaceous period and grew up to 30 metres long.

According to reports, Chin Jae-Hun said he purchased the fossils through an underground agency, but had originally thought they were remains of elephants or buffaloes. However, in 2006 he said he had the fossils examined by an expert in South Korea, who confirmed they were Phuwiangosaurus fossils.

The Korean businessman says that if Thai authorities don’t buy back the fossils, he will sell them to a Japanese businessmen with an interest in fossils.

Varavudh Suteethorn of the Bureau of Fossil Research and director of the Geological Museum said Thailand will not buy back the fossils, as this would be in breach of the international consensus set by the United Nations Educational, Scientific and Cultural Organisation (Unesco), which bans fossil trading worldwide.

“The consensus states that fossils discovered in the territory of a country rightfully belong to the country,” said Mr Varavudh. “They cannot be moved out of the country or put up for sale.”

Mr Varavudh said this is one of the biggest cases of fossil trafficking in Thailand’s history.

Thailand implemented the Ancient Monuments, Antiques and National Museums Act on Aug 9, which aims to eliminate trafficking in fossils. The act gives a general amnesty to fossil traffickers under the condition they return any stolen fossils.

“But not to buy them back,” said Mr Varavudh, who added that if South Korea had the fossil protection law it would be easier for Thailand to negotiate their return.

Those exporting rare fossils without permission face prison terms of up to seven years, or fines up to 700,000 baht, and those trading in fossils without a licence face one year in prison or a 100,000 baht fine. The illicit trade in dinosaur fossils has surged in recent years – they are often used in amulets for their supposed mystical powers.
