2008-10-17 – Corea del Sud: 5 paleo-siti potrebbero entrare a far parte della lista Unesco (South Korea, dinosaurs, geo-site)

In Corea del sud è cominciato l’iter che potrebbe portare 5 aree con resti di Dinosauri ad essere inserite nella lista dei luoghi “patrimonio dell’umanita” UNESCO:

Haenam: il primo luogo al mondo dove sono tate trovate insieme impronte di Pterosauri e Uccelli (e di numerosi artropodi).

Hwasun: 1.550 impronte incluse quelle appartenenti a ben 60 teropodi

Su un isola presso Yeosu: 3500 impronte di dinosauri compresa una pista appatenente a un ornitopode lunga 85 metri.

Goseong: maggior concentrazione di impronte al mondo (con un gruppo con imponte di 410 individui) e con abbondanza di impronte di sauropodi (139) e ornitopodi. 

Boseong: 200 uova di dinosauro con diametro variabile da 60 a 180 mm e appartenenti a Sauropodi e Ornitopodi’. Presenti pure ossa di dinosauri e ossa e uova di tartarughe.

‘Dinosaur Coast’  Seeks UNESCO Listing

A campaign has been started to have five areas of the southern coastline where thousands of dinosaur footprints are to be found listed on the U.N. Educational, Scientific and Cultural Organization (UNESCO) World Natural Heritage list.

The five are Haenam, Hwasun, Boseong, and Yeonsu in South Jeolla Province, and Goseong in South Gyeonsang Province.

If successful, the move will follow the 2007 listing of Jeju Island.

Haenam was the first place in the world where dinosaur, pterosaur and bird tracks were found together. It also has numerous large arthropod tracks. The 7.3-meter long tracks made by a flying reptile are visible at the center of the fossil site, which is listed as Natural Treasure No. 394.

In Hwasun, there are about 1,500 footprints, including those belonging to more than 60 theropods.
On an island off Yeosu are a total of 3,500 dinosaur footprints, including an 85-meter-long track made by an ornithopod. The large number of footprints is thought to show that the southwestern area was primarily covered with mesic forests.

Boseong has 200 fossilized eggs, ranging from 60 millimeters (mm) to 180 mms in diameter, from sauropods and ornithpods. Well-preserved dinosaur bones, and turtle bones and eggs are also at the site.

Goseong has the highest concentration of tracks in the world, including the footprints of 410 individuals in one group. It also has the most abundant ornithopod footprints as well as 139 sauropod footprints.

UNESCO is to start a field study there from Saturday.

Prof. Huh Min, from Chonnam National University and director of the Korea Dinosaur Research Center, is initiating the campaign. He stressed that having a natural heritage is somewhat different from having a cultural site. Korea has eight cultural sites, including old palaces.

“Unlike cultural sites featuring their comparative value to different cultures, the natural sites have to be the `only one’ valuable to the world. It has to be academically, culturally, and in every way the best in the world,” he said.

To receive the UNESCO Natural Heritage listing, support from local residents and the administrations is critical. The preparation committee has established safe and protective pathways for visitors as well as straightened roads to preclude any possible destruction of the sites. “We have streamlined the region,” Huh said.

Preparation has been underway for more than three years, and he expects UNESCO inspectors to recognize the value and importance of the “Korean Cretaceous Dinosaur Coast.”

“We have seen dinosaurs in Western movies such as Jurassic Park and picture books. But here, we also had flying reptiles, and all kinds of dinosaurs walking, drinking, laying eggs and living just like any other creature,” he said.

Huh was selected as one of the 100 top scientists in the world by the International Biographical Center of Cambridge, England, in 2005; one of the 2,000 Outstanding Scientists of the 21st Century by the same institution in 2003; and one of the Great Minds of the 21st Century by the American Biographical Institute; for his pioneering studies on dinosaurs.

2008-10-17 – Utah, Usa: Nuovo “cimitero di dinosauri” (“Dinosaur graveyard”, tracks, “Gnatalie”, Deltapodus)

Nel nuovo cimitero dei dinosauri nello Utah meridionale, studiato da Luis Chiappe, sorprendentemente vi sono impronte e resti fossili sia del Giurassico che del Cretaceo.

Tra i primi, datati intorno a 145 milioni di anni fa, vanno annoverati un nuovo sauropode chiamato informalmente “Gnatalie”, e impronte di Stegosauro finora rinvenute solo in Europa (Deltapodus).

Tra i resti del Cretaceo vi sono invece impronte di Sauropodi, Teropodi e Ornitopodi.

‘Dinosaur graveyard’ found in southeast Utah

A 150-million-year-old sauropod skeleton is the centerpiece of the finds from the Jurassic and Cretaceous periods, discovered by a Los Angeles team.
By Thomas H. Maugh II, Los Angeles Times Staff Writer
9:25 AM PDT, October 17, 2008
Los Angeles researchers have discovered a “dinosaur graveyard” in southeastern Utah that is yielding a wealth of fossilized animals and footprints from the Jurassic and Cretaceous periods.

The centerpiece of the new finds is the well-preserved skeleton of a 150-million-year-old sauropod — a long-necked herbivore — that researchers have named “Gnatalie” because the scientists were “eaten alive” by gnats while they were excavating it earlier this year.

The team has so far excavated only part of the fossilized skeleton, which they estimate to be about 50 feet long. “It’s big and takes a lot of time,” said paleontologist Luis Chiappe, director of the Dinosaur Institute and the Natural History Museum of Los Angeles County.

Gnatalie was found in the remains of what was once a big riverbed and is now a light-colored stratum on the face of an exposed cliff. Nearby in the bed were the disarticulated remains of other sauropods and meat-eating dinosaurs, including the five-foot-long femur of a brachiosaur.

On the ridgeline of the cliff, the team found a large number of footprints preserved in sandstone. Surprisingly, one set of prints from the Jurassic era, which ended about 145 million years ago, prints of a sauropod were found near tracks of carnivorous theropods and herbivorous ornithopods from the early Cretaceous period, which ended about 65 million years ago.

Most stunning of all, to Chiappe, were the three-toed prints of a European stegosaur, named  “Deltapodus tracks have never been found in North America,” he said.

Chiappe and his staff, led by Doug Goudreau and Aisling Farrell, expect to spend at least another decade excavating the site.

The finds will be the centerpiece of an exhibit at the Natural History Museum of Los Angeles County that will open in 2011, he said.

A renovation of the dinosaur exhibit is part of the museum’s $84-million project to restore and seismically strengthen its original 1913 Beaux-Arts-inspired building.

2008-10-17 – Voyager: la storia delle pietre di Ica 2 (Ica stones)

Visto il successo del precedente post (192 visite) vale la pena di approfondire un pò l’argomento.

Un intervento su Wikipedia (link) riassume bene il servizio andato in onda anche se per fortuna contrariamente a quanto riportato si andati ben lontani dal definire le pietre “originali” rimanendo molto più sul vago (per alcune sarebbe stata provato che le inisioni siano state fatte 90:000 anni fa, altre più recenti, altre ancora attuali).

Detto ciò vanno fatte alcune considerazioni:

a) In una precedente puntata andata in onda credo prima dell’Estate il servizio delle pietra di Ica terminava con le parole del conduttore che annunciava che gli abitanti del luogo avevano confessato ma dopo che loro avevano già completato il servizio che quindi avevano deciso di mandare in onda ugualmenete, e che quindi tutta la storia era una burla.

b) tutta la storia è decisamente un falso non solo perchè alcuni abitanti del luogo hanno confessato di averle fatte, ma anche perchè si è voluto mantenere il mistero su luogo del ritrovamento: qualsiasi idiota avesse la fortuna di fare una scoperta così senzazionale non avrebbe alcun interesse a nascondere informazioni che potrebbero avvalorarne l’impotanza: gli introiti tra vendite di oggetti, premi statali, interviste e turismo sarebbero un più che valido sprone a cerare di fare quanta più chiarezza possibile.

c) si sostiene poi che le popolazioni locali non si siano mai arrichite, sarà vero ma non ne hanno mai avuto nessun bisogno nel senso che probabilmente non hanno mai avuto alcuna intezione di comprare ul monitor LCD o di fare una crociera, basta sopravivere; inoltre non è detto che sia una messa in scena “sociale”, potrebbe essere semplicemente opera di un ristretto gruppo di persone. E infine voi quanto paghereste per un oggetto che a voler essere buoni e falso al 99.999 % ????????

d) incongruenze paleontologiche: un gap di 60 milioni di anni è decisamente troppo sia per ipotizzare uomini viventi 60 milioni di anni fa, sia per ipotizzare popolazioni di dinosauri vissute fino a 90.000 anni fa (la data più antica a cui sono state fatte risalire le incisioni). Quantomeno opinabili le dichiarazioni di uno scienziato ameriano intervistato durante la trasmissone “ci sono numerose prove in tutto il mondo della coesistenza di uomini e dinoauri” si limita a pochi esempi tra cui un ricamo con degli animali molto più simili a un lupo che all’Allosauro di cui parla, e un incisione con una lucertola anch’essa spacciata per dinosauro (semplicemente ridicolo !!!!). Inoltre i dinosauri a voler guardare bene sono tutt’altro che ben fatti: sauropodi con placche ossee da Stegosauro o ancora dinosauri con “strutture circolari” sugli arti, dimostrano più il tentativo di un grossolana imitazione che una dettaglita ricostruzione: insomma non sono stati bravi nemmeno a copiare.

e) altre incongruenze: se anche uomini antichi avessero visto dei dinosauri !!!!!! ma cos potevano mai saperne di microscopi, cannocchiali e altre invenzioni tecnologiche: non sono stati nemmeno furbi a limitare la loro fantasia.

f) infine come ripotato sempre su Wikipedia anche le conlusioni del Cicap sconfessano l’originalità delle opere: I ricercatori del CICAP argomentano che in 40 anni ci sono 14.600 giorni, e che più di un campesino ha ammesso di averne fabbricate, ponendole poi in un gallinaio per dargli una patina d’antichità. Inoltre, sempre secondo il CICAP, la qualità e lo stile delle incisioni cambiano col tempo dei ritrovamenti. Ossia i dinosauri del 1966 sono fatti più approssimativamente di quelli recenti, e lo stesso fa il metodo di incisione: migliora col tempo dei ritrovamenti. Entrambi questi fatti sarebbero incompatibili col ritrovamento casuale di pezzi appartenenti ad un unico periodo storico.

Infine un piccolo appello: anche a me piace la trasmissione Voyager e la seguo sempre (anche se a volte le ipotesi mostrate sono quanto di più assurdo mai si possa pensare apparendo pertanto davvero ridicole) però trovo molto più bello e affascinante seguire programmi in cui si annunciano vere scoperte e dove gli interessi giornalistici non spingono a ipotizzare assurdità. Insomma continuate a vedere Voyager con mente aperta a tutto ma anche con occhio critico, ma io vi consiglio di guardare anche i programmi di Piero e Alberto Angela, di Mario Tozzi, Geo & Geo e il Tg Leonardo.

2008-10-17 – Colombia: Il più grande serpente fossile mai trovato (giant fossil snake)

Presentata al SVP Meeting la scoprta del più antico serpente fossile mai ritrovato.

Sono state scoperte in Colombia alcune vertebre (dieci centimetri di diametro, circa il doppio di quelle del più grande serpente attuale, l’Anaconda) e frammenti di costole di un serpente antenato dell’attuale Boa e risalenti a 60 milioni di anni fa. Grazie tali reperti si è stimato che l’esemplare completo doveva avere una lunghezza di 12,8 metri e un peso di 1,27 tonnellate

———————————————————

Fossil find may document largest snake

The ancient bonecrusher likely weighed more than a ton

CLEVELAND — Rocks beneath a coal mine in Colombia have yielded fossils of what could be the world’s largest snake, a relative of today’s boa constrictor that was 12.8 meters long and weighed more than a ton.

Few of today’s snakes exceed 9 meters in length, says Jonathan Bloch, a vertebrate paleontologist at the Florida Museum of Natural History at the University of Florida in Gainesville. Some of the snakes that lived about 60 million years ago, however, would have dwarfed their modern kin, he reported Wednesday in Cleveland at the annual meeting of the Society of Vertebrate Paleontology.

At a site in northern Colombia, Bloch and his colleagues unearthed the partial remains of an ancient snake. Each of the dozen or so vertebrae in that body segment measured about 10 centimeters across. That’s about twice the width of the largest vertebra taken from a 6-meter–long, modern-day anaconda, another modern relative, Bloch notes.

None of the ribs included in the fossil are complete, but the size and curvature of the fragments that remain indicate that the snake “would have had trouble fitting though the door into your office,” he adds. The gargantuan fossils represent an as yet unnamed species.

Estimating a snake’s length from fragmentary remains is difficult because most of the creature’s vertebrae differ only in their size, not in their proportions. Bloch and his colleagues can’t readily determine whether the segment that they unearthed came from the thickest portion of the snake, so their estimates of the snake’s size and weight are minimum values. The researchers contend that the ancient snake they discovered would have stretched at least 12.8 meters and weighed at least 1.27 metric tons.

Even one complete vertebra can enable scientists to make good estimates of a snake’s minimum length, says S. Blair Hedges, an evolutionary biologist at Penn State University in University Park. “This [snake] is definitely bigger than any modern-day snake,” he notes. The record length for a living species belongs to a reticulated python that measured 10 meters long.

The rocks that once entombed the snake remains had been laid down as clay-rich sediments on floodplains near a coastline about 60 million years ago, Bloch says. Other fossils excavated from the same layers include an aquatic turtle whose shell was 2 meters across and whose skull was the size of a dinner plate. So far, the paleontologists haven’t unearthed any mammal fossils at the site, so it’s a mystery as to what these creatures preyed upon.

2008-10-17: La verità sui molari di mammuth ritrovati dopo l’urgano Ike (Mammoth)

Si è scoperto che i molari di mammuth ritrovati qualche settimana fa dopo il passaggio dell uragano Ike provengono dalla collezione di uno studioso che tornato dall’evaquazione ha soperto di essere stato “rapinato dall’uragano” !!!

More to story of mammoth fossil found after Ike

By DIANA HEIDGERD Associated Press Writer © 2008 The Associated Press

Oct. 16, 2008, 4:35PM

An elephant expert whose Texas beach home was destroyed by Hurricane Ike is putting his collection back together — one tooth at a time.

Roy Davis evacuated his Bolivar Peninsula home on Sept. 11, two days before Ike slammed the Texas coast.

Davis, 57, said Thursday that among the items scattered out of his one-bedroom house were prized animal keepsakes from his years working at zoos.

“I probably had 30 pieces of modern-day elephants, they shed their teeth, they wear them down,” Davis said.

Two treasured elephant teeth have now been returned to Davis, after media reports about what appeared to be an unusual fossil find on the beach.

Davis says he lived a couple of doors down from Lamar University educator Dorothy Sisk, whose house in the community of Caplen also was destroyed by Ike.

Sisk and a Lamar colleague, paleontologist Jim Westgate, went to the area a few days after the Sept. 13 hurricane to see what was left of her place.

They came upon a 6-pound tooth that Westgate recognized as a fossil from a mammoth common to North America until around 10,000 years ago.

The second tooth, from an African elephant, was discovered Oct. 4 on the beach by a reporter doing a story on the original find.

Eventually, the teeth made it back to Davis after media accounts surfaced about a fossil possibly washing ashore.

Davis, superintendent of Lake Houston Park, is making his interim home in a travel trailer since Ike.

Davis has had the mammoth’s tooth since the mid-1980s when it turned up at a construction site in Tyler. At the time Davis was head elephant trainer at Caldwell Zoo.

Davis, a Moore, Okla., native, says the African elephant tooth came from when he was working at the Oklahoma City Zoo. An elephant named Timboo died in the 1970s.

“Since I was the only one that could handle the animal at the time, they gave it to me as a remembrance of the elephant,” he said.

As for the rest of his elephant items?

“They’re still somewhere on the beach down there,” Davis said. “None have shown up yet. They may. If they don’t, they turn up 10-15 years from now.”

Westgate was glad to return the mammoth fossil to Davis.

“All the houses in Caplen are no longer there. It’s kind of neat that he got something back after that total loss,” said Westgate.
