TOP TEN DINOSAUR & FOSSIL FINDS:

Most Read of 2008

December 19, 2008

Bizarre prehistoric creatures—sea monsters, gargantuan rodents, a redheaded Neanderthal—are among the stars of the most read stories on dinosaurs and fossils covered by National Geographic News in 2008.

 

  10. “Amazing” Dinosaur Trove Discovered in Utah
Two meat-eating dinosaurs, a probable Stegosaurus, and four sauropods quickly emerged at a dig that found a “logjam” of fossils, scientists announced in June.
  9. Odd Fish Find Contradicts Intelligent-Design Argument
Flatfishes’ lopsided eye arrangement evolved gradually, a July fossil study suggested—perhaps solving “a major, major puzzle to evolutionary biologists.”

 

  8. PHOTO IN THE NEWS: DNA-Based Neanderthal Face Unveiled
Redheaded like her Flintstones namesake, Wilma—the first recreation of a Neanderthal based on DNA evidence—made her debut in September.

 

  7. “Bizarre” New Dinosaur: Giant Raptor Found in Argentina
An “unexpected,” 20-foot-long new dinosaur was discovered in South America, rewriting the evolutionary history of raptors, a December study said.

 

  6. PHOTO IN THE NEWS: New “Sea Monster” Species Identified
The new genus of dinosaur-era, carnivorous reptile, found deep in a Canadian mine, is also one of the most complete fossils of its kind ever unearthed.

 

  5. Giant “Sea Monster” Fossil Discovered in Arctic
Described as “the T. rex of the ocean,” the dinosaur-era predator is one of the largest marine reptiles ever found, scientists announced in February. ALSO SEE: pictures of the sea monster.

 

  4. PHOTOS: Bizarre New Dinosaurs Found in Sahara
Two new species of two-legged carnivores were unveiled in February: one that hunted like a shark and another that may have eaten like a hyena, researchers said. ALSO SEE: full story of the Sahara dinosaurs.

 

  3. Bull-Size Rodent Discovered—Biggest Yet
The prehistoric “rat” had huge teeth, a January study said. The animal likely competed with saber-toothed cats and giant, flightless, meat-eating birds. ALSO SEE: pictures of the giant rodent.

 

  2. Giant “Frog From Hell” Fossil Found in Madagascar
Scientists working in Madagascar found in February what may be the largest frog that ever lived—and it had an attitude to match.

 

  1. Ancient Praying Mantis Found in Amber
An 87-million-year-old insect from Japan could be a “missing link” between mantises from dinosaur times and the modern-day bugs, researchers said in April.

2008-11-12 – Mario De Stefano e Diatomee premiati allo «Science and Engineering Visualization Challenge 2008»

Congratulazioni a Mario De Stefano (..e alle Diatomee …) vincitore del:

«Science and Engineering Visualization Challenge 2008»

Scienza, le foto più belle del 2008

Microalghe come opere d’arte e ventose di seppia che sembrano mostri. Tra i premiati anche un italiano

 

MILANO – Viene definito il «linguaggio visivo nella comunicazione scientifica»: anche quest’anno la rivista specializzata Science e la National Science Foundation (NSF) hanno premiato la migliore foto nella competizione internazionale «Science and Engineering Visualization Challenge 2008». Sono in assoluto tra i migliori prodotti al mondo di scienziati, ingegneri, specialisti nella comunicazione visiva ed artisti che hanno utilizzato in maniera innovativa i mezzi visivi, foto e filmati, per promuovere la comprensione dei risultati della ricerca e dei fenomeni scientifici. Insomma, delle vere e proprie opere d’arte dalla natura con l’aiuto dei più moderni mezzi tecnologici. È il punto d’unione tra la letteratura scientifica e i comuni cittadini: le illustrazioni. Fili oscillati; ventose pungenti; il libro della Bibbia in un’immagine; numerosi sono anche stavolta i soggetti premiati nelle varie categorie.

DIATOMEE – Nella categoria “Fotografia” ha vinto quest’anno Mario De Stefano, del Dipartimentio Scienze Ambientali alla Seconda Università di Napoli. La sua foto The Glass Forest mostra delle diatomee, microalghe unicellulari, comparse circa 135 milioni di anni fa, che con le loro forme bizzarre ispirarono già gli studi pittorici dello scienziato tedesco Ernst Haeckel quasi 140 anni fa. Lo scatto col microscopio elettronico a scansione mostra delle Licmophora ehrenbergii, una specie marina presente nel Mediterraneo. Le sue cellule (verdi) triangolari raggiungono i 30 micrometri, ovvero quasi esattamente un milionesimo di metro. Per i ricercatori si sono rilevati dei materiali naturali ottimali per applicazioni nel campo della micro e nano fotonica. Le strutture colorate di marrone sono invece dell’idrozoo Eudendrium racemosum, caraterizzato dalla sua forma di polipo. Il titolo della foto premiata fa riferimento al fatto che queste alghe usano dei composti di silicio per la costruzione dei loro astucci. Le oltre 100 mila specie di diatomee conosciute sono di grande importanza in acque dolci e salate, in quanto la loro massa ingente permette l’ossigenazione di questi ambienti, consentendo lo sviluppo della vita animale aerobica: producono il 40 per cento dell’ossigeno nell’atmosfera.

First Place, Photography: “The Glass Forest”

September 25, 2008–Tiny green diatoms create the illusion of a fernlike forest as they attach to their marine-invertebrate hosts.

Mario De Stefano of the Second University of Naples, Italy, captured this miniscule “jungle” from the Mediterranean Sea with a scanning electron microscope.

The image earned first place in the photography category of the 2008 International Science and Engineering Visualization Challenge.

The awards are given annually by the National Science Foundation and the journal Science for images that employ modern technology to visualize complex scientific topics. (See some of last year’s winners.)

The winners will be announced in tomorrow’s issue of Science.

2008-10-08 – Nuovo mercato dei fossili negli USA (25th Annual South Carolina Fossil Fair)

25th Annual South Carolina Fossil Fair

Fun, Hands-on, Educational Event for Science, History and your family!

Myrtle Beach, SC (Vocus/PRWEB ) October 8, 2008 — Ocean Lakes Family Campground is hosting the 25th Annual South Carolina Fossil Fair presented by the South Carolina Fossil Association on Saturday, October 25, 2008 from 9 AM to 3 PM in the Recreation Building. The Fossil Fair is a free, family fun event open to the public. Experts from the Smithsonian Institution’s National Museum of Natural History will be at Ocean Lakes for free fossil identification. Museum Specialists from the Department of Paleobiology include Robert W. Purdy, Museum Specialist, specializes in Fossil Fish; David J. Bohaska, Museum Specialist, specializes in Fossil Whales; Frederick V. Grady, Museum Specialist, specializes in Pleistocene Mammals; and Erich Fitzgerald, on Post Doctoral Fellowship with the Smithsonian, specializes in Fossil Whales. The Fair is a great opportunity to speak with experts from the Smithsonian, collectors, and to learn about this educational hobby and the history of the Southeast. “October is a great time to hold a Fossil Fair. The weather is great and Halloween makes everyone think of skeletons and old bones,” comments Barb Krumm, Marketing Director for Ocean Lakes. “It’s proved to be a great resource for science projects, home schoolers, and scout troops.”

Fossil collections will be on display by members of the Myrtle Beach Fossil Club and regional collectors. The displays feature fossils such as whale bones, sand dollars, horse teeth, shark teeth, mastodon teeth and other fossils from the Southeast. There will be shell collections on display at Ocean Lakes Nature Center Discovery Lab. Tour the Nature Center with Ocean Lakes Curator, Leonard Raker, to see more than 10,000 shells and fossils.

The Fossil Fair includes several hands-on activities for kids of all ages. Participants can learn how to recover fossils from the field with Smithsonian experts at our “mock dig site” on Ocean Lakes’ beachfront at 11 AM and 2 PM (weather permitting). Visitors will have the opportunity to hunt for shark teeth in material from PCS Phosphate Mine from Aurora, NC. Then they can create their own shark’s tooth necklace with beads and materials supplied by Ocean Lakes and PCS Phosphate Mine.

Collectors interested in displaying at this year’s show please contact Kris Ziegler or Barb Krumm at (843) 828-4833 or email: info @ oceanlakes.com. Admission is free and open to the public. Call Ocean Lakes for reservations and to reserve a campsite by dialing 1-800-722-1451, and no need for a hotel, rent one of our 300 rental houses, dial 1-800-845-2229. Ocean Lakes Family Campground’s Recreation Building is located at 6001 South Kings Hwy, Myrtle Beach, SC 29575 (only 160 feet from the Atlantic Ocean).

MEDIA CONTACT: Barb Krumm, Director of Marketing and Public Relations (Ocean Lakes), please call (843) 828-4829 or (843) 457-0601 cell.
