 | Paleontologists announced the discovery of a dinosaur-like animal living 10 million years earlier than the oldest known dinosaurs. The researchers suggest that dinosaurs and other close relatives might have also lived much earlier than previously thought. The description of the new species Asilisaurus kongwe appears in the March 4 issue of the journal Nature in a paper lead-authored by Sterling Nesbitt, a University of Texas at Austin postdoctoral researcher. ...> Full Article |
 | Sixty-seven million years ago, when dinosaur hatchlings first scrambled out of their eggs, their first -- and last -- glimpse of the world might have been the open jaws of a 3.5-meter-long snake named Sanajeh indicus, based on the discovery in India of a nearly complete fossilized skeleton of a primitive snake coiled inside a dinosaur nest. ...> Full Article |
A new study just published in the Proceedings of the National Academy of Sciences provides yet more evidence that birds did not descend from ground-dwelling theropod dinosaurs, experts say, and continues to challenge decades of accepted theories about the evolution of flight.

A 60-million-year-old relative of crocodiles described this week by University of Florida researchers in the Journal of Vertebrate Paleontology was likely a food source for Titanoboa, the largest snake the world has ever known.

 | Fossils of five ancient crocs, including one with teeth like boar tusks and another with a snout like a duck's bill, have been discovered in the Sahara by National Geographic Explorer-in-Residence Paul Sereno. The five crocs, three of them newly named species, were part of the bizarre world of crocs that inhabited the southern land mass known as Gondwana some 100 million years ago. ...> Full Article |
 | Discovered by scientists at the University of Leicester and the Geological Institute, Beijing, Darwin's pterodactyl preyed on flying dinosaurs and shows how a controversial type of evolution may have powered the origin of major new groups. ...> Full Article |
The world's largest living lizard species, the Komodo dragon (Varanus komodoensis), is vulnerable to extinction and yet little is known about its natural history. New research by a team of palaeontologists and archaeologists from Australia, Malaysia and Indonesia, who studied fossil evidence from Australia, Timor, Flores, Java and India, shows that Komodo Dragons most likely evolved in Australia and dispersed westward to Indonesia.

Montana State University researchers recently took a 75-million-year-old turtle for a CT scan to look for its skull, additional eggs and possible embryos.

Scientists have recovered fossils from a 60-million-year-old South American snake whose length and weight might make today's anacondas and reticulated pythons seem a bit cuter and more cuddly. Named Titanoboa cerrejonensis by its discoverers, the size of the snake's vertebrae suggest it weighed 1,140 kilograms (2,500 pounds) and measured 13 meters (42.7 feet) nose to tail tip -- and that's a conservative estimate. A report describing the find appears in this week's Nature.

 | In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle.The find strongly suggests that animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean. ...> Full Article |
Since the age of dinosaurs, turtles have looked pretty much as they do now with their shells intact, and scientists lacked conclusive evidence to support competing evolutionary theories. Now with the discovery in China of the oldest known turtle fossil, estimated at 220 million years old, scientists have a clearer picture of how the turtle got its shell.

Long before tourists arrived in the Bahamas, ancient visitors took up residence in this archipelago off Florida's coast and left remains offering stark evidence that the arrival of humans can permanently change - and eliminate - life on what had been isolated islands, says a University of Florida researcher.
