Starvation didn't wipe out saber-toothed cats

Saber-toothed cats apparently did not go extinct for lack of prey, contradicting a popular explanation for why they died off, fossil evidence now suggests.

 

'Alien-like' skulls unearthed in Mexico

Although cranial deformation and dental mutilation were common features among the pre-Hispanic populations of Mesoamerica and western Mexico, scientists had not previously seen either in Sonora or the American Southwest.

 

Dinosaur Cells In T. Rex Fossil? Shocking Find Gets New Support From Molecular Analysis

T-Rex

Twenty years ago, paleontologist Mary Schweitzer made an astonishing discovery. Peering through a microscope at a slice of dinosaur bone, she spotted what looked for all the world like red blood cells. It seemed utterly impossible—organic remains were not supposed to survive the fossilization process—but test after test indicated that the spherical structures were indeed red blood cells from a 67-million-year-old Tyrannosaurus rex. In the years that followed, she and her colleagues discovered other apparent soft tissues, including what seem to be blood vessels and feather fibers. But controversy accompanied their claims. Skeptics argued that the alleged organic tissues were instead biofilm—slime formed by microbes that invaded the fossilized bone.

 

First human ancestor looked like a squirrel

Newly discovered fossilized bones for the world's oldest and most primitive known primate, Purgatorius, reveal a tiny, agile animal that spent much of its time eating fruit and climbing trees, according to a study.

 

New, Bizarre Species of Small Dinosaur Identified

Dinosaur

Not every dinosaur grew up to be a mighty predator like Tyrannosaurus rex or a hulking vegan like Apatosaurus. A few stayed small, and some of the smallest dinosaurs that ever lived — tiny enough to nip at your heels — were among the first to spread across the planet more than 200 million years ago.

 

Prehistoric tiny bugs found trapped in amber

Scientists have found three well preserved ancient insects frozen in amber - and time - in what is Earth's oldest bug trap. The discoveries of amber-encased insects in Italy may sound like something out of "Jurassic Park" but these bugs are even older than that. They are about 230 million years old, which puts them in the Triassic time period, and about 100 million years older than what had been the previously known oldest critters trapped in fossilized tree resin, or amber.

 

New Fossils Indicate Offshoots in Human Family Tree

Meave Leakey and Fred Spoor

Fossil by fossil, scientists over the last 40 years have suspected that their models for the more immediate human family tree — the single trunk, straight as a Ponderosa pine, up from Homo habilis to Homo erectus to Homo sapiens — were oversimplified. The day for that serious revision may be at hand.

 

First Photos of China's 298-Million-Year-Old Buried Forest

Chinese Fossilized Forest

These are the first photos of some of the countless treasures found in the extraordinary 298-million-year-old forest discovered under coal mine in Wuda, Inner Mongolia, China.

 

UK scientists find 'lost' Darwin fossils

British scientists have found scores of fossils the great evolutionary theorist Charles Darwin and his peers collected but that had been lost for more than 150 years....

 

Life on Mars? Fossil find shows it's possible

Scientists have found Earth's oldest fossils in Australia and say their microscopic discovery is convincing evidence that cells and bacteria were able to thrive in an oxygen-free world more than 3.4 billion years ago.
