Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth.

Tyrannosaurus Rex And Mastodon Protein Fragments Discovered, Sequenced
Scientists have confirmed the existence of protein in soft tissue recovered from the fossil bones of a 68 million-year-old Tyrannosaurus rex (T. rex) and a half-million-year-old mastodon.

UCLA Scientists, Colleagues Substantiate Biological Origin Of Earliest Fossils
UCLA paleobiologist J. William Schopf and colleagues have substantiated the biological origin of the earliest known cellular fossils, which are 3.5 billion years old.

Oldest Complex Organic Molecules Found In Ancient Fossils
Ohio State University geologists have isolated complex organic molecules from 350-million-year-old fossil sea creatures -- the oldest such molecules yet found.

Treasure Trove Of Fossils Found In Limestone Cave
Remnants from a cave embedded in a limestone quarry southwest of Chicago have yielded a fossil trove that may influence the known history of north central Illinois some 310 million years ago.

Prehistoric Mystery Organism Verified As Giant Fungus
Scientists have produced new evidence to finally resolve the mysterious identity of what they regard as one of the weirdest organisms that ever lived.

Ancient DNA Traces Woolly Mammoth's Disappearance
Some ancient-DNA evidence has offered new clues to a very cold case: the disappearance of the last woolly mammoths, one of the most iconic of all Ice Age giants, according to a recent article.

An Ancient Bathtub Ring Of Mammoth Fossils
Pacific Northwest National Laboratory geologists have put out a call for teeth tusks, femurs and any and all other parts of extinct mammoths left by massive Ice Age floods in southeastern Washington.

What Did Dinosaurs Hear?
By comparing those structures and applying other rules of hearing, the scientists have devised an idea of the dinosaur’s hearing range.

Agonized Death Throes Probable Cause Of Open-mouthed, Head-back Pose Of Many Dinosaur Fossils
The peculiar pose of many fossilized dinosaurs, with wide-open mouth, head thrown back and recurved tail, likely results from the agonized death throes typical of brain damage and asphyxiation
