An international team of researchers has resolved the evolutionary relationships of Necrolestes patagonensis, the so-called “grave robber” because of its burrowing and underground lifestyle.…

Small critters tend to evolve into bigger beasts, according to paleontologist Edward Cope, what is now known as Cope's Rule. Using statistical modeling methods, a new test of this rule as it applies…

A spectacular find of some 1,800 fossilized mesa chelonia turtles from the Jurassic era has been uncovered in China’s northwest province of Xinjiang. Today one of the world’s driest regions, 160…

The coelacanth has one of the longest lineages, 400 million years, of any animal and is the closest living fish to all vertebrates alive on land. Now it has a new member. Pieces of tiny fossil skull…

Twenty years ago Mary Schweitzer found herself the closest that anyone has ever been to a living dinosaur. As she examined a thin slice of a T. Rex bone fragment under a microscope, she realized she…

Researchers have found what they say is the only fossil ever discovered of a spider attacking prey caught in its web – and it dates back 100 million years.  The extraordinarily rare fossils are…

Duck-billed dinosaurs, also known as hadrosaurids, had an amazing capacity to chew tough and abrasive plants with grinding teeth more complex than those of cows, horses, and other modern grazers.…

A set of fossil footprints in Joggins, Nova Scotia have been identified as the world’s smallest - among vertebrates to-date, anyway. The footprints were found at Joggins Fossil Cliffs. A fossil…

Analysis of the abdominal contents of two dinosaur fossil specimens reveals new information about their hunting and eating behavior, according to a new report.  They may have been stealth…

Dragonflies, from the order Odonata, have been around for over 250 million years. The most conspicuous difference in their evolution over time is the steady shrinking of their wingspan from well over…
