Fifteen years ago, Mark Norell, a paleontologist at the American Museum of Natural History, discovered a clutch of dinosaur ...

Some of the soft-shelled eggs that the team analyzed belonged to Protoceratops (right), a plant-eating dinosaur that lived around 75,000 years ago in what is now Mongolia. Whether the chicken or the ...

New research suggests that the first dinosaurs laid soft-shelled eggs -- a finding that contradicts established thought. The study analyzed the eggs of two vastly different non-avian dinosaurs and ...

Eggs from the earliest dinosaurs were more like leathery turtle eggs than rigid bird eggs. Studies of fossilized embryos from two kinds of dinosaurs, one from early in dinosaur history and the other ...

Paleontologists have long thought that all dinosaurs laid hard-shelled eggs, much like crocodiles and birds (their descendants) do. But a new analysis of fossil eggs discovered in the Gobi Desert ...

The first dinosaurs laid soft eggs and it was only later that some groups evolved eggs with hard shells, according to new research. The finding overturns a long-standing assumption that dinosaurs ...

Researchers have found evidence of a previously unrecognized soft tissue structure in the cheek region of many dinosaur species, which they've called the "exoparia." The finding deepens our ...

A new study sheds light on how these reptiles become “mummies” and paints a picture of what these ancient animals looked like ...

At first glance, dinosaur fossils and modern cancer research may seem worlds apart. But a new study suggests that soft tissue preserved for millions of years inside ancient bones could offer valuable ...

Paleontologists spotted injuries on the tails of duck-billed dinosaur fossils that might have occurred during mating.

Paleontologists have long wrestled with the challenge of identifying the genders of dinosaurs from the fossils they leave ...

New research suggests that the first dinosaurs laid soft-shelled eggs--a finding that contradicts established thought. The study, led by the American Museum of Natural History and Yale University and ...
