Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been widely debated, paleontological discoveries and developmental biology studies suggest that feathers ...
A team of paleontologists from the Natural History Museum in the U.K., the University of Birmingham, also in the U.K., and Sidi Mohamed Ben Abdellah University, in Morocco, has unearthed the oldest known cerapodan ornithischian ...
Modern birds are the living relatives of dinosaurs. Take a look at the features of flightless birds like chickens and ostriches that walk upright on two hind legs, or predators like eagles and hawks with their sharp talons ...

The Triassic is one of the most important periods in the evolution of life on Earth. After one of the greatest mass extinctions 252 million years ago, not only the dinosaurs but also many other groups of terrestrial tetrapods ...
For more than 140 years, Mixodectes pungens, a species of small mammal that inhabited western North America in the early Paleocene, was a mystery. What little was known about them had been mostly gleaned from analyzing fossilized ...
More than 99% of birds can fly. But that still leaves many species that evolved to be flightless, including penguins, ostriches, and kiwi birds. In a study in the journal Evolution, researchers compared the feathers and bodies ...
How do scientists study the behavior of dinosaurs, who died 65 million years ago? After all, dinosaur fossils are rare enough as it is, and most are fragments and difficult to work with.
The end of the Cretaceous Period, 66 million years ago, marked the dramatic extinction of the dinosaurs. Until now, our understanding of this mass extinction has been largely shaped by fossils from North America. However, ...
