Researchers describe a hitherto unknown bird from the late Jurassic period. It is the second bird capable of flight, after the famous Archaeopteryx, to be identified from this era. […]

'Suskityrannus gives us a glimpse into the evolution of tyrannosaurs just before they take over the planet,' said Sterling Nesbit. […]

Before they evolved the ability to fly, two-legged dinosaurs may have begun to flap their wings as a passive effect of running along the ground. […]

The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 ton giants so successful? A new study shows that their special adaptations in teeth and jaws and in their head crests were crucial, and provides new insights into how these innovations evolved. […]

A new study has identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems. […]

Scientists are among the millions of die-hard Game of Thrones fans digesting the show's finale today. […]

A 24-tonne dinosaur may have walked in a 'high-heeled' fashion, according to University of Queensland research. […]

Bedbugs—some of the most unwanted human bed-mates—have been parasitic companions with other species aside from humans for more than 100 million years, walking the earth at the same time as dinosaurs. […]

An international team of paleontologists has united to study important fossil footprints recently discovered in a remote location within Grand Canyon National Park, Arizona. A large sandstone boulder contains several exceptionally well-preserved trackways of primitive tetrapods (four-footed animals) which inhabited an ancient desert environment. The 280-million-year-old fossil tracks date to almost the beginning of the Permian Period, prior to the appearance of the earliest dinosaurs. […]

Researchers in Germany have unearthed a new species of flying dinosaur that flapped its wings like a raven and could hold vital clues as to how modern-day birds evolved from their reptilian ancestors. […]
