Cryodrakon boreas, a newly described species of giant pterosaur, was recently identified from fossils found in Canada.
The Cretaceous, the last and longest period of the dinosaur age, lasted from about 145.5 million to about 65.5 million years ago. During the Cretaceous, mammals were small, about rat size, and the land was ruled by dinosaurs, including the duck-bills (hadrosaurs), horned dinosaurs (Triceratops), long-neck sauropods (Dreadnoughtus) and the tyrannosaurs (Tyrannosaurus rex). When the 79-million-year-long period ended, largely because of a 6-mile-wide (10 kilometers) asteroid slamming into the Yucatan Peninsula, about 80 percent of all animal species went extinct, including the non-avian dinosaurs.
Paleontologists have discovered the remains of an ancient Loch Ness Monster look-alike in freezing Antarctica. And just like the legendary Nessie, it wasn't the runt of the litter.
This 92-million-year-old tyrannosaur was so small, it was only slightly larger than the skull of its mighty relative, Tyrannosaurus rex.
An ancient crab that lived during the dinosaur age was so strange, paleontologists are calling it the platypus of the crab world.
The partial skeleton of a baby Tyrannosaurus rex is for sale on eBay for nearly $3 million. Paleontologists are furious about it.
A fossil site in North Dakota preserves a unique snapshot of the minutes after an asteroid struck Earth around 66 million years ago.
What happened after the Cretaceous-ending asteroid struck Earth? A new fossil site may have answers.
A newfound dinosaur seems to wear its heart on its tail, according to paleontologists who found the enormous beast and realized this "hopeless romantic" had heart-shaped tail bones.
Different species of duck-billed dinosaurs may have "tooted" different notes out of their trumpet-like, tubular crests, new research shows.
Ancient organs rarely fossilize, so paleontologists were stunned to find the incredibly well-preserved remains of a lung that belonged to bird from the dinosaur age, a new study finds.
About 85 million years ago, when a vast sea covered Kansas, a wee, little sea monster died almost immediately after it was born.
