ENVIRONMENT & CLIMATEScientists reconstructed the cloacal region of Psittacosaurus, a dinosaur as big as a Labrador dog that lived, to know how dinosaurs mate finally.
Researchers were unable to trace the origins of pterosaurs for 200 years, but a new study sheds light on the mystery of the first-known flying vertebrates.
A study reports the discovery of a complex tissue arrangement in early mammals that led to having serrated teeth - a feature previously thought unique to carnivorous dinosaurs.
Scientists have recently discovered a flamboyant, chicken-sized dinosaur that could shed new light on how birds and fowls like peacocks have their practice of "showing off."
A new study suggests that prehistoric algae, marine plant life that lived alongside the dinosaurs, managed to survive the extinction event that killed the large reptiles - by learning how to eat other living beings.
Some 240 million years ago, during the time of aquatic reptilian predators, one species used its short, flat tail to balance and float motionless as it hunted for prey.
Yi and Ambopteryx were a dead end on the evolutionary road to bird flight, experts say. The finding of two tiny dinosaurs with bat-like wings was a paleontologist's fantasy a few years ago.
British auction house Christie's will be auctioning off one of the most complete Tyrannosaurus rex skeletons ever discovered, expecting to fetch a record-setting price on October 6.
Hibernation is a common defense mechanism where an animal moves to a state of minimal activity to survive tough winter months - and new fossil suggests that it occurred back in the Early Triassic period.
Tuataras are some of the oldest living species that have existed since the time of the dinosaurs. Researchers from New Zealand and Australia were surprised to discover just how complex the tuatara genome is and its rightful place in the tree of life.
Osteosarcoma, common, malignant bone cancer in humans, was recently linked to a herd of Centrosauruses from about 75 million years ago. Dinosaurs surviving cancer also revealed an advantage of belonging to a herd.
Martin Sander originally discovered a pregnant Ichthyosaur, naming her Martina. She is now in the LA Museum of National History with the help of Tom Young, a craft brewer.
According to research, an area in the Sahara, now known as south-eastern Morocco, was debatably the most dangerous place in the history of planet Earth. Scientists say it is a place where no human time-traveler would survive because of the creatures that lived there. What kind of creatures lurked the area? Click the link above to find out.
