Leallynasaura (Pronounced: LEE-all-lin-ah-SAW-rah), was named after the paleontologist’s daughter who discovered its fossil in Dinosaur Cove, Victoria, Australia. They existed between 112-104 million years ago in the early Cretaceous period when Australia was believed to be attached to the vast polar continent where there would have been long winter with sub-zero temperatures and months without sun.
Little about it weight and height was know as only an incomplete skeleton, teeth, and a fragmentary skull of a juvenile specimen was found, but this it was gathered that leaellynasaura was an herbivore which was a size of a small turkey. It had a tough beak and a strong jaw with many self-sharpening cheek teeth. They mainly ate cycads, ferns, and conifers.
They had a skull with unusually large eye-sockets and two bumps further behind it, for its optic nerves. This had suggested that it adapted to long winter darkness of the Antarctic and implies that it could withstand low to even sub-zero temperatures. In order to do so Leaellynasaura would have to be able to generate heat leading to much speculation that dinosaurs were warm-blooded animals.
