Datu dibertigarriak
Caenagnathasia is the smallest known oviraptorosaur and one of the smallest non-avian dinosaurs. Its skull was only about 7.6 centimetres (3 inches) long.1
It lived about 90 million years ago, making it the oldest known caenagnathoid.1
The first fossils were just two fused lower jaw bones, found in Uzbekistan.1
Scientists think it was feathered, like other oviraptorosaurs, and looked bird-like with a beak and long neck.1
In 2015, new bones were found, including vertebrae, a dentary, and a femur, which helped confirm it belonged to the Caenagnathidae family.1
The name honors Gerbert Genrikhovich Martinson, a scientist, in the species name martinsoni.1

Mito-hauslea
