趣味知識

Geminiraptor is named after twin geologists Marina and Celina Suarez, who discovered the fossil site. The name means 'twin seizer'.1

Only one piece of the skull, an upper jaw bone called a maxilla, has been found. Scientists think the whole dinosaur was about 1.5 meters (5 feet) long.1

Its upper jaw had at least 19 teeth, and the sockets were square-shaped, which is unusual. This feature is only known in one other troodontid, Sinovenator.1

Geminiraptor's upper jaw had a big air pocket inside, giving it a triangular shape when cut across. This helped make the skull lighter.1

It lived alongside other dinosaurs such as the theropods Falcarius and Yurgovuchia, the sauropod Mierasaurus, and the large plant-eater Iguanacolossus.1

Geminiraptor was a troodontid, a group of smart, bird-like dinosaurs. It was one of the first troodontids found in North America from the Early Cretaceous.1 2

發現: Geminiraptor was named by Phil Senter, James I. Kirkland, John Bird, and Jeff A. Bartlett in 2010. It was described from a single upper jaw bone found in Utah, USA.1
仍有爭議: Scientists are not sure exactly where Geminiraptor fits in the troodontid family tree. It might be closely related to Sinovenator because both have bony walls between their tooth sockets.1
