Byronosaurus jaffei

† Byronosaurus jaffei is the type species of the troodontid genus Byronosaurus from the Late Cretaceous Djadokhta Formation of Mongolia. Named in honor of collector Byron Jaffe, this small carnivorous theropod weighed approximately 3–4 kg and measured roughly 1.5 m in length. Its unserrated teeth differ from many troodontids, hinting at a specialized diet. Specimens have been found in close association with Oviraptor nests, raising questions about interspecies ecology.

Diet & Feeding

Time Period

Cretaceous Late Mesozoic Era

Byronosaurus jaffei lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
