趣味知識

Sinovenator is one of the oldest and most primitive troodontids, a group of dinosaurs very closely related to birds.2 1

Its pubic bone pointed backward, like in dromaeosaurs and early birds, showing that later troodontids evolved a forward-pointing pubis separately.1

Sinovenator had a large brain for its size, making it one of the smartest dinosaurs of its time.1

Hundreds of Sinovenator fossils have been found, but most are still waiting to be studied.1

The species name 'changii' honors Chinese paleontologist Meemann Chang for her work on the Jehol Biota.1

Sinovenator lived alongside many other feathered dinosaurs and early birds in the Jehol ecosystem.1
