吃：肉最早的恐龍三疊紀晚期

Gnathovorax was an early meat-eating dinosaur that lived about 233 million years ago in what is now Brazil. It was a fast and smart hunter with sharp teeth and claws, and its brain had special parts that helped it control its eyes and head while chasing prey.1 2

酷東西

趣味知識

Gnathovorax is the most complete and best preserved herrerasaurid dinosaur ever found, with an almost complete skeleton that is barely squashed.1

Scientists used CT scans to make a digital model of Gnathovorax's brain, which showed it had a large floccular fossa lobe, a brain part linked to eye and head control in active hunters.1 2

Gnathovorax lived during the Carnian stage of the Late Triassic, about 233 million years ago, making it one of the earliest known dinosaurs.1 5

It was a herrerasaurid, a group of early predatory dinosaurs that lived only in the Triassic period, before theropods took over as top hunters.1 2

The fossil of Gnathovorax was found lying next to the remains of a rhynchosaur and a cynodont, which were other animals that lived at the same time.1

Gnathovorax was named after the paleontologist Sérgio Furtado Cabreira, who discovered the specimen, and its name means 'jaw devourer'.1
