Herrerasaurus was one of the largest predators in its habitat. The only one larger was Saurosuchus, and it would have hunted Herrerasaurus.
Herrerasaurus is believed to be about 228 million years old.
leave alone
Herrerasaurus, with an estimated 200-300 kg in weight, was quite a bit larger than Eoraptor, which was the size of a turkey (an estimated 10 kg in weight). In fact, considering that these dinosaurs lived in the same place and at the same time (Late Triassic South America), Herrerasaurus might have actually hunted and eaten the smaller Eoraptor!
So far, Herrerasaurus is among the earliest known Dinosaur
Coelophysis, Herrerasaurus, Daemonosaurus, Eoraptor (possibly omnivorous), Lilliesternus.
One of the earliest known dinosaurs is Eoraptor. Another is Herrerasaurus. They lived 231.4 million years ago.

Most of the earliest known dinosaurs were theropods, such as Eoraptor, Herrerasaurus, and Coelophysis. There were also herbivorous prosauropods, such as Plateosaurus, and early ornithischians, such as Eocursor.
The earliest known dinosaurs were small, bipedal meat eaters (theropods). The oldest known genera are Eoraptor and Herrerasaurus, which both lived 231.4 million years ago.
Yes, the first dinosaurs evolved in the Triassic period. The earliest dinosaurs that have been discovered are Eoraptor and Herrerasaurus, which lived 231.4 million years ago.
ALL wild animals face life-threatening struggles, mainly of two types: 1) finding enough to eat; 2) avoiding things trying to eat them.
