Herrerasaurus is a genus of basal theropod from the Carnian age of the Late Triassic period, around 231 million years ago. It contains one species, H.ischigulastensis.
In Real Life
Herrerasaurus was found in the Ischigulasto Formation of Argentina, and was around 6 meters long. Its legs were strong, with a short thigh and a rather long foot, indicating it was probably a fairly swift runner.
The environment Herrerasaurus lived in was a volcanically active floodplain, which was covered by forests and had strong seasonal rainfall. The climate was moist and warm, although subject to seasonal variation.
Herrerasaurus likely preyed on small-to-medium-sized animals, such as the small ornithischian Pisanosaurus, as well as the more plentiful rhynchosaurs and synapsids. It was likely preyed upon by Saurosuchus; puncture wounds matching the large crocodylomorph were found in a Herrerasaurus skull. A pit in a skull bone of a specimen was attributed to intraspecific fighting.
Although its feet had five toes, only the middle three touched the ground, and only digits I, II, III, and IV had claws. The arms were less than half the length of the legs, with hands bearing five digits; only the first two fingers and the thumb bore claws, the remaining two digits were small and lacked claws altogether. It's skull also had a flexible joint in the lower jaw; a feature unusual among dinosaurs, but that has also been seen in some lizard species.
Due to its basal status, Herrerasaurus skull was more similar to more basal archosaurs like Euparkeria then to more derived theropods; it had five pairs of fenestrae in its skull, two of which were for the eyes and nostrils. Between them were two pairs of antorbital fenestrae and a pair of tiny, slit-like holes called promaxillary fenestrae.
Also due to this basal status, Herrerasaurus placement in the dinosaur tree has been rather variable, due to it's a combination of basal and derived traits. Initially described as an early carnosaur, it was then hypothesized to be a prosauropod, a basal saurischian, a basal dinosaur, and even outside of Dinosauria. Currently, there are two hypotheses on the placement of Herrerasaurus; some believe it to be a basal member of Saurischia, others believe it to be a basal member of Theropoda.
In The Isle
Herrerasaurus is a small animal that can be easily killed by larger creatures, its favored prey are Dryosaurus and Psittacosaurus. Herrerasaurus size makes ambushing prey an easy task, due to its fast speed it can easily take down small herbivores. It can also scavenge from other carnivores although very risky as bigger dinosaurs can easily kill an Herrerasaurus.
The Herrerasaurus is the fastest dino in the game, its running speed is almost identical to the Utahraptor's ambush speed. However as it is not implemented into Survival mode it is not known to rival any other survival dinosaurs speed.
It is currently only playable in Sandbox mode.
"The Herrerasaurus is one of the islands more colorful inhabitants. At first glance, it may not seem as threatening as some of the other carnivores but is no less equipped to devastate the unsuspecting. If you find yourself in dense jungle, don't forget to look up."

Behind the Scenes
The model used for the Herrerasaurus is one of Vlad's (Swordlord3D) older models.
It has been stated by the devs that the Herrerasaurus will get a rework in the distant future.
Like the Therizinosaurus, the Herrerasaurus is getting a remodel. This seems to be part of the effort to make all the fauna in the game completely original. The Quetzalcoatlus may also be getting a remodel.
