Where does the Herrerasaurid live?

Herrerasaurids were a group of primitive dinosaurs or close relatives of dinosaurs that lived in the Late Triassic period, about 233 to 199 million years ago.
They were among the oldest known dinosaurs, and their fossils have been found mainly in Argentina and Brazil, but also in North America, Poland, and Zimbabwe.

Herrerasaurids were carnivorous animals that had long, powerful hind legs for running and short forearms with three fingers and claws for grasping prey.
They had a hinged lower jaw that could slide back and forth, which may have helped them to hold and slice their food.
They also had a large terminal expansion of the pubis bone, which may have supported a large belly or helped to balance their long tail.

Herrerasaurids were relatively small-sized dinosaurs, normally no more than 4 meters (13 feet) long, although some specimens may have reached up to 6 meters (20 feet) long.
The best known representatives of this group are Herrerasaurus ischigualastensis and Staurikosaurus pricei, both from the Ischigualasto Formation and the Santa Maria Formation of Argentina and Brazil, respectively.
Other possible members of this group include Sanjuansaurus gordilloi, Gnathovorax cabreirai, Chindesaurus bryansmalli, Caseosaurus crosbyensis, and an unnamed species from Poland and Zimbabwe.

The exact position of herrerasaurids in the dinosaur evolutionary tree is not clear, as they have a mixture of very primitive and derived features.
Some studies have suggested that they are basal theropods, the group that includes all carnivorous dinosaurs and birds, while others have suggested that they are basal saurischians, the group that includes both theropods and sauropodomorphs, the long-necked herbivorous dinosaurs.
Herrerasaurids may have been among the first dinosaurs to diversify and spread across the continents in the Triassic period, before becoming extinct by the end of the stage.

What does the Herrerasaurid look like?

You are the oldest of your kind
A hunter of the Triassic time
Your teeth are sharp, your claws are curved
Your body is sleek and well-preserved

You run with grace on two long legs
You chase your prey with no regrets
You are the master of your land
You rule with strength and skill and cunning

But in your heart there is a flame
A longing for a mate to claim
Someone who shares your ancient blood
Someone who makes you feel alive

You search the valleys and the hills
You listen for a distant call
You hope to find your perfect match
A Herrerasaurid who loves you back
