Primordial World: dawn of an empire

Carnivores. Dinosaurs like Eoraptor, Herrerasaurus, and Coelophysis were among the first dinosaurs ever.

(Eoraptor, 1 meter)

(Herrerasaurus, 3-5 meters)

(Coelophysis, 2-3 meters)

He is right all dinosaur started off form a small meat eating creature 

Small carnivorous dinosaurs such as Eoraptor lunensis and Herrerasaurus ischigualastensis and later the various known species of Coelophysis were among the first dinosaurs to roam the Earth. Shortly after those, herbivorous prosauropods such as Plateosaurus engelhardti and Panphagia protos started to pop up.

Yes the carnivores came first, but some would argue that the herbivores did more to cement the dinosaurs as the dominant species. 

Yeah, the first dinosaurs that we know of are Eoraptor, Herrasaurus and Ceolophysis 

Compsagnathus was early as well, also Postasuchus, which wasnt a dinosaur, but this counts for any carnivore at the time right?

no, only dinos.

Well crap, well all i can think of off the top of my head that are Carnivores have already been listed.

Well, there's alsso Tawa hallae, and Gojirasaurus quayi...

I haven heard of Tawa Hallae till a few years ago, it was found in 2006 and found somewhere with the word Grizzly in it.

Grizzly Creek or Grizzly Valley, its just somewhere down in Mexico.

Well, everyone else has said pretty much everything that needs to be said. I think the Triassic was dominated by Carnivores because the predators were still small enough to survive off rodents, and there were still various other non dinosaur creatures that were still around. 

The carnivores definately did, with creatures like:

Eoraptor

Coelophysis

Herrerasaurus

Gojirasaurus

and Tawa

All dinosaurs evolved from the thecodonts, a group of rather primative reptiles that dominated the landscape up until the mid triassic. From there, a sub group began to take shape, diverging from the thecodonts into swift lightly built carnivores and the odd omnivore.

This is a global series, right? as in the dinosaurs that were alive at that time all over the earth?

Well, i've got a few that haven't been mentioned yet..

Massospondylus carinatus

Lesothosaurus diagnosticus

 Liliensternus liliensterni

Halticosaurus longotarsus
