celophysis and eoraptor
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.
So far, Herrerasaurus is among the earliest known Dinosaur
Dinosaurs first appeared in the early Mesozoic.
In early studies dinosaurs are poikilothermic in new study shows dinosaurs are truly homeothermic
Triassic
Juassic
Early humans evolved 2.3 million years ago. That is 63.2 million years after dinosaurs died out.
Most dinosaurs were herbivores. There was a wide variety or carnivorous dinosaurs, though, and all herbivorous dinosaurs evolved from the earliest carnivorous dinosaurs. Birds are descendants of carnivorous dinosaurs.
Dinosaurs are most closely related to birds to the extent that birds are cnsidered a branch of dinosaurs.
Some dinosaurs did have spines but most did not. The main body coverings of most dinosaurs were scales and feathers.
Early man was 65 million years after the era of dinosaurs.
What most people call "flying dinosaurs" were actually pterosaurs, flying reptiles that were unrelated to dinosaurs. However, birds are considered by most scientists to be a clade of dinosaurs, and thus birds are "flying dinosaurs."
