Recent history equivalent are Native Americans from the great plains, they were the tallest humans when europeans arrived with some tribes being 6'0 , taller than Scandinavians, while central americans barely reached 5'5. Hunting large mammals like elk and buffalo and rich vit d diet seem to be some of the reasons of height discrepancy.

  2. The funny thing is that Coelophysis wasn't unique at all, other several arcosaur groups developed a very similar body shape such as selesaurus lewisuchus,it still a mystery how exactly dinosaurs surpassed other reptiles at the end of triassic period, but the increase of humidity seemed to help the increase of dinosaur population.
