Walking with Dinosaurs--the conclusions

["Brian M McCarthy" <brian.mccarthy@snet.net>]

From the WWD glossary:

Pack hunters:

Allosaurus  This fierce two legged carnivore lived in the Late Jurassic period. It inhabited the plains, and normally hunted alone. It would hunt in groups to tackle the largest prey. Coelophysus This small two legged carnivore lived in the Late Triassic period. It inhabited river valleys and scrubland around the plains, hunting alone or in small groups. At the end of the dry season Coelophysis formed large packs to hunt. And herds: Placerias  This large, four legged herbivore lived in the Late Triassic period. It lived on the plains where it grazed in large herds, eating low-lying plants like ferns.  Stegosaurus:  This huge, four-legged herbivore lived in the Late Jurassic period. It is thought to have inhabited the plains and grazed in large herds alongside other herbivores like Diplodocus.   Eustreptospondylus may have been a scavenger that could swim from island to island when attracted by the smell of meat, using its tail as a balance [in water?].

Pterosaur
Literally "flying reptile". These creatures were distinct from dinosaurs, none of which ever flew.
Reptile
A group of air breathing, scaly-bodied animals with back bones that evolved from the amphibians. They fertilise their eggs internally and are not reliant on water to lay their eggs in. Modern turtles, crocodiles, lizards and snakes are all reptiles.

Tyrannosaurus
This huge two legged carnivore lived in the Late Cretaceous period. It roamed around the forests and marshes searching for prey. Its long, serrated teeth and enormous jaw made it a fearsome predator.

 

Settles a great deal.
