Dinosaurs died out 65 million years ago, we know a lot about their lifestyle. Herbivores and carnivores lived in the world of dinosaurs. Some dinosaurs cared for their young. But whether they were warm-or cold-blooded has yet to be established.
Carnivores:
Most carnivores had deadly sharp teeth and claws. Some hunted in packs, some hunted alone, and othersmay have scavenged on dead animals which were possibly killed by disease.

Fast food:
Dromaeosaurus had features common to many carnivores. It was fast, agile, and armed with sharp teeth and claws.
Dromaesaurus may have hunted in packs, chasing and bringing down much larger animals.

Herbivores:
Plant-eating dinosaurs had to eat large amounts of plants every day to fuel their bodies. An herbivore's special diet needed special ways of eating and digesting food. Some herbivores teeth were shaped for chopping, raking , or crushing . Other herbivores herbivores had sharp beaks for snipping leaves and twigs . Once swallowed, these tough plants may have taken days to digest.
Grinding Gut
Barosaurus did not chew its food , it swallowed tough leaves and twigs whole . In a part of its stomach, Stones called gastroliths ground the food for disgestion.
Smooth Stones Gastroliths have
been found near the
skeletons of several
dinosaurs.
Plant Pulp:
Edmontosaurus had hundreds of though teeth packed together in its upper and lower jaws.
The two sets of teeth worked together like a pair of coarse , grinding leaves, fruits , and seeds.
Tough to eat:
We can see which plants were available to dinosaurs by studying plant fossils. Herbivores such as Parasaurolophus had strong teeth for chewing tough plants such as ferns and conifers.
Dinosaur Menu:
Many of the plants the dinosaur ate can be seen in gardens and parks today.
From the side, Baryonyx's skull appeared crocodile shaped. Baryonyx may used its long and arrow snout for catching fish.
Cutting claws:
Like Dromaeosaurus, Deinonychus had a lethal weapon - a 6-in -long (15 m) curved claw on each hind foot. When Dienonychus caught prey, it flicked the claw forward to cut deep into the victim.

Meaty Diet :
Tyrannosaurus rex was on of the fiercest carnivores. With its powerful body and massive head, it overhelmed victims, delivering fatal, biting blow with its deadly jaws.
