Dinosaurs

The smallest brain to body ratios of dinosaurs were those of sauropods. Despite being the largest animals ever to walk on land, their brains were only the size of a tennis ball. However, that was sufficient, and sauropods were widespread until the extinction of all dinosaurs, so their tiny brains don't seem to have been much of a deficit.

There is no such place. That is because dinosaurs died out long before humans evolved, so they could not have left footprints near human footprints, and vice versa.

There is no evidence in the fossil record that suggest that Archosaur Postosuchus ever ate eggs.

The preserved stomach contents of a specimen found in modern day North Carolina suggest it was purely a carnivore preferring live animals or perhaps carrion. They found parts from 2 synapsids (mammal like reptile) named Dicynodont and Plinthogomphodon and a giant primitive amphibian named Temnospondyli.

The fossil was also found on top of another archosaur called Dromicosuchus. They found Postosuchus teeth marks on the head and neck of the Dromicosuchus

Nobody really knows because there are no fossils with skin that has colors on them.

Excluding birds (a subgroup of dinosaurs), they lived for 166 million years, which is a long time for an animal group. Including birds, they have been around for 231.4 million years so far, and will probably continue to exist as long as there is vertebrate life on land.

Dinosaurs were decomposed by the same types of organisms that decompose carcasses today, if they weren't scavenged to the bone by a different hungry dinosaur. Such organisms include insects, worms, and bacteria.

Massive! Huge! Deinosuchus was a crocodile in the Cretaceous period was 36 feet long (12 meters) and wieghed 3000 kilograms. It ate fish and even dinosaurs like parasolophus, jumping out of the water to catch them.

The Reptiles - it was the age of DINOSAURS.

Birds evolved from a group of Saurischian dinosaurs known as theropods. The theropods include dinosaurs such as Tyrannosaurus, Velociraptor, and Deinonychus. Theropods were predators who walked on two feet and had relatively small arms. Some of these dinosaurs were small and started growing feathers, at first to keep warm. Eventually these feathers became adapted for flying.

Rex definetly,because of fast attacks.

Dinosaurs first evolved during the Triassic, when all the continents were joined together. Hence, the spread to all continents. When the continents split apart, dinosaurs still lived on all of them.

paileeology. that's when you study fossils.

The Tyrannosaurus.

The Water When The Dinosaurs Lived Is The Same As The Water We Drink today.But We Make Changes To The Water,Even If We Do It Will Be The Same Water As The Dinosaurs Drank(Get It?)

Coelophysis was named by the infamous Edward Drinker Cope.

when the dinosaurs roamed the earth's environment was superber was full of greenery. Ofcourse at that times there were several frequent ice ages coming in time having lot of damage to the living beings at that moments of that stage.

Baronyx was well up the food chain, but it wasn't an apex predator, so some of the larger carnosaurs could have looked on it as a potential meal.
