What did the dinosaurs do on earth?

Answer 1

Dinosaurs spent their time eating, migrating, mating, or defending their territories. What they did was related to the time of year. For example, they mated in the spring and migrated in the late fall.

Answer 2

Dinosaur behavior is difficult for paleontologists to study because dinosaurs have been dead for a long time, no human has ever witnessed them in action, and we can only find clues as to how they might have behaved through their fossil remains, which are often sparse. Despite this, we have gotten much insight from these fossils. We look at their teeth and stomach cavities to see what they ate. We also examine their skulls to find out how smart they were. We can make inferences based on how animals of today live. Some dinosaurs traveled in herds, like today's bison. Others hunted in packs, like today's wolves.

Herbivore BehaviorHerbivore behavior varied. They may have traveled in herds or small groups. Some herbivores such as Stegosaurus and Ankylosaurus probably lived alone, considering they were well-equipped to do so.

Ceratopsian Behavior

The Ceratopsians were the "horned faces". They were four-legged herbivores with short necks, frilled heads, and beaked mouths. They may or may not have had one or more horns. Examples include Triceratops and Styracosaurus.

Based on fossil remains these dinosaurs usually traveled in herds of various sizes. They ate small plants that grew on the ground and probably maintained social structures and cared for their young.

Based on their frills and horns these dinosaurs could have been very agressive. They not only used their weapons to defend against predators but also when fighting against each other, usually for mating rights.

Ornithopod Behavior

The Ornithopods had "bird feet" and are recognizable by their "duck-billed" mouths, small front legs and large hind legs. They were grazers like the ceratopsians, and they were also fast. Examples include Iguanodon and Parasaurolophus.

Hundreds of fossil footprints that have been found suggest that they moved in great herds, like today's bison.

Based on their skull structure they also had a unique way of communication, and some could make deep honking sounds to communicate with other herd members.

Like the ceratopsians, parental care probably continued long after birth.

Sauropod behavior

The sauropods were the largest animals to ever walk the Earth. They had long necks and long tails. Due to their sheer size and weight, all they ever did was eat (and of course, mate). They most likely traveled in large, unstructured herds.

Carnivore BehaviorAll carnivorous dinosaurs were theropods.

Theropod Behavior

All the carnivorous dinosaurs were theropods, so they're behavior varied greatly. They were by far the smartest dinosaurs.

The smaller theropods such as the raptors probably hunted in packs, much like today's wolves. This is based on groups of fossils found together and also footprints. The raptors were small, light, fast, and among the smartest dinosaurs. They cooperated well, meaning they could take down even the largest herbivores. They were equipped with razor sharp claws to cut through flesh.

Some raptors, such as Velociraptor, chose not to hunt larger dinosaurs, and instead hunted for small lizards and insects, contrary to popular belief. The "egg thieves" such as Oviraptor probably stole and ate eggs, although new discoveries suggest they probably ate other small animals too.

The largest theropods included Tyrannosaurus and Allosaurus. They were among the most ferocious predators, hunting and eating almost any other dinosaur, except for the largest sauropods. They had large teeth that could tear flesh and crush bone. They were far from dumb, could smell food that was miles away, and used several strategies to hunt their prey.

Still other theropods were scavengers or were not good at hunting. Despite his size, Spinosaurus probably scavenged or hunted fish rather than attacking other dinosaurs. Even the large predatory theropods like Tyrannosaurus were often forced to scavenge when it was necessary.

_______________________

It is important to understand that while we have learned a great deal about dinosaurs through their fossil remains, we will never be quite sure exactly how these monsters behaved. Much of their behavior is inferred, with the assumption that they acted much like today's mammals, the current dominating class. While some behavioral inferences will never be clearly known, such as their mating rituals or social behavior, others are fairly accurate, such as Tyrannosaurus being a super-predator or herbivores traveling in herds. As we continue to uncover more fossil evidence we will gain further and more accurate insight into the behavior of these fascinating creatures that lived deep in the past.
