Omnivorous dinosaurs were widespread throughout the world and existed during all three Mesozoic eras. They were unique in many respects, not only because they ate both plants and animals’ meat, but also because they were capable of adapting to their surroundings and living in many ecosystems.

Even though scientists have done a lot of extensive searches to find them all still to this date they have found various types of them but the most prominent were: Oviraptorosaurs, Ornithomimosaurs, and Troodontids.

Omnivores are special in terms of the fact they are adaptable to almost any kind of habitat. Because they were not known to have a special kind of diet they had a pretty easy time surviving almost anywhere.

Even if they had nothing to eat they ate dinosaurs species that were somehow smaller than them and if that didn’t work out they would even munch on rocks. Whether the time of the year was hot or cold they lived in every habitat and ate everything as a portion of food.

Moreover, these omnivores had these long lengthy teeth like the allosaurus that were as sharp as a butcher’s knife that helped them to munch on almost every kind of food. Besides these visual features, omnivores had this intestine which would easily digest whatever they ate.

We are already aware of that how different species of omnivore dinosaurs can exist and not going to lie here, but the Jurassic Park videos have at least provided us with a rough thought of what kind of dinosaurs and their species lived back millions of years ago. We will be going to discuss the details and brief descriptions for each of them one by one.

The oviraptorosaurs were as heavy as 2 tons, and lengthwise was 8 meters long. They had this beak and skull that was somehow similar to modern-day birds. Such omnivores were able to digest vegetation as well as other animals and plants.

Because of their feathery representation, they were considered primitive birds of that time. Some of these omnivores, like the Oviratorosaurs in Mongolia, even ate insects. These Mongolia species had these short necks and were 1 meter in length.

Troodontids were yet another group of omnivorous dinosaurs. They were among the smallest dinosaurs, but they were also intelligent, and their brains were larger than their bodies in comparison. They ate depending on wherever they lived. Moreover, they were short in length as compared to other omnivore dinosaurs found at that time.

The potential number of dinosaur species that could have existed over the length of three Mesozoic era eras has been calculated by scientists to be 1,543-2,468. According to paleontologists, about 65% of the animals were herbivores and 35% were carnivores.

The proportion of omnivorous dinosaurs was quite small—between 1% and 2%. Considering that there are more than 2000 dinosaur species, 1-2% of those are 20 to 40 omnivorous dinosaurs that have been discovered or are still undiscovered is indeed a small fraction to understand how they lived in that time.

Depending on what is available, a dinosaur’s diet can frequently be ascertained by looking at its teeth or taking samples from its intestines. There were some dinosaurs with middle-of-the-road-sized teeth. It may be presumed that they ate both plants and animals or were omnivorous if there are no stomach samples available to definitively determine their diet.
