The dinosaur human being was filled v herbivore plant-eating dinosaurs and was approximated to be around 65%. Over there were likewise carnivore meat-eating dinosaurs, which make up about 35%. Additionally, there to be omnivorous dinosaurs, which to be a tiny percentage, around 1-2% of all dinosaurs. This dinosaurs can be called “opportunistic” eat dinosaurs. Imagine you room an omnivore dinosaur in a habitat wherein all the vegetation dries up, and also there are no environment-friendly plants come eat. Suddenly, a small flat lizard runs right in front of you…a tasty meal!

So, what walk omnivorous dinosaurs eat? Omnivores were opportunistic dinosaurs the were able to eat both plants and also meat. They ate seeds, plants, insects, little mammals, reptiles, and also even other tiny dinosaurs! your digestive tracks to be able come digest both plants and animals. A surprising reality is that there is fossil evidence some omnivores also ate crustaceans. 

It’s exciting to keep in mind that the dinosaur civilization was distinctive with many habitats and species. Castle were different from one an additional in their means of survival, habitats, characteristics, and nutrition. As paleontologists placed the puzzle pieces with each other from fossils, correlation to contemporary birds and reptiles and also improved scientific techniques around what they ate and also how they pursued becomes clearer every year. 


Omnivorous dinosaurs live in many places approximately the world and also during all three periods of the Mesozoic era. What they to be like, what they eat, the benefits they had actually over herbivores and also carnivores, and some funny facts is what we will cover in this article. Let’s acquire started! 

I’ve researched information to compose this post from countless sources – multiple net sites and also magazines. However, some of the finest reference understanding is indigenous books.

Were there Omnivore Dinosaurs? those Special about Them and How carry out They to compare To modern-day Omnivores?

In plenty of ways, omnivorous dinosaurs were unique not just in their capability to eat both plants and meat but also their capacity to adapt and also survive in different habitats. Stop look closer at some of the details and compare castle to modern-day omnivores.

Habitat was crucial for the diet of an omnivore dinosaur. Relying on the habitat, an omnivore dinosaur might eat plants or emphasis on hunting, being able come digest both food resources –

Dinosaur Diet Differences

The Carnivorous Dinosaur Diet

Carnivorous dinosaurs were predatory meat-eaters and needed to catch and also kill your prey. Because of this, they needed sharp teeth, resembling knives, that might stab through their meal and kill them. 

However, their diet additionally depends on how big and fast they are. Some carnivorous dinosaurs ate just smaller animals and dinosaurs, while others choose T. Rex and also Allosaurus were apex predators that were terrific hunters and hunted bigger prey. 

Carnivore dinosaurs had these features:

● Sharp teeth to tear flesh● A digestive device that can streamline eating due to the fact that the proteins were simpler to digest● Were fast, agile, and excellent hunters

The Herbivorous Dinosaur Diet

Herbivorous dinosaurs had actually a strictly plant-based diet, which was inferred from their wide, blunt teeth that can macerate tree material. Countless of the plant-eaters to be long-necked, which helped them reach greater into high trees for more food. 

Others were smaller sized such as the Stegosaurus or Triceratops that normally fed ~ above plants, seeds, shrubs, and little trees. Duck billed herbivore dinosaurs were grazing dinosaurs. 

Herbivore dinosaurs had actually these characteristics:

● Flat, blunt this for chewing vegetation● A frequently more facility digestive mechanism able come digest bark, jaw needles, and also plant shoots● Generally slower and also lived in herds. Some herbivores to be grazing dinosaurs

The Omnivorous Dinosaur Diet

Omnivorous dinosaurs ate both plants and also animals, which offered them a variety of food choices. Relying on how large they are and also how capable they are of searching prey because that food, your diet deserve to include small insects, plants favor shrubs and tiny trees, dinosaur eggs, small mammals and lizards, and in part cases, even tiny dinosaurs.

Omnivore dinosaurs had these characteristics:

● Omnivores had actually sharp this for eat meat and hind this that were blunt for chewing vegetation● Their digestive mechanism was qualified of eating both meat and also plants, based upon a couple of of the fossils found● The bulk of Omnivores were believed to it is in smaller-sized, agile-moving dinosaurs, with the exception of Deinocheirus, which was big in comparison (Source)

Why Is It better to it is in an Omnivore? part Modern-Day pet Comparisons

If we think around the different dinosaur habitats the existed in the Mesozoic era, we can see that the habitats can be harsh to live in. Detect food in a far desert climate with little water can be daunting if you are a herbivore dinosaur. 

Seasonal flooding in floodplains locations could wipe out all the hunting grounds, and also that would certainly be life-threatening if you to be a carnivore dinosaur. As an omnivore, you can adapt come the various habitats and eat both plants and meat. 

Consider the modern-day coyote and also raven, two successful contemporary desert animals. They space able to survive in desert climates, eating little rodents or vegetation if necessary when the rodents no plentiful. Similarly, desert areas during the Jurassic era might be an overwhelming for dinosaurs uneven they to be omnivores. (Source)

Did gift an Omnivore Dinosaur offer Them an advantage Over Carnivore and Herbivore Dinosaurs?

It’s no 100% clear if over there is an evolutionary benefit to being an omnivore, as well as being able to make it through in different habitats and eating both meat and also plants. The in chin is an advantage, however let’s watch deeper.

Scientists show that meat is a source of protein that is conveniently digestible and also can aid animals grow much faster if they have actually the right digestive system. Omnivores had this form of cradle system. Also, plant eaters had a complicated digestive system, i m sorry omnivores had actually a streamlined version of. It perhaps resulted in them gift able to be much more agile. 

Whether these services led to advantages over various other dinosaurs is a mystery, but let’s say it wouldn’t hurt its possibilities of survival. 

Some facts – What varieties of Omnivore Dinosaurs space There and How Many?

Although a bit less common and also less recognized than strictly herbivorous and carnivorous dinosaurs, omnivorous dinosaurs definitely existed. Paleontologists have actually identified and classified the major groups that dinosaurs that were omnivores.

Gallimimus was an Orinthomimosaur, among the groups of dinosaurs the was established to be omnivorous –

The Different types of Omnivore Dinosaurs 

Three main teams of dinosaurs were omnivores. These are Oviraptorosaurs, Ornithomimosaurs, and also Troodontids

The first main team of omnivores, the Oviraptorosaurs, to be as lot as 8 meters long and weighed up to 2 tons. 

They had a beak and also skull, i beg your pardon was familiar to contemporary parrots. Lock are thought about to have actually been feathered dinosaurs, and ancestor of birds. In part ways, they to be primitive birds. 


● Were able come digest vegetation with the aid of gastroliths, which space rocks in the stomach. It’s comparable to contemporary birds

● Had solid beaks come break open up shells of mollusks and also crustaceans. It also aided in breaking shells of dinosaur eggs

● Fossil proof of the stomach contents of a Citipati found a fossilized Troodontid skull, which indicates they could hunt and eat various other smaller dinosaurs

The 2nd group to be Ornithomimosaurs, a surname which means they “mimic birds.” In part ways, lock looked like birds, native the mine to their digestive system and the idea that some scientists believe this species had feathers. 

In some ways, these dinosaurs to be the closest to gift primitive birds. 

● They only had actually three toes on each foot and only three phalanges, or fingers, on every hand. 

● The beak short teeth, and they had weak jaw muscles. 

● For digesting plants, your stomachs also had plenty of gastroliths in your stomachs.

Troodontids were another group the dinosaurs the were omnivores. Lock were one of the the smallest dinosaurs, however they were the most intelligent dinosaurs, and they had a bigger brain relative to their body mass. 

 Troodontids were an ext opportunistic omnivores, meaning that they ate whatever was approximately them once they were hungry. 

● They had actually loved come eat seeds, fruits, and also nuts. 

Lizards were existing in all durations of the Mesozoic Era and also would have been a perfect meal because that an omnivore dinosaur –

● If the chance came, they would certainly eat dinosaur eggs, smaller dinosaurs, insects, and also lizards.

Some of the Omnivore species described and listed below or in the table are more well-documented than others, early to differences in the variety of discovered fossils or fossil preservation levels when they to be found and studied by paleontologists. (Source)

Most of this dinosaurs provided live throughout the late-Cretaceous period, 66 million year ago, and also existed till the mass extinction event. Paleontologists can describe the conclusions around diet by researching the teeth structures and the fossilized materials in the dinosaur’s stomach and also intestines.

What was the biggest Omnivore Dinosaur?

Deinocheirus to be the greatest omnivorous dinosaur, i m sorry is also considered to it is in a an enig – why it to be so big? many of the other identified omnivores were small, and also this one sticks out as a giant. (Source)

The Deinocheirus to be a large ostrich-looking dinosaur and ate plants and also fish. It was famous due to its 8-foot-long hands. Fossils were found the very first time, in Mongolia, in 1965, and paleontologists were amazed come have discovered a pair of hands that were bigger 보다 an average man’s height. On each hand, there were only three finger with lengthy nails. The biggest fossils measure 12-meters in length, denote a large body size. 

It had actually a 1-meter lengthy skull and virtually 3-meter-wide ostrich shame hip. The beak attached to the skull was similar to modern ducks, which suggested to scientists that they lived near shallow waters because that fishing and also grazing small plants. 

How many Omnivorous Dinosaurs to be There? Table of Omnivore Dinosaurs

Scientists have approximated the potential variety of dinosaur species that existed throughout the three durations of the Mesozoic era to be 1,543–2,468 (Source). As previously mentioned, paleontologists calculation that roughly 65% to be herbivores, and also 35% to be carnivores. The omnivore dinosaurs were a little fraction, around 1%-2%. Looking in ~ the estimation the there space over 2000 dinosaur species, 1-2% is 20-40 omnivore dinosaurs uncovered or however to it is in found. 

Here is a picture of several of the omnivorous dinosaurs the paleontologists have studied. In the first column, i list the dinosaur. In the second column, I suggest if it was Orinthomimosaur, Troodant, or Oviraptorosaur. In the 3rd column, ns shortly describe it.

More about Omnivorous Dinosaurs and also Some additional Facts

Determining any animal’s diet is a puzzle that scientists must put together by assessing habitats and also different parts of the creatures’ anatomy. As soon as it pertains to dinosaurs, paleontologists have actually only fossil evidence through fossilized remains and also need to make conclusions based upon those same measures – habitat, and anatomy. Let’s take it a look at part facts roughly this to fill the end the understanding of omnivore dinosaurs.

How do Paleontologists know a Dinosaur is an Omnivore and How do Scientists recognize A Dinosaur’s Diet?

A dinosaur’s diet is often established by analyzing their teeth or samples native its gut, depending on what is available. As a general rule, big herbivores like Brachiosaurus and also other sauropods had flat teeth, sort of like vegetation shredders. The shape of the this was broader and blunter contrasted to the teeth of carnivores prefer Allosaurus, i beg your pardon had more pointed, sharp this that they used in killing your prey.

Citipati fossils have actually been uncovered in Mongolia and also were one species of omnivore dinosaur –

However, there space some dinosaurs who teeth loss into the middle ground. If there are no samples obtainable of your gut to recognize their diet conclusively, they can be assumed to have consumed both plants and also animals, or be omnivorous.

Most dinosaurs have been established to it is in herbivorous, and this renders sense. The body size is likewise important, considering how much power is essential for the dinosaur to live. Once one eats tree material, that is closer come the main producers, which room plants, giving more energy than eating animals, further down the food chain.

There deserve to only it is in inferences acquired from the available evidence. Due to the fact that all we are studying space fossils the are numerous years old, us cannot however definitively say the all dinosaurs room strictly carnivores or herbivores.

There has actually been some evidence of a lengthy necked dinosaur that was predatory and also carnivorous in its earlier stages and also transitioned to becoming a herbivore once it thrived older. That is referred to as the Elaphrosaurus, a family member of the Tyrannosaurus rex and the Velociraptor. That is fossil was uncovered in Victoria, Australia.

Was Triceratops an Omnivore?

No, the Triceratops was no an omnivore. It was a herbivore, as inferred native its more comprehensive teeth perfect for mashing plant material. Fossil evidence points come its eating plants, bushes, and tiny trees the it knocked down v its horns and beak. It is many recognizable by its 3 horns and the broad frill about its neck.

Was Velociraptor an Omnivore? 

A bipedal dinosaur live 75 million year ago, well-known as Velociraptor. This dinosaur to be a speedster that had a running rate of more than 64 kilometers every hour. The debate around his nature is began weather Velociraptor to be an omnivore. Yet if us look at this speedster dinosaur’s skull anatomy, us will figure out what he was. They had a curved skull v two solid jaws. Each jaw had actually a strong and spicy 28 teeth.

Additionally, they had actually tree claws each on both front hands to flesh the end their prey. By this anatomy, we deserve to understand they to be not just carnivores but also the predators. So, it is clear that Velociraptor was no an omnivore. 

Deinocherus to be the best omnivorous dinosaur and from that is fossil remains, the arms to be as lengthy as one average-sized guy –

Final Thoughts

There is tho so much to learn about the prehistoric citizens of ours earth! it is fascinating how dinosaurs lived and also interacted through their environment. Every year, scientists and paleontologists come find new fossils and continue study to additional our understanding of dinosaurs that lived millions of years ago. 

When it pertains to determining the form of omnivore dinosaurs that lived and what they ate, we are beginning to gain a better picture based on fossil findings. The a certain thing that there will be more surprises to come as we uncover an ext fossils. Who knows, possibly we will uncover out even more facts about how omnivore dinosaurs lived and ate.
