Herbivore

1/1
Achelousaurus

Adult Achelousaurus had rough bosses (roundish protuberances) above the eyes and on the snout where other centrosaurines often had horns in the same position.

1/1
Ankylosaurus

Ankylosaurus was the largest member of its family.

1/1
Aurochs

An extinct species of large wild cattle that inhabited Asia, Europe, and North Africa. It is the ancestor of domestic cattle. The species survived in Europe until 1627, when the last recorded aurochs died in the Jaktorów Forest, Poland.

1/1
Beipiaosaurus

Before the discovery of Yutyrannus, they were among the largest dinosaurs known from direct evidence to be feathered.

1/1
Coelodonta

Coelodonta= from the Greek mean "hollow tooth", in reference to the deep grooves of their molars.

1/1
Diprotodon

The largest known marsupial to have ever existed.

1/1
Euoplocephalus

Among the ankylosaurids, Euoplocephalus was exceeded in size only by Ankylosaurus.

1/1
Hypsilophodon

Like most small dinosaurs, Hypsilophodon was bipedal: it ran on two legs. Its entire body was built for running. A light-weight, minimized skeleton, low, aerodynamic posture, long legs and stiff tail, immobilised by ossified tendons, for balance: all would have allowed it to travel remarkably fast for its size. 

1/1
Lambeosaurus

Notable for the hatchet-shaped hollow bony crest on top of its skull.

1/1
Mammoth

Woolly mammoth (M. primigenius) was the last species of the genus.

1/1
Megalochelys Atlas

An extinct species of giant cryptodiran tortoise.

1/1
Nodosaurus

It is thought that without a club on its tail, Nodosaurus would have been left without much in terms of active defenses. When threatened, it probably dropped to the ground so that only its armored back and sides were exposed, much like modern-day hedgehogs.

1/1
Pachyrhinosaurus

Instead of horns, their skulls bore massive, flattened bosses; a large boss over the nose and a smaller one over the eyes.

1/1
Parasaurolophus

Well-developed arms and strong legs.

1/1
Protoceratops

Member of the group of early horned dinosaur, however, it was much smaller creature that lacked well-developed horns and retained some basal traits not seen in later genera.

1/1
Savannasaurus

A medium-sized titanosaur.

1/1
Stegoceras

Stegoceras was the first pachycephalosaur to be described.

1/1
Tenontosaurus

Large size long tail herds strength speed senses head

1/1
Titanosaurus

Often depicted as a burly sauropod but with a thicker, broader neck and shorter tail.

1/1
Uintatherium

Its most unusual feature was the skull, which is both large and strongly built, but simultaneously flat and concave: this feature is rare and, apart from some brontotheres, not regularly characteristic of any other known mammal.

1/1
Alamosaurus

A gigantic quadrupedal herbivore with along neck and tail and relatively long limbs.

1/1
Apatosaurus

Less elongated and more heavily constructed than those of Diplodocus.

1/1
Bactrosaurus

It was an early relative of Lambeosaurus, and shows a number of iguanodont-like features, including three stacked teeth for each visible tooth, small maxillary teeth, and an unusually powerful build for a hadrosaur.

1/1
Brachiosaurus

It have long forelimbs and upward sloping backbone to support the neck.

1/1
Corythosaurus

Corythosaurus is known from many skulls with tall crests. The crests resemble the crests of the cassowary and a Corinthian helmet.

1/1
Dracorex

The name Dracorex means “dragon king” and the only known species of Dracorex is named “hogwartsia” in honor of the Hogwart’s school from the Harry Potter series of novels.

1/1
Homalocephale

The discovery of unusually wide hips leading some paleontologists to believe that the dinosaur gave birth to live young, unlike many dinosaurs that lay eggs.

1/1
Iguanodon

Large thumb spikes used for defense against predators.

1/1
Macrauchenia

Macrauchenia had a somewhat camel-like body, with sturdy legs, a long neck and a relatively small head. Its feet, however, more closely resembled those of a modern rhinoceros, with one central toe and two side toes on each foot.

1/1
Massospondylus

Massospondylus was one amongst the first dinosaurs to be named with a taxonomic history going back as far as the mid nineteenth century.‭

1/1
Microceratus

It walked on two legs, had short front arms, a characteristic ceratopsian frill and beak-like mouth.

1/1
Omeisaurus

O. tianfuensis had the longest neck of the genus with 9.1m long.

1/1
Panoplosaurus

It consists of the complete skull with lower jaws, the cervical vertebrae.

1/1
Plateosaurus

Plateosaurus were the first known large herbivores among the dinosaurs.

1/1
Psittacosaurus

The species were obligate bipeds at adulthood, with a high skull and a robust beak.

1/1
Sinornithomimus

Relatively short neck and head for a member of ornithomimid.

1/1
Stegosaurus

Tail tipped with spikes.

1/1
Thecodontosaurus

Thecodontosaurus also had a much shorter neck when compared to other prosauropodomorphs.

1/1
Triceratops

Bearing a large bony frill and three horns on the skull.

1/1
Yunnanosaurus

There were more than sixty spoon shaped teeth in the jaws of Yunnanosaurus, and were unique among prosauropods in that its teeth were self-sharpening because they “[wore] against each other as the animal fed.”

1/1
Amargasaurus

Some paleontologists have postulated that this dinosaur may have actually had a sail that grew out of its back. If it did, then it would have been used to make the dinosaur look better, for regulation of body temperature or maybe even used for mating rituals.

1/1
Archaeoceratops

It appears to have been bipedal and quite small with comparatively large head.

1/1
Bagaceratops

Although emerging late in the reign of the dinosaurs, Bagaceratops had a fairly primitive anatomy and kept the small body size that characterized early ceratopsians.

1/1
Brachylophosaurus

This animal is notable for its bony crest, which forms a flat, paddle-like plate over the top of the skull.

1/1
Diamantinasaurus

The only titanosauria to share a ventral keel set within a sharply defined depression under the dorsals.

1/1
Elasmotherium

Elasmotherium is thought to have had a keratinous horn, indicated by a circular dome on the forehead. There was likely a large hump of muscle on the back, which is generally thought to have supported a heavy horn.

1/1
Huayangosaurus

Most smallest and earliest stegosaurs.

1/1
Kentrosaurus

Could swing its tail spikes with skull-cracking speed.

1/1
Maiasaura

It had a small, spiky crest in front of its eyes. The crest may have been used in headbutting contests between males during the breeding season.

1/1
Megaloceros Giganteus

An extinct species of deer and is one of the largest deer that ever lived.

1/1
Moeritherium

These prehistoric mammals are related to the elephant and, more distantly, sea cows and hyraxes.

1/1
Pachycephalosaurus

It has the thickest skull among all dinosaur.

1/1
Paraceratherium

It is one of the largest terrestrial mammals that has existed and lived from the early to late Oligocene epoch. Because of its size, it would have had few predators and a slow rate of reproduction.

1/1
Polacanthus

Polacanthus was a medium-sized ankylosaur.

1/1
Qantassaurus

Its feet had claws for traction, and a long tail probably helped with turning, stiffened by ossified tendons.

1/1
Sivatherium

One of the largest giraffid known, and also one of the largest ruminants of all time.

1/1

It had four to six long parietal spikes extending from its neck frill.

1/1
