The Platybelodon, an ancestor of the elephant.

The Platybelodon was one of the ancestors that gave rise to modern elephants, though not unique, but so is the strangest appearance.

The Platybelodon was herbivorous, and like the current hippos, spent much time in the swamp water where they feed on aquatic plants. One of the most curious features of this animal from the Miocene was his two bottom teeth shovel-shaped. Two teeth were disproportionately long and wide, however, the teeth (protruding into the mammoths, mastodons and elephants) were small and insignificant.
Another use of these teeth is lower than was to grab the trunk and branches, serrated rubbing against the lower teeth to cut the tree.

Robust and heavy as a small elephant, it can weigh over a ton and a half and could grow to 2 meters high. As I said before, lived during the Miocene, from 15-4 million years, and lived in Africa, Europe, Asia and North America. Although it thrived during his time, did not survive beyond the Miocene. Although no one knows exactly why he died.
In any case, this curious animal, this ancestor of the elephant, the mastodon or mammoth, is an example of the diversity and richness of fauna in prehistoric times.


The Andrewsarchus or Androsarcus, was considered the largest carnivorous mammal history, but that position was occupied not alone. Along with this there is another giant carnivorous mammal, called Megistotherium (and some experts say it could even be larger than the Andrewsarchus). The Megistotherium was a terrible predator, a predator who struck fear Miocene to the titanic mastodons (found fossilized bones of mastodons with Megistotherium marks indicating that hunting for food).
The Megistotherium belonged to the family of Hyaenodontidae, a family of large predators, strong, aggressive and courageous. Predators that were in the top of the food chain before the mega saber-toothed cats like, or the greatest, the cave lion.
The Megistotherium lived in what is now Europe, Africa and Asia. As large as the current bison, weigh up to 1500 kg (3300 lb) and a height to the shoulders of more than 1.5 meters long and 3.5 (a white bear almost never reaches 1000 kg (2200 lb) and is 2.5 meters long). The dimensions of the skull were Megistotherium up to 1 meter long (similar to Androsarcus) and his jaw with a force of enormous pressure, harbored very powerful teeth can grind the hardest parts of prey such as bones or hooves. Do not forget that the family is synonymous Hyaenodontidae hyena's tooth, and these (the hyenas) are known for the strength of their jaws and teeth trituratodo. To get an idea, your name, Megistotherium, means "the biggest beast crushed bones."


That discovery! The cousin of the Tyrannosaurus Rex. A new tyrant among the dinosaurs of the Late Cretaceous (between 99 and 65 million years ago), a great beast, a new predator found, their fossils, currently Zhucheng in Shandong Province (east China). Therefore, it has been dubbed the Zhucheng Tyrant.

Tyrant could describe as a Tyrannosaurus Rex Zhucheng but a little smaller. For example:

The Tyrannosaurus was approximately 14 m in length, of Zhuncheng reached 11 meters. Negligible size, we ... that if you look down the street ... .... .... you make it over (not I think of another expression).

A little lower and also weighing less. T. Rex weighed about 6 tons, however, the Zhucheng weighed 4 tons.

Still, the new finding corresponds to a terrible carnivore with a powerful jaw, small arms like the Tyrannosaurus Rex. Possibly, like the T. Rex, Zhucheng could have been predator but a scavenger.

Anyway, so far are some fossils have been found from this dinosaur, a few vertebrae and mandible (with teeth certainly unique, larger in proportion to his jaw in the T. Rex). See if you still discovering more fossils and they can illustrate.


The Gigantoraptor is half bird, half dinosaur, not known, but what is .... is that it is a mystery.

Discovered in 2005 in the Gobi desert, lived 80 million years ago in the land of the Cretaceous period.
Its resemblance to the birds include anatomical features such as a peak instead of teeth in the jaws and the possibility of being covered with feathers. That's why we think it is the largest winged animal that has never existed. Whether flying or not.

Another question that appears on this prehistoric animal, half dinosaur, half bird, is your diet: it is thought that it was herbivorous, but on the other hand, has strong claws and is regarded as agile and fast moving, predatory characteristics. In short, we'll know later.

But how long the Gigantoraptor? For their measurements are 5 meters (17ft) tall to 8 meters (26ft) long and weighing about 2 tonnes. Oviraptoridae family, is the oldest. The Oviraptoridae are a group of dinosaurs known to include many feathered species. Gigantoraptor was much larger, about 35 times larger than its likely close relative, Caudipteryx.

The famous Bear-dog or Amphicyon

Imagine the world's largest wolf, and now doubling in size, finally give steroids to duplicate the musculature. Throw in claws bigger than a grizzly with a strong legs to run and reach high speeds ... That leaves us? As a predator that existed from the mid-Oligocene and early Miocene. His name was Amphicyon ingens (dog ambiguous) or commonly known as Bear-dog.
This prehistoric beast could be up to three meters and weigh up to 400 kg. Given its size, you might think was not very fast, but do not be fooled, it is thought that hunted their prey in ambush and surprised with a quick career. The smell was due to an as refined as a bloodhound and a fine ear. Type of game similar to the great bears today. He could hunt animals as robust as the old giant sloths or rhinos.

He lived in Europe and Asia and later introduced in North America by the Bering Strait (humans migrated from Asia to the Americas through the strait, possibly taking advantage of a glacial period and the freezing of the Sea) competition in North America other carnivorous even more ... the Daeodon or "terrible pig."

Hyena giant or Pachycrocuta Brevirostris.

Famous is the force that have the jaws of the hyenas that can reach pressures of 350 kg (600lb)and teeth grinding of hard bones and teeth and hooves. Well, now imagine a hyena twice as big, twice as strong and a powerful jaw twice ... this animal there was Pachycrocuta brevirostris.

Pachycrocuta a genus of prehistoric hyenas. The largest specimen, well-documented part of the species of giant hyenas Pachycrocuta brevirostris. With a height of 1 meter (39 in) and weigh up to 120 kg (250 lb).Un similar in size to a small lioness.
This size would make it the largest of the hyenas that have ever lived. He lived from the Middle Pliocene and Middle Pleistocene, about 3 million and 500,000 years ago.
Found fossils in Eurasia and southern and eastern Africa. In dens, caves used as dens.
Scavenger and a predator could be stubborn and tenacious to deer hunting big and small package was probably a hunter of large animals (up to larger deer and occasionally as Megaloceros). The chance of a scavenger is sensed it was a very big animal not built for chasing prey over long distances. In this aspect would have differed from today spotted hyena, which is a more agile animal that, contrary to his image of the documentaries, also kills his own food. Apparently it was ecologically close enough to the smaller (but still important) in relation perrieri Pliocrocuta never found as fossils contemporaries in the same region.

This is a very beautiful reconstruction extracted


The size of a large dog, this therapsid (reptile-like mammals) was a terrifying predator of the prehistoric period. He lived in the Triassic and Lower Jurassic (made between 245 and 208 million years ago) in what is now South Africa, Argentina, China and Antarctica. It was one of the most impressive land predators of its time.
Praising Cynognathus fossilized skulls of openings have been observed at the height of the snout, typical skulls of mammals, where vessels and nerves pass supplying the whiskers, similar to cats and dogs. So you think you had hair, and that these particular should serve as sensory organs.
With almost two meters long (6.3 ft counting the tail) and a head of 30 cm (1.0 ft) with wide jaws and sharp teeth, its bite was strong and had to exert great pressure (similar to today's crocodiles with 2500 kg of pressure.
The Cynognathus was an agile runner and can reach a speed of 35 km / h. .. conclusion was a very effective and powerful carnivore.

Colossochelys atlas or Testudo atlas

Testudo atlas or Colosoqueli, was the largest turtle. It was, to get a great idea to double that giant tortoises that live today. Reached 2.5 m in length, a height of 1.5 meters and 4 tons.
His legs, like an elephant, were projected on the sides of the body and held the heavy shell of the back. The almoahadillas in the soles of his feet compact distribute the great weight among the five fingers of each leg, with robust claws. It was probably herbivorous and their relatives today. Faced with danger, could get his head and legs in heavy bony armor to protect themselves.
Testudo atlas or Colosoqueli lived in South Asia more than a million years, Pleistocene.

In this video you can see a current Giant Tortoise. It should be intoaccount the Testudo Atlas, could weigh up to more than 15 times its weight.

Curiosity: Although the Testudo atlas or Colosoqueli is the largest turtle that ever lived, not the animal that has existed more shell. This would be the Arquelón 3.7 meters long. This is a sea turtle extinct.

Giant deer or Megaloceros

The Irish elk, Giant deer Megaloceros deer is the largest in history. Like a large deer, his antlers were up to 3.5 m from tip to tip. Although he lived in Europe and much of Asia for half a million years to extinction in recent times, often known as "Irish elk" for the abundant findings of specimens preserved in the peat bogs of Ireland.
The giant deer reached a height of 2.2 m to the cross in the case of males, significantly higher than the largest of the moose. It was a species with strong sexual dimorphism, as females were significantly smaller and slender than the males, in addition to lacking an impressive antlers.
The giant deer grazers were animals that thrived on abundant grass and shrubs in the large, cold plains covering much of Eurasia during the Pleistocene.
Antlers were so large that it required large amounts of calcium and phosphate to form occurring cases of osteoporosis among male Irish elk, so that mortality, already high, increased in bad years.
This fantastic animal became extinct only 7000 years. Were extinguished by changes in the field that were caused by early Neolithic farmers Russian.

Andrewsarchus or "androsarcus"

The Andrewsarchus is related to the sheep and goat, but has wolf's clothing. Mmífero was a giant of the time. It has a meter jaws, and scavenger. They lived in the late Eocene.
He walked on four short legs and a long body, long tail, and feet with hoofed toes. He had a long snout with large, sharp teeth and flat teeth may have been used to crush bones.
Had a length from snout to the back of the pelvis of about 3.4 m and a height from the ground to the shoulder or mid-back of approximately 1.5 m. Probably weighed about 1000 kg
Your diet may have been more carnivorous and omnivorous that is not yet clear whether he was a hunter or scavenger, because the teeth are more characteristic of a scavenger with teeth grinding.
He is considered the largest known terrestrial carnivore to date.


The Therizinosaurus was a bipedal animal with vicious prehistoric claws was found in Mongolia (Asia)
THE Therizinosaurus measuring up to 12 m long. His weight was up to 6 tons. The total arm measured 2.5 meters long, and his only scythe-shaped claw measuring 70 centimeters in outer curve. That length does not include the horny covering that must have surrounded the claw, with which it could reach up to 1 meter long.

Therizinosaurus ( "scythe lizard") lived in the Cretaceous (for about 70 to 65 million years in the Maastrichtian).

He lived together with other prehistoric animals like the striking resemblance and Erlikosaurus Segnosaurus.

Are unknown Therizinosaurus eating habits. These are unknown as fossils found in was not found remains that may determine your diet. He may have been herbivorous although the claws may be possessed for the struggle to defend territory or to mate, even to defend themselves from predators like the Tarbosaurus.


Megalosaurus was a predator of some up to 10 meters long and weighing 1 t. He lived in what is now Europe, America, Asia and Africa during the Jurassic period, 181 made 169 million years.
Among their prizes were sauropods, large prehistoric animals and stegosaurs and mammals.
Besides being a fast predator, with speeds that could reach 40 km / h thanks to its well-balanced structure, the Megalosaurus also got their food scavenging.
The Megalosaurus was one of the first dinosaur discoveries, England 1818. At that time, and seeing the fossils found, these bones were so enormous that gave its name Megalosaurus (great lizard).
The jaw of Megalosaurus had teeth long and curved, strongly subject to the gums to avoid losing in the struggle. The teeth were sharp with the corrugated edge that worked like a saw. Ripping a more efficient prey.
To make matters worse, had prehistoric animal with sharp claws and tear that held the hard skin of the victims.


To be a Velociraptor dromaeosaurid was relatively small, the adults reach a length of 2 m, and approximately 0.5 meters in height at the hip, and weighing about 15 kg. The skull, about 25 cm long, was uniquely up-curved, with a concave upper surface and a convex bottom. The jaws were lined with 26 or 28 teeth on each side, the rear edge of each tooth was markedly serrated.
But of all the features that made the Velociraptor a murderer efficient and sharp curved claws were the most dangerous. Located on the second toe of each foot, these claws were a fine point and were flattened laterally, like the claws of a cat. When the Velociraptor ran, stretched claws held back so as not touching the ground and did not lose their edge.
When the Velociraptor attack, the claw could project forward and down while HADB a strong kick. Thus, the claw could act as a razor-sharp knife and result in protracted and deep cuts in their prey, probably bleed to death.
Velociraptor is well known in his role as a cruel and cunning murderer may attack small offspring from larger dinosaurs such as Triceratops.

Velociraptor (meaning "swift thief") in Castilian Velociraptor, is a dromaeosaurid theropod dinosaur that lived during the Campanian to the late Cretaceous period, makes about 70 to 65 million years. On the mainland, which is in Europe and Asia.


Gerrothorax is an extinct genus of amphibian temnospondyl who lived in the late Triassic period (about 210 million years ago) in what is now Germany and Greenland. Reached an approximate length of 1 meter. Their bodies are flattened, suggesting they were hiding under the sand or mud at the bottom of rivers and lakes as potential victims stalked her large eyes focused upward. The skull had a peculiar way with angular protrusions on both sides. This geometry of the skull is reminiscent of the genus Diplocaulus, but less developed.

Fossils show that the species of this genus were pedomórficas, keeping three pairs of gills also in the adult stage, which allowed them to breathe underwater. This feature also found in some current caudate, as in certain species of the family and Ambystomatidae Mudpuppy.

Curiosity: The lower jaw was fixed Gerrothorax and chewing had to raise his head and drop it. That is, exactly the opposite of what we do and almost all the animals of creation.


Hyracotherium (beast like a Hyrax), also known as Eohippus, is a genus of mammal Perissodactyla Palaeotheriidae family.

It is considered an ancestor of the horse, rhinoceros and tapir. It is a quadruped animal that lived in the Northern Hemisphere (Asia, Europe and North America) during the Eocene period, makes 60 to 45 million years. The line to the existing horse evolució through the following animals Preistorica: Oligohippus, Merichippus, Pliohippus. In chronological order.

Hyracotherium was a small herbivore the size of a fox, media cross about 35 inches and weighed 6 kg, had four toes on the forefeet and three on hind paws protected, the central one being longer. These animals were already clearly like the horse, despite its small size and probably lived in forests browsing. His teeth were adapted for the consumption of young leaves of the bushes and his eyes were different from modern horses as they were located more to the center of the head preventing a good side vision (which in the modern horse serves as defensive system), Eohippus but did not need because in the jungle environment in which they lived, was more effective camouflage to avoid predators.


The entelodont is an extinct family of hoofed mammals related to the current pig and animals with hooves. Distributed in Asia and North America made between 45 and 25 million years. Measured about 2,1 m (7 feet) high, 3 `5 meters (14 feet)long and had a brain the size of a fist. It fed on carrion, oportunisatas, and plants. Not rule out the flush of live prey. Your lifestyle should look like pigs. Believed to be a omnivore because their teeth had large teeth and powerful back teeth. Like the pigs had a heavy body and short legs and a robust and thin.
With a size similar to Hyaenodon and weighing about 4,207 kg (9,300 lb) was the only rival of Hyaenodon.
For the morphological differences between male and female remains, it is believed that males were competing to win the group severamete females.


Velociraptor was a prehistoric animal measuring up to 2.07 m (6.8 ft) long, 0.5 m (1.6 ft) high at the hip, and weighing up to 15 kg (33 lb). The skull, which grew up to 25 cm (9.8 in) long, was uniquely up-curved, concave on the upper surface and convex on the lower. The jaws were lined with 26–28 widely spaced teeth on each side, each more strongly serrated on the back edge than the front—possibly an adaptation that improved its ability to catch and hold fast-moving prey.

Velociraptor, like other dromaeosaurids, had a large manus ('hand') with three strongly curved claws, which were similar in construction and flexibility to the wing bones of modern birds. The second digit was the longest of the three digits present, while the first was shortest. The structure of the carpal (wrist) bones prevented pronation of the wrist and forced the 'hands' to be held with the palmar surface facing inwards (medially), not downwards. However, whereas most theropods had feet with three digits contacting the ground, dromaeosaurids like Velociraptor walked on only their third and fourth digits. The second digit, for which Velociraptor is most famous, was highly modified and held retracted off of the ground. It bore a relatively large, sickle-shaped claw, typical of dromaeosaurid and troodontid dinosaurs. This enlarged claw, which could be over 6.5 cm (2.6 in) long around its outer edge, was most likely a predatory device used to tear into prey, possibly delivering a fatal blow.

Velociraptor (meaning 'swift seizer') is a genus of dromaeosaurid theropod dinosaur that existed approximately 75 to 71 mya (million years ago) during the later part of the Cretaceous Period. Only two species are currently recognized, although others have been assigned in the past. The type species is V. mongoliensis; fossils of this species have been discovered in both Inner and Outer Mongolia in central Asia. A second species, V. osmolskae, was named in 2008 for skull material from Inner Mongolia.

In 2007, paleontologists reported the discovery of quill knobs on a well-preserved Velociraptor mongoliensis forearm from Mongolia, confirming the presence of feathers in this species
