Pliosaurus Vs Plesiosaurus.

Pliosaurus and Plesiosaurus are two distinct genera of the same family or order of marine reptiles that lived in prehistoric times. Now there are few giant marine reptiles, arguably the most important the marine crocodile with more than 6 feet long, but that was nothing compared with the members of these two genres that were true sea monsters. Here are some.


They were usually large predators with large jaws and well armed, short necks. Some examples are:

Kronosaurus A marine reptile which, like other Pliosaurus, had short necks but strong. Their jaws measured 2.5 meters long fang-filled and the length of his body could be up to 12 feet and weigh 15 tons. Some call it the Rex Marine.

Liopleurodon was another Pliosaurus but with their own families, the Liopleurodon was a great swimmer, a lively marine predator,
with a shape similar to but even larger Kronosaurus. Grow to 27 meters and weigh 150 tons, was able to pursue quickly and for long periods at their prey. With jaws 3 meters long and with teeth to tear to twice as long as those of a Tyrannosaurus Rex. (30 cm long)

PREDATOR X. A curious name for
an animal surprising. It is believed that X was a Liopleurodon Predator, a large skull and huge jaws, its dimensions were similar, maybe a little smaller: a 3-meter jaw full of teeth over 30 cm long and it is
believed, was an animal that had more bite force among all known.


Large predator fish from four large fins and long necks characteristic of animal facilitated its kind that raises its head to breathe. The best known are:

Elasmosaurus. About 15 meters long, which were 8 meters long neck and the rest is for your body. With a weight of 9 tons, was a heavyweight of the oceans of the Cretaceous. And although it was stylized and rather graceful, was a super-predator of the time. Although he was no match with any of the three Pliosaurus we've seen (like the Predator X Kronosaurus or who were his rivals and could live at the time)

NOTHOSAURUS. Another known Plesiosaurus, possibly one of the first of its kind. Not exactly a Plesiosaurus, but was (or any of its branch) who gave birth to this genre. It was "little" about 4 meters long and less than a ton. With strong long teeth that bite and to catch fish served with a quick bite.

CRYPTOCLIDUS. Possibly the second most popular after Elasmosaurus Plesiosaurus. Was over 8 meters long and weighed 8 tons. His neck, long as all Plesiosaurus was more robust than others, however its elasticity was lower. This being a predator rather Bland. Hunted large prey and not be satisfied with simple and small dams. However, it was an animal whose size had very few enemies.

Now, after the abstract, let's see some videos:

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.

Brontornis burmeisteri

A fearsome carnivorous birds and greatest of all time was the Brontornis burmeisteri. A flightless bird belonging to the subfamily Brontornithinae, which rivals the size of titanium-prehistoric other birds such as the family of Phorusrhacidae (known as "Terror Bird") or other more current and Dromornis (known as the "elephant bird").

The Brontornis burmeisteri was first introduced in the subfamily of "Terror Bird" and it is because their physical characteristics were similar for its large size and predatory lifestyle, and more specifically introduced in the subfamily Brontornithinae that contained very large and stout forms.

Had a height of almost 3 meters and its weight could reach 500 kg. He had some strong legs, able to tear the skins of their prey with a single blow. To get an idea: we can look at the Cassowary bird-like prehistoric currently living in Australia and New Guinea and is able to kill people with their claws. It measures half a burmeisteri Brontornis and herbivore.
The prehistoric bird lived in what is now called the Patagonia (South America). Due to the volume, is likely to have a lifestyle between an ambush predator and prey actively chasing, jumping on her and shot down by the strike force after a short chase.
Was the dominant carnivore during the Miocene Patagonia, being able to kill even large animals like elephants and the predator Thylacosmilus Astrapotherium (a saber-toothed marsupial).

Simply fascinating.
