Ancient Animals That Dazzle

1. Deinocheirus
Ancient Animals That Dazzle | New

 The only fossils found from this dinosaur is a pair of arms and some parts of the spine. Deinocheirus chances are relatives of the ornithomimosaur, at least that's the contention by paleontologists.


He is a genus of large theropod dinosaur that lived in the late Cretaceous period and the population is scattered in southern Mongolia. His arm may be too long for his body and the claw hand it indicates that he is one of the deadly dinosaur.


But in fact, the usefulness of "arms" is still widely debated. Some researchers said the claw was used as the primary tool for hunting.


Several others said the claws were too blunt, so it is only used as a defensive weapon. There is even a suggestion that Deinocheirus using large arms to climb trees, although this hypothesis is widely ignored.


2. Diprotodon
Before the first man to set foot on the continent of Australia about 40,000 years ago, a wide range of large-sized marsupials once lived there. One of the largest is Diprotodon.


Marsupial is estimated that the size of an adult Hippo. Judging from the shape morphology, it looks much like a Wombat, the Australian marsupial species, but a giant.


Just like most other marsupial animals, Diprotodon also consume leaves as its main food. Although they are not animals who have nimble movements such as kangaroos, but the large size and strong body makes the predator is very difficult to defeated.


3. Moropus
When scientists find fossils Moropus for the first time, they seemed hard to believe the morphology of this particular creature. Ancient animal with a head like a horse's head actually has a weird body shape.


Scientists describe it as a "mixture" of the three animals, namely horses, pygmy giraffes and bears. Horse-like head and the body of a bear-like bodies connected by a fairly long neck giraffe neck dwarf tub.


With long nails sharp nan, as well as the ability to run well of course he has a good defense to avoid the threat of predators. Moropus live in the southern and western Asia about 12,000 years ago.

4. Ambulocetus
This is one of the ancient creatures that claimed many adherents of Neo-Darwinism as strong evidence of a period of transition to terrestrial species of sea creatures. Ambulocetus, ancient animals with similar stature mixture ancestors of whales and otters living in what is now known as modern Pakistan about 50 million years ago.


Ambulotecetus an adult body length is estimated about 12 feet. Form a large head with a long jaw. Sharp teeth designed to catch and gripping prey. In the water, he can move with the help of agile tail which is used as a "motor" for the body.
5. Lystrosaurus
Before the emergence of dinosaurs, living creature on Earth ever enlivened by some strange animal that resembles a reptile. One is Lystrosaurus.


Ancient animals is quite interesting because this strange body shape living in swampy habitats, but it also does not matter if it should be forced to inhabit places classified as dry. Lystrosaurus estimated to inhabit the earth about 230 million years ago.

6. Phorusrhacos
About 20 million years ago, South America is a land that has so many variations of species of birds and mammals. One of them is fairly well known carnivorous bird species named Phorusrhacos.


He is a species of bird that can not fly. Height can reach 10 feet (3 meters). Although not able to fly, they are fast runners. This makes Phorusrhacos can easily catch their prey.


Phorusrhacos species estimated to exist until 3 million years ago. Scientists estimate Phorusrhacos extinction caused by the emergence of several other predators are migrating from north to south Amrika after the two connected by a land which appears to the Central American mainland.

7. Mammoth
I'm sure you guys are familiar with this one the legendary animal. Mammoth is one of the ancient animals that are so popular. Physically resembles an elephant but has a thick fur all over its body.


Great stature as well as additional "weapon" in the form of ivory that was so long makes it so difficult to conquer any predators. The paintings are the scratched on cave walls by early man many describe how difficult this animal to be conquered by them.


Mammoth is the animals that inhabit around Wrangel Island in the northern coast of Siberia. Many scientists believe, the last generation of Mammoth still can be found around 4000 years ago when construction of the pyramid of Khufu at Giza, Egypt have been completed.

8. Harimau Gigi Pedang
They are one of the animals of the ice age is so well known. One nan deadly vicious predator ever set foot on this earth. Tiger Tooth Sword inhabit the western United States at the end of the ice age, but they also are scattered in several other regions of North America and some remain in the South American region.


Known, there are 2 genus of this animal, namely Genus Genus Smilodon and Homotherium. In general, species of the genus Smilidon long fangs can reach more than 18 centimeters, while for Homotherium genus has about 10 centimeters long fangs. These animals hunt horses, bison, antelope as food.

9. Deinotherium
Deinotherium is one of the largest land mammals that ever set foot on Earth. Prehistoric creatures that live in times of middle Miocene to early Pleistocene in general has a high 3.5 to 4.5 meters (Deinotherium adult size) and weighing between 5-14 tons.


Deinotherium which is a close relative of the modern elephant yore live scattered in many parts of Asia, Africa, and Europe. Physical form is not much different from modern elephants, except that it has a shorter trunk and tusks are located in the lower jaw.


Ivory may be used as a tool to dig the ground to gain access to the roots and vegetables. Deinotherium genus has three species have been identified, and all have a large size. Species diataranya Deinotherium giganteus, Deinotherium indicum, and Deinotherium bozasi.

10. Therizinosauridae
Therizinosauridae is Theropoda Dinosaur family who lived in the late Cretaceous period (99.6 - 65.5 million years ago). Unlike most Theropoda which is a carnivore, herbivore Therizinosauridae is (although some of them are known as omnivores).


It should be underlined, Therizinosauridae is the name of a familia in scientific classification. The name was first used by Evgeny Maleev in 1954 to include Therizinosaurus cheloniformis (Theropoda type who still has a lot of the puzzle) into a familia along with Segnosaurus and Nothronychus.


Therizinosauridae families have eccentric physical shape. In general they have a long neck and feathers. Besides their claws are also quite large, there may be more than one meter in length.

11. Epidexipteryx
Epidexipteryx is a small genus of dinosaur maniraptorian. Prehistoric animals that live in China around 152-168 million years ago, this is one of the smallest dinosaurs ever.


Adult size only reaches 10 inches (about the size of a pigeon). One attraction of Epidexipteryx are four long feathers that grow on the tail.


Not like feathers that we usually encounter in class aves animals, structures like feathers on this Epidexipteryx like a sheet of tape that stands extends upward. However, due to lack of remiges (wing feathers) makes this animal can not fly.
12. Longisquama insignis
Living in the mid to late Triassic period (230-225 million years ago), Longisquama insignis an ancient lizard is so interesting because it has a series of "fur" long standing along his back.


Structure of the "fur" that is still a matter of debate among the researchers. Some researchers believe that the term structure that grows on the back Longisquama not the kind of fur, but scales which generally can be found in reptiles such as iguanas.


Difference scales on Lingisquama longer and shaped a bit awkward. However, in the opinion of paleontologists, N. Frasher in his book Dawn of the Dinosaurs: Life in the Triassic, elongated structure is not a part of his body.


This structure is the possibility of a kind of plant fern fossils come to be with him and then misinterpreted. Frasher opinion may be strengthened by the fact that fossilized structures found in some animals it often has nothing to do with the animal fossils.

13. Sharovipteryx


 
Sharovipteryx a living reptiles contemporaneous with Longisquama, which is in the mid to late Triassic. Ancient creature that has a body length of about eight inches with a weight of 7.5 grams is very unique because it has the size of a very wide rear legs than front legs.


The hind legs are so wide, coupled with a membrane that grows them make it as if it had wings with which to fly. Despite the fact that this animal was not able to fly like a bird, but by no means a stretch of the wing membrane in the legs become useless.


Recent study says thanks to the wing membranes, can be more nimble Sharovipteryx when sliding from one place to another due to its mechanism of action is very similar to the delta wing on a modern fighter aircraft.

Some researchers believe the animals may have a close relationship with pterosaurs remember meraka have the same flight membrane growing between his legs, although it is still very controversial.

14. Pterodaustro
Pterodaustro have a very long skull, which is about 29 cm. Snout dominates 85% of the total length of the skull. Another oddity is the physical form of an unusual set of teeth.


Teeth bottom jaw grows like thousands of fur seal that may he used as a tool to filter plankton, algae, and other small makhkluk of water.


Teeth are growing by the thousands in two long grooves parallel to the edge of the jaw. About 3 cm in length with a width between 0.2 - 0, 3 millimeters. This structure is not initially suspected tooth, but after some research the allegations eventually fade. The structure is really a normal tooth enamel because there, dentin and pulp.

15. Microraptor
The genus Microraptor is one of the ranks of small dinosaurs. They lived about 120 million years ago and the population is spread out in several regions of China. This type generally has four wings with an elongated tail.


Despite having two pairs of wings, Microraptor could not fly. Instead, he might just glide from one place to another like a flying squirrel.


Most among evolutionists consider this animal a transitional creature dinosaurs to birds, where the ability to develop into launching the flight system.


Some researchers argue, it is likely that many animals spend their lives in trees, referring to the fact that the wings of Microraptor hinder their ability to walk on land.

16. Amphicoelias fragillimus
This elusive fossil was discovered by famed paleontologist Edward Drinker Cope. Cope has found many prehistoric fossils, but this one is the most bizarre.


How could I not? only the odd fossil vertebrae are pieces that have long keseluruahan estimated 40-60 meters. If the size is really valid, it makes Amphicoelias fragillimus may be the longest and toughest creature ever (competing with blue whales and Argentinosaurus).


But once again, these fossils are still a lot of debate because of the difficulty to identify the discovery of fossils of a very-very minimal. Is this creature is the largest animal ever to walk the earth or just a misunderstanding and just a hoax.
