Top 10 Terrifying Prehistoric Sea Monsters
Velociraptor (ve·loc·i·rap·tor) (Swift seizer or thief) was a small carnivorous dinosaur, well known thanks to Jurassic Park. It was one of the smaller dromaeosaurs, smaller than Utahraptor and Deinonychus, and was about 2 meters long. It lived in Mongolia and China during the Late Cretaceous, 75 to 71 million years ago. Fossils found in show that Velociraptor had long feathers on its. Velociraptors are a group of extinct dinosaurs that lived approximately 70 – 75 million years ago. They measured nearly 7 ft. long, but stood just ft. tall at the hip. Of course, because they have been extinct for millions of years, this is all speculation.

We ask "How did dinosaurs become extinct? Dinosaurs became extinct about 65 million years ago at the end of the cretaceous period see what cretaceous dinosaurs were around at this time. Having existed for million years, why did dinosaurs die out? There are many different theories about why this happened.
Hoa will probably never know exactly extinxt happened, which means that scientists will continue to disagree and come up with different dinosaur extinction theories. Here are some of them: Asteroid Impact A massive asteroid hit the velociraptkrs at Chicxulub on the Yucatan Peninsula in Mexico about 65 million years. How long have velociraptors been extinct meteor crater is km from rim to rim and scientists have worked out that the asteroid must have been 10 km across.
It is thought that the impact would have caused massive damage, including a giant dust cloud which lead to massive changes in the climate. This would have destroyed lots of the cretaceous plantsso herbivorous dinosaurs starved and the meat eating ones were left with nothing to eat either. Ice Hwo Theory Now and again, the earth cools into periods we call ice ages. As dinosaurs were thought to be cold blooded, it would have been hard for them to cope with such cold conditions. For example, if large parts of the planet were covered in ice, then there would have been little or no plants for herbivorous dinos to eat.
However, there is no real evidence of an ice age at this time. Volcano Theory There was massive volcanic activity between 63 and 67 million years ago, particularly on the Deccan Plateau in western Haave. This, again, would have how long have velociraptors been extinct a massive change in climate, which dinosaurs would have found hard to adapt to.
Disease It is possible that a disease spread through the dinosaur population causing their extinction. Competition from Other Animals Fossils of small mammals have been found from 65 million years ago. It is possible that these small cretaceous animals started to compete with dinosaurs, for example stealing and eating dinosaur eggs.
However, no-one is sure whether mammals caused dinosaur extinction, or they thrived because dinosaurs were no longer around. Gradual Extinction The number of dinos declined throughout the cretaceous period. Maybe a number of factors contributed to their eventual extinction and they just died out. Dinosaur extinction is a big mystery, as although dinosaurs died out at this time, many species survived, including similar animal types like crocodiles.
New Discoveries Scientist have come up with some strange ideas but none of the how to find maiden names on ancestry.com really explains everything, so we will probably never be sure what happened. To help you keep up with the news and discoveries about this, I have set up a news page on Why are Dinosaurs Extinct? So what do you think?
Have you got a theory? Why not invent a story about how you think dinos became extinct and what is an exemption trust it with us here at Kids-dinosaurs. You can even upload a drawing to go with it!

Interesting Facts About the Velociraptor
Jun 18, · It was a “mere” 30 feet long and the longest teeth in its massive mouth were up to 11 inches long. This is why it was named after Cronus, the king of the old Greek buylevitraonline.co where it lived? If you guessed “Australia”, then you have been paying attention to life (and are correct). The head was up to 9 feet long. Utahraptor (meaning "Utah's predator") is a genus of large dromaeosaurid dinosaur that lived in North America during the Early Cretaceous buylevitraonline.co was a heavy-built, ground-dwelling, bipedal buylevitraonline.co contains a single species, Utahraptor ostrommaysi, which is the largest-known member of the family Dromaeosauridae. This, again, would have caused a massive change in climate, which dinosaurs would have found hard to adapt to. Disease It is possible that a disease spread through the dinosaur population causing their extinction. Competition from Other Animals Fossils of small mammals have been found from .
Gary Larson framed the issue best in a famous Far Side cartoon. A Stegosaurus behind a podium addresses an audience of his fellow dinosaurs: "The picture's pretty bleak, gentlemen For over a century, that quote has pretty much summed up popular and even professional opinions about dinosaur intelligence. It didn't help that one of the earliest dinosaurs to be discovered and classified. If only they'd been smarter, we like to think, some of them might have found a way to survive!
Since there's no way to travel back in time and give an Iguanodon an IQ test, naturalists have developed an indirect means of evaluating the intelligence of extinct animals. The Encephalization Quotient, or EQ, measures the size of a creature's brain against the size of the rest of its body and compares this ratio to that of other species of roughly the same size. Part of what makes us human beings smart is the enormous size of our brains compared to our bodies; our EQ measures a hefty 5.
That may not seem like such a big number, so let's look at the EQs of some other mammals: on this scale, wildebeests weigh in at. As you might expect, monkeys have higher EQs: 1. Dolphins are the only animals on the planet with EQs even close to those of humans; the bottlenose comes in at 3.
As you might expect, the EQs of dinosaurs are spread across the lower end of the spectrum. Triceratops weighs in at a scant. One of the trickiest aspects of animal intelligence is that, as a rule, a creature only has to be smart enough to prosper in its given ecosystem and avoid being eaten.
Since plant-eating sauropods and titanosaurs were so massively dumb, the predators that fed on them only needed to be marginally smarter, and most of the relative increase in the brain size of these carnivores can be attributed to their need for better smell, vision and muscular coordination, their tools for the hunt. However, it's possible to swing the pendulum too far in the other direction and exaggerate the intelligence of carnivorous dinosaurs.
For example, the doorknob-turning, pack-hunting Velociraptors of Jurassic Park and Jurassic World are a complete fantasy; if you met a live Velociraptor today, it would probably strike you as slightly dumber than a chicken. You certainly wouldn't be able to teach it tricks, since its EQ would be an order of magnitude below that of a dog or cat.
It's easy, from our present-day perspective, to poke fun at the walnut-brained dinosaurs that lived tens of millions of years ago. However, you should bear in mind that the proto-humans of five or six million years ago weren't exactly Einsteins, either; even though, as stated above, they were significantly smarter than the other mammals in their savannah ecosystems.
In other words, if you managed to time-transport a five-year-old Neanderthal into the present day, she probably wouldn't do very well in kindergarten! Dale Russell, the one-time curator of vertebrate fossils at the National Museum of Canada, once caused a stir with his speculation that Troodon might eventually have evolved a human-sized level of intelligence if it had been left to evolve for another few million years. It should be noted that Russell didn't propose this as a serious theory, which will come as a disappointment to those who still believe intelligent "reptoids" live among us.
