Why the ancient predators were the huge heads?

it looked like garinii according to the artist
Millions of years ago, our planet was inhabited by the most unusual animals, the existence of which many of us do not even know. For example, recently on the territory of modern Argentina was found , which had two hind legs. That's nothing — but what you say about the fact that before the appearance of dinosaurs on Earth lived lizards with huge heads, which nobody ventured to hunt? They belonged to the genus of reptiles animals called garinii and currently scientists know only two species. One of them was already well understood, but the second still remained something unknown. Recently, scientists finally managed to study in detail their structure and to make very interesting conclusions.
Unusual animals with huge heads appeared after the so-called 252 million years ago. During one of the largest natural disasters killed more than 96% of marine animals and 73% of terrestrial vertebrates. However, after the planet is overrun by a completely different species of animals, among which was the aforementioned garinii — superchinese, who occupied the highest place in the food chain of that time.
the Most dangerous predators of ancient times
The fossil remains of a species called Garjainia prima was found by scientists on the territory of South Africa. Judging by the dug up bones, body length of ancient predators was about three meters. The most unusual part of their body was the head, the size of which almost match the size of the rest of the body. According to paleontologists, ancient pangolins are one of a kind, because the comparison of their bones with skeletons of modern mammals 89 41 dinosaur revealed nothing in common in terms of this ratio, body size and head.
Carnivorous lizards lived before the time of dinosaurs
In Addition to South Africa, bones of ancient predators, with a huge head was also found on the territory of Russia. Paleontologists gave the new species of lizards name Vjushkovia triplicostata, but for a long time could not identify the differences between two species of creatures. It turned out, they are almost there — the exception is the presence of Russian dinosaurs tiny teeth on the upper part of the oral cavity. Scientists were fairly difficult to discover them due to the fact that the teeth are rarely preserved for hundreds of millions of years.
Based on the lack of obvious differences between the two skeletons, scientists have concluded that the found in Africa and Russia the remains belong to one and the same species of animals. Initially, they assumed that the giant head could stop them from going, but this theory was quickly rejected. Now researchers believe that the huge jaws of animals help them to greatly compress their victims in the teeth and eat them. Perhaps it is because of the large head ancient animals and was able to get to the top of the food chain and have less enemies able to attack them.
According to the newspaper , currently work on the study of some of the most dangerous animals in the stories are not completed. According to Professor Richard Butler, they are trying to study the muscle location on the body of the predators. With the new discoveries they want to make sure that ancient reptiles were really able to keep up with such a massive head.
