Scientists have discovered a plural of animals in Arizona’s Jovashim, including North America’s most famous flying crawling animals, which shows a time of transition when they were designed to eliminate the soon -to -be -ending hatred, with newcomers living in the early days of dinosaur.
Petersur’s remnants, almost a small seagel size, and other creatures were discovered in the Patfide Forest National Park, a place where the trays, including a large tree trunks, are known for producing plants and animals. The newly found Gavasam is 209 million years old and includes at least 16 versatile species, seven of them were unknown.
The Trusesk came to the heels of the largest large -scale landslide 252 million years ago, and then 201 million years ago, with another massive extinction, which wiped out many of the biggest rivals of dinosaur, which later achieved uncertainty in the Jurassic era. Both disasters were apparently caused by extreme volcanoes.
The volcanic ash -rich rock provides a snap shot of cross -crossing tropical ecosystem through rivers on the southern bank of a large desert.
Along with Petersur, the scene included other newcomers, including ancient frogs, lizard-like crawling animals and one of the leading turtles-they all resemble their relatives today. They were part of the largest meat eating and planting tissues in the ecosystem that were growing up at the time, but relatively relatively died soon.
Although the trial began during the dinosaur period, no dinosaur was found in this ecosystem, in which it was clear how they had not yet prevailed.
“Although dinosaurs are found in contemporary stones from Arizona and New Mexico, they were not part of the environmental system we are studying,” said Ben Cleigman, the National Museum of Natural History of the National Museum of Natural History in Washington.
“It’s strange, and may be preferred to live in another type of environment with dinosaurs,” Clegman added.
This ecosystem, called Panjia, was located just above the equator in the middle of the Super Contract, which later broke and gave birth to today’s continents.
The cousin of dinosaurs, Petrosaurus, was the first to achieve a power -powered flight, followed by birds and bats followed. It is believed that Petrosor appeared about 23 230 million years ago, at the same time was the early dinosaurs, though his oldest fossils are about 215 million years ago in Europe.
It is believed that the newly identified Petersor, named Utophradctoles Mac Intery, is believed to have hunting local rivers. Its partial skeleton contains a tooth -jaw, some extra isolated teeth and a part of its long finger bones, which helped form its arm equipment.
His wings was about three feet (one meter) and his skull was about four inches (10 cm) long. He had a curved fungus in the front of his mouth to catch the fish when he hunted in the back of the jaw, flying on teeth like rivers and blades. Researchers say utfradoxilles have the breath, as was done by all early Petrosor.
Etophradctilles means “Ash Wingd Dawn Devi”, which was to recognize the nature of the rock in which it was found and the status of species near the beginning of the Petrosor lineage. McIntry recognizes the Suzanne Mac Internet, who is about to prepare for the former Smithsonia, who detected it.
The turtle was a species of land life, while the animals that crawled like lizards were from the modern era of New Zealand. Some other crawling animals were also found, including armored plant eaters, a large fish eating embebine and various FI, including freshwater sharks.

In the rivers, semi -oak meat from a group called Fatusorus, which was made like a crocodile, was made like a crocodile, but with some differences, such as the end of the Nasser Nassor in the upper part of the head.
The last triability of the rawnschins, phytosis and some other tissues represented in the fossils disappeared in the disappearance. Frogs and turtles are still around today, while 66 million years ago, the effects of Kishodarrah have dominated the heavens, which ended the dinosaur age.
“The site has engulfed the transfer of the latest, the latest, the latest,” communications, “said Clegman.
