the Dinosaurs appeared in the world in the triassic period, and there from far away are also in this case the first research results. Starring are dinosaurs in addition to crocodiles, both arkosaurusten heir.
Arkosaurukset were triaskauden at the beginning of risen quickly in the animal kingdom ranked first, after the end-permian end mass extinction event had decimated the previous rulers.
Triaskauden the end of the 210 million years ago, dinosaurs were not yet the animal kingdom undisputed master. Evolution in a different direction that left relatives of the great gulf were a threat to them, told the Journal of African Earth Sciences (switch to another service) -the journal published a fossil study.
the south african black rand university (you move to another service) according to the study, at least two of the Rauisuchia-genus of the crocodile species preying on plant-eating dinosaurs.
Widespread family off triaskauden the end of
the Study provided evidence to South African research institutions for the collection of fossils. Rauisuchia-fossils have been found widely elsewhere, all the world nykymantereilta the whole of antarctica with the exception of.
the Family members were very different sizes and shapes. The largest were up to ten meters. The curved teeth were serrated.
Such features, despite the family story, the end was no longer tens of millions of years. Rauisuchiat die trias and jurakauden the fold-paleogene extinction event, which survived the dinosaurs opened the way up the food chain.
the Crocodile in turn, continue the development of the second arkosauruslinjasta. The earth’s current inhabitants, only crocodile animals are arkosaurusten heir – and of course the birds, which in due course evolved from dinosaurs.

Rhoetosaurus browne – the Giant was varvasastuja
the One Australia found jurakauden sauropodi, long-necked plant-eating giants, walking on tiptoe, although the largest specimens were up to 40 tons in weight, says queensland university (you move to another service) survey last spring.
the Heel is not taken to the ground, even if it is on the other hand, had the air either, the researchers explained. They had come to fossil made 3D model on the basis of the conclusion, that the plaintiff below steps to soften the process was a meaty pillow.
Without this key factor to sauropod from might never have become so huge, estimated in the Journal of Morphology (you move to another service) in the journal published by the research the article main author of Andréas Jannel .
around the world to find the footprints on the basis of the corresponding structure was sauropodeilla general.
Hokkaido found Kamuysaurus japonicus -a dinosaur skeleton is almost complete.Hokkaido yliopistoKamuysaurus japonicus “dragon god” loved the sea
This month in Scientific Reports (you move to another service) -journal publication of research presented kaikkian largest-ever Japan to find the dinosaur, 73 million years ago, the hadron – namely, the duck-billed dinosaurs.
This plant eater weighed at least four tons or even more, if it turns out that it walked on four legs, Hokkaido university (you move to another service) research reports. Large size means that the animal was named “”the japanese dragon god”.
Even if the new dinosaur species is named in the world today top ten every year, for Japan this is just the all-time eight the name of the new species.
the Species shows that in Japan or East Asia’s other independent evolution, said study lead assistant professor Yoshitsugu Kobayashi .
the discovery of the place special is also the location of an ancient sea beach. Maybe some dinosaur species were enjoying exceptionally just by the sea, which may have been a significant factor in species diversification, the researchers say.
I Saw lizzy Cryodrakon boreas, distant time in the “dragon”, thinks the artist. Davos Maas / the London Queen Mary’s yliopistoCryodrakon boreas – “Icy dragon” was the aircraft wingspan
the pterodactyl were not dinosaurs, but this their contemporaries deserve to be presented among those huimien properties. It was one of the world’s all-time greatest flight ability of the fathers of the animals.
the Wing ten meters of wingspan equivalent to many of today’s fighter planes, for example, the Finnish air force used hawk drives.
250 pounds of weight of carnivore was a threat even dinosaurs for the chicks. And when the creature landed on the ground, the head was the same height as the nykykirahveilla.
Fossilized bone were found already a quarter of a century ago, but it was thought for a long time belonged to the already known pterosaurus – namely, the pterodactyl species, says the research article of the lead author, paleontologist David Hone london Queen Mary university.

as a Separate species as a great beast was presented in the Journal of Vertebrate Paleontology (switch to another service) in the journal this month. The name means “northern icy dragon”, though the canadian site had 76 million years ago, much warmer.
vesper-a-saurus paranaense – the Desert of the little beast left both prints
the 1970s found the strange footprints they finally got their explanation, when they left the dinosaur species remains found in the state of paraná in Southern Brazil.
in Summer, Nature Scientific Reports (you move to another service) in the journal the published study was presented to the creature, which jumps to 90 million years ago, across the desert on two feet but one toe in.
Toes was the foot in three, but the little beast can afford them only in the middle, told Cruzeiro do Oeste paleontologist of the museum’s scientists.
the Creature makes it special is also the fact that Paranásta not previously been found in the country move out of dinosaurs, only their contemporaries, in the sky curve down to pterosauruksia.
the Species had a height of only 75 centimeters and weight of 15 pounds.
This artist has come to the conclusion Suskityrannus hazel’s. A few tens of kilograms of weight of the creature family was all about dinosaurs the famous, T. rex.Andrey Atuchin / Virginia Tech Suskityrannus hazel – Miniotus proved tyrannosaur
20 to 40 pounds – enough weight was 92 million years ago lived creature, which now complement tyrannosaurusten family tree.
despite its Small size it was relentless and fast predator with a strong bite, the researchers concluded the fossils on the basis of.
U.s. state of New Mexico found a long time ago two partial immature individuals in the skeleton. Went ten years, before the species was found in nine-ton T. rex previously unknown mini cousin.
the Species, which scientists have given the nickname “the cretaceous coyote”, presented at the spring Nature-Ecology & Evolution (you move to another service) in the journal.
Suskityrannus hazel skeleton compared to the large relatives in the T. rex’s jaw bone. Virginia Tech
Suskityrannus hazel so tyrannosaurusten evolutionary explosion with the advent of the, said in a research article, the lead author, geosciences assistant professor Sterling Nesbitt usa, Virginia Tech university (go to another service).
the Change was rapid. Only ten million years later tyrannosaurukset were our planet’s overstuffed valtijoen, and the power lasted until, when the Earth struck by an asteroid made the dinosaurs end 66 million years ago.
Nesbitt has a very special role in a new species in the story: he participated in the 16-year-old schoolboy paleontologist on the dig, and there he found Suskityrannus hazel the first character, the mud törröttäneen tibia song.
