Paleontologists from and
Germany described the teeth of a giant long-necked dinosaurs from the group of Sauropods,
living in high geographical latitudes. The remains were discovered in the South-West of Yakutia, on pleaserate 62 degrees, which makes
the discovery of the northernmost traces of sauropods in the world, write the authors in
the journal lethaia is.
Dinosaurs is extensive
a group of reptiles appeared in the Triassic period about 240 million years ago.
After the Triassic-Jurassic extinction 201 million years ago, they became dominant
terrestrial vertebrates and continued to occupy this position until the Cretaceous-Paleogene
the extinction 65 million years ago. The event survived only a small part
dinosaurs that were the ancestors of modern birds.
Since the habitat
dinosaurs position of the continents was different from today. Because of this climate
was different not only locally, as with the lithospheric plates moved and
the coordinates of the points on the surface, but also globally. However, not much is known finds
naticia dinosaurs (not related to the ancestors of birds) to those for high, then
there are areas that were during the life of the respective types relative to
close to the pole.
Generally of naticia
dinosaurs closer to the pole, scientists find the remains of the representatives of ornithopoda,
stegosaurs, the ankylosaurs, ceratopsids, pachycephalosaurs, and a variety of
predatory dinosaur (a theropod). Least likely in the polar regions meet
the sauropods — four-legged herbivorous dinosaurs, which, in particular,
include the largest ever land animals.
Russia and Germany with the participation of Alexander Averyanov (Alexander O. Averianov) of the Zoological Institute
Ran described the find in the Yakut location Teeta isolated teeth of adults and young sauropods from the group macronaria. Pleaserate places
estimated at 62 degrees, which makes finding the most Northern for this group
