In Siberia found begabter.
Russian scientists have discovered a new species of ancient mammals, belonging to the group of so-called megalogistic (Multituberculata) and resembles a modern rodents.
Specialists from St. Petersburg state University and Tomsk state University found the remains of mammals during a joint expedition in Siberia.
“We found a very primitive representative of this group: he had to live in the Jurassic period (145 million years ago), the traces left in sediments belonging to the early Cretaceous (100-125 mA)”, — quotes Agency Sputnik Professor of Saint-Petersburg state University Pavel Sucasa.
It is assumed that the mammal was an ancient ancestor of modern rodents. Rodent resembled externally a mixture of hamster and rats. A creature that probably is also one of the progenitors of all herbivorous mammals, called bhagabatam (Baidabatyr clivosu).
“Discovery has confirmed that for 40 million years in Western Siberia there was a huge evolutionary stasis, when species composition of mammals and amphibians was not changed”, — concluded the expert.
For protection from predators at Baidabatyr clivosus had poisonous spurs on the feet, similar to those available to the platypus or echidna. According to researchers, poisonous spurs could be a peculiar feature of all mammals of the period.
The site was near the village of Bolshoi Kemchug in the Krasnoyarsk region. The anatomical features of the premolar allowed to take begabter to a new kind megalogistic (Multituberculata) — extinct mammals that arose and disappeared in the Mesozoic era.
