What scientists have found over the summer - Rossiyskaya Gazeta

Ural paleontologists carried out a lot of research during the field season. In particular, they managed to explore the caves of the Big Urals, the Crimean cave “Tavrida” and the banks of the Siberian rivers.

In Crimea, scientists worked side by side with colleagues from all over the country. In Yekaterinburg, they brought the jaw of a giant hyena, pachycrocuta, about this find “RG” reported earlier.

Associate Professor of the Department of Theory and History of International Relations of the UrFU Anton Kochnev noted that the bones are 1.5-1.8 million years old. The jaw is remarkable in that it is well preserved. The animal’s dental apparatus was created in order to crush the bones of large animals. Traces of abrasion are clearly visible on the teeth, which means that in this cave, which was dubbed a paleontological pearl, the hyena, like many other predators, lived and ate very well. Moreover, according to preliminary estimates, pahikrokuta died a natural death.

Another curious find from Tavrida is the jaw of an Etruscan bear, a contemporary of a hyena. It is interesting to explore in that it is the ancestor of all brown and cave bears. About two million years ago, two lines of predators with different eating habits departed from it. Cavemen are pure vegetarians and brown ones are unpretentious and omnivorous.

According to Dmitry Gimranov, Senior Researcher at the Laboratory of Natural Science Methods in Humanitarian Research, UrFU, in the caves of the South Urals and Bashkiria, it was possible to find mainly the bones of cave bears. But there were also the remains of porcupines, rodents, bats.

This season has been a good one for collecting mammoth bones. The fact is that in recent years there has been a lot of water on the rivers of Western Siberia. This summer it was not enough, and, eight years later, paleontologists continued to work on the Irtysh and Tobol. According to Pavel Kosintsev, a senior researcher at the Institute of Plant and Animal Ecology of the Ural Branch of the Russian Academy of Sciences, a leading researcher at the Laboratory of Natural Science Methods in Humanitarian Research at the Ural Federal University, the river beaches finally became exposed and released the bones that had accumulated there for millennia – the oldest finds are 300-400 years old. Scientists have collected large collections of mammoth remains and the ancestors of mammoth fauna.

– The fees are interesting because we get a complete picture of the life of ancient animals. The creatures died, their remains were buried together – mammoths, wolves, rhinos, polar foxes. Nowadays, the river erodes the complex and exposes bones. Studying them, we can carry out complete reconstructions, and, among the remains, animals of different ages. The composition of the fans and the relationship of animals, the way they influenced each other. We determine the age structure of mammoths, we find out how many cubs there were, how many adults, the scientist said.
