Amurosaurus riabinini (Amurosaurus of Riabinin) inhabited Earth in the latest Cretaceous,
74-65 million years ago. Amurosaurus was
a bipedal herbivorous dinosaur and a member of the family Hadrosauridae. Fossil bones of adults are very rare but the available remains show that Amurosaurus was about 12 meters long.
remains were discovered by Cossacks in 1902 near the Kasatkino settlement (about
400 km away from Blagoveshchensk). The remains of a giant animal were in a
thick layer of the right side of a river. Ten years later Russian paleontologists
carried out some successful excavations in the area but in the mid-twenties their
scientific research was completely stopped. Large-scale excavations resumed
only in the mid-eighties and a unique prehistorical herbivorous Amurosaurus was found within the Blagoveshchensk
In 1991 Russian
paleontologists Yuri Bolotsky and Sergei Kurzanov first described and named this dinosaur as «Amurosaurus riabinini» (Amurosaurus of
Riabinin). The generic name is derived from the Amur River and the Greek word sauros ("lizard"). The specific name was
given in honor of the late Russian paleontologist Anatoliy Riabinin who
described first discoveries of fossil bones of dinosaurs found in that region.
Kileskus (Kileskus aristotocus)
Kileskus (meaning “lizard” in
the Khakas language) is a predatory tyrannosauroid dinosaur. It lived in Middle Jurassic on the territory of modern Krasnoyarsk region
about 165 million years ago. It appeared on Earth 100 million years earlier its
famous relative Tyrannosaurus Rex. Partial remains of its skeleton were found
in the Berezovskiy quarry not far from the Sharypovo city. In 2010 it was
described by paleontologists A.O. Averianov, S.A. Krasnolutskiy and S.V.
Mammoth (Mammuthus primigenius)
was first scientifically described by the German scientist Johann Friedrich
Blumenbach in 1799. These giants lived in Eurasia and North America in the
Quaternary period 250-10 thousand years ago, during the great glaciations. In
Russia researchers found not only skeletons of mammoths but also mummies frozen
in the permafrost. Scientists often find fossil bones of these giant animals in
Moscow and Moscow region.
amphibious Mastodonsaurus lived on Earth in the middle Triassic about 230
million years ago. These distant relatives of frogs lived in large ponds with
fresh water and were passive predators. They mostly waited for their prey hiding
near the bottom and becoming a sort of a live trap. In Russia their fossil
remains were discovered in Southern Ural. The species was described in 1955 by
paleontologist E.D. Konzhukova.
amphibians as a rule are not so large; however there are exceptions, for
example the Chinese and Japanese giant salamanders with a length of up to
almost 1.5 m. The giant goliath frog can weigh almost 3 kilos.
amphibians could reach enormous proportions, up to 9 meters in length, so our
five-meter long Paleopark inhabitant would not be the largest specimen. However
large sizes did not much help ancient amphibians to win the competition with
the first reptiles.
ancient inhabitant of our Paleopark is a lobe-finned fish Panderichthys. Its
relatives lived in the reservoirs with fresh water in the Devonian period about
370-38 million years ago. What is so special about these creatures? Panderichthys
had quite powerful fins which allowed them to cover distance from one pond to
another over land. Another peculiarity of this fish is its ability to breathe
not only under water but also atmospheric air on land. Using modern methods of
computer tomography, scientists studied fins of Panderichthys and discovered small
bones similar to the bones of terrestrial vertebrates.
was named in honor of the Russian scientist and evolutionist Christian Heinrich
von Pander. The species was discovered in 1930 by the German
paleontologist Walter Robert Gross and first officially described in 1941.
Fossil remains of such fish were found in the Baltics and the Leningrad
oblast. The first archaeological discoveries made in the Soviet Latvia in the 1970es
were studied by the Russian paleontologists. The head of excavations was the
Russian academician E.I. Vorobieva. The scientists concluded that panderichthys
wasn’t a transitional form from fish to amphibians, however learning the structure
of this unusual fish helped to understand the appearance of particular adaptations
to terrestrial life among first tetrapods.
European Cave Lion (Panthera leo spelaea)
A cave lion
is a very dangerous predator that lived in Eurasia in the Quaternary period
(170-10 thousand years ago) among other amazing animals such as wooly mammoths,
cave bears, bisons, and giant deer. Its prey was mostly large ungulates and
sometimes caves lion cubs. In Russia skulls and partial remains of cave lions
were found at different times. There are images of these animals depicted by
ancient artists. A cave lion is a close relative of modern lions.
Woolly rhinoceros (Coelodonta antiquitatis)
and bones of woolly rhinoceros are one of the most frequent paleontological
discoveries in Northern Eurasia, especially in Siberia. For a long time they
were ascribed to various mythical animals. The scientific description of this
most northern rhinoceros appeared only by the end of the 18th century. Johann
Friedrich Blumenbach called it an ancient rhinoceros. This giant herbivorous animal
lived near mammoths in the mammoth steppe 300-10 thousand years ago.
Prehistoric people knew this animal and were quite good at rhinoceros hunting.
Estemmenosuchus (Estemmenosuchus uralensis)
Fossil remains of these ancient animals were found in the Ochersky district, Perm region. The species was described by the Soviet paleontologist P.K. Chudinov in 1960. Estemmenosuchus lived on Earth in the Permian period about 260 million years ago.
