A small place in the Polish province, east from Opole (Opole-Silesia): On the area of an enormous open mining pit of clay - where the red Keuper is diminished for the processing from cement one found for approx. 8 years first fossil traces of a prehistorican fauna and flora.


The 225 million years old fossils are remnants of carnivores such as Metoposaurus, Capitosaurus, Phytosaurus, Rauisuchus and their vegetarian relative Aetosaurus. A recently discovered kind of the primary and perhaps also the oldest form of the dinosaurs from the time before 225 millions years was founded in Krasiejów.


Since then officially this nature of dinosaurus is called Silesaurus opolensis.

This species prepared the appearance of the dinosaurs, whose oldest representatives were discovered by Jerzy Dzik in the form of individual bones and partially nearly complete skeletons in the last 2-3 years in the Polish Krasiejów. Dzik is a professor in palaeobiology at Palaeobiology Institut of the Polish Academy of Sciences in Warsaw. He led among other things the research in the desert Gobi.

The location in Krasiejów is in opinion of the professor the first mass cemetery with so complex accumulation of well preserved large vertebrate animal.


Except enormous amounts of individual bones there was also nearly complete heads and large parts of well preserved skeletons discovered, which were thoroughly examined in specialized laboratories in Warsaw.


"it is a world sensation, because in the today's time very rarely new palaeontologic locations are discovered, where the fossil material are so rich”, so says Jerzy Dzik.


The investigations of the area are not final yet, and one makes daily new finds. This area was for approx. 230 millions of years in the probably former river delta within the bank range of the flat Germanic Basin, which extended until France and to the North Sea.
