Paleontologists within the village of Krzyżanowice have just lately found bones from pliosaurs, an enormous Jurassic sea predator in a cornfield close to Iłża (Mazowieckie). The pliosaurs have been the biggest marine predators dwelling in Jura 150 million years in the past.
Paleontologist Dr. Daniel Tyborowski from the Museum of the Earth of the Polish Academy of Sciences in Warsaw said, “They measured over 10 meters in length and could weigh up to several dozen tons. They had powerful, large skulls and massive jaws with large, sharp teeth. Their limbs were in the form of fins. We found bones of these pliosaurs in the north of the Świętokrzyskie Mountains.”
“Discoveries in the form of the remains of Jurassic pliosaurs are very rare. In Europe, they have been discovered only in a few countries, never before in Poland.”
The fossilized stays of a shocking assemblage of creatures from the Late Jurassic interval, together with the cranium and tooth fragments from a big pliosaur. Together with pliosaur bones, paleontologists additionally found the stays of a number of different animal species, together with plesiosaurs (long-necked cousins of pliosaurs), turtles, and ancestors of modern-day crocodiles. In complete, a number of hundred bone stays have been counted.
Tyborowski famous, “Sea turtles ate large snails, while they fell prey to large crocodiles. We know this because we found teeth marks left by those reptiles on turtle shells. On the other hand, powerful pliosaurs hunted all animals whose fossils we discovered at this site.”
“The research on the newly discovered cluster of fossilized remains of Jurassic animals in Krzyżanowice is just the beginning. We hope that the next months and years will bring even richer material in the form of bones of large reptiles.”
A study is revealed within the Proceedings of the Geologists’ Affiliation.
