These are fossils of pliosaur, a huge marine predator that lived during the upper Jurassic and could measure more than 10 meters.
A team of paleontologists has found some pliosaur bones , a huge short-necked marine predator that lived during the upper Jurassic about 150 million years ago , in a cornfield near the Polish town of Krzyzanowice, north of the Swietokrzyskie mountain range, Science in Poland reports .
“They were over 10 meters long and could weigh up to several dozen tons. They had large and powerful skulls and huge jaws with large, sharp teeth. Their limbs were shaped like fins,” explained one of the discoverers, Daniel Tyborowski, of the Museum. from the Land of the Polish Academy of Sciences. “In Europe, they were discovered only in a few countries, never before in Poland,” the scientist added.
In addition to the pliosaur fossils, paleontologists also found several other species of animals from the same era . These include plesiosaurs (which unlike the pliosaurs had a long neck), turtles and ancestors of modern crocodiles measuring about six meters.
During the age of the dinosaurs, the area of the Swietokrzyskie mountain range was an archipelago of tropical islands with warm lagoons and shallow swamps where different prehistoric species lived. “The powerful pliosaurs hunted all the animals whose fossils we discovered on this site,” Tyborowski said.
“We hope that the coming months and years will bring even richer materials in the form of bones of large reptiles,” he concluded.
