Poland, once tropical, unearthed 150 million-year-old sea monster fossils

Researchers have discovered a 150 million-year-old sea monster fossil called The Ondolong in a cornfield near a village in southern Poland, foreign media CNET reported. In a paper published in the journal Proceedings of the Geosciences, researchers at the Polish Academy of Sciences described the Jurassic-era giant animal.


The jaw son of the upper dragon is about 8 feet (2.4 meters), which is 4.5 times larger than the tyrannosaur. The dragon is almost twice the size of a modern killer whale, weighs tens of tons and can devour any creature in the water. The fossil is about 33 feet (10 meters) long and surrounds ancient crocodile teeth and turtle shells. The fossil was discovered in a former tropical archipelago dotted with heated lagoons and reservoirs.


“This new place is rich in fossils of coastal and deep-sea reptiles,” the researchers wrote, located in the northeast of the Holy Cross Mountains, near the village of Kercianovetze.
