One of the newest findings from the site is large, curved teeth with prominent grooves. representing a new group of vertebrates from Owadów-Brzezinki – plesiosaurs. General morphology, stratigraphic context, and morphometric analysis indicate that these teeth belong to a representative of the Plesiosauroidea, probably from the family Cryptoclididae.
