Data for: New marine reptile fossils from the Late Jurassic of Poland with implications for vertebrate faunas palaeobiogeography

Vertebrate remains, mostly cryptodiran turtle shell fragments, pliosaur skull bones and teeth, plesiosaur vertebrae and crocodylomorph isolated teeth are described from the Upper Jurassic (Kimmeridgian) limestone beds of Krzyżanowice in the NE border of Holy Cross Mountains in Poland. The analyzed vertebrate fossils were collected during the palaeontological excavations in 2018 by authors and also in 1960s by the team from the Museum of The Earth of the Polish Academy of Sciences. All osteological remains are generally very well preserved. This interesting vertebrate bones association from the upper part of the Kimmeridgian represents fossils of animals from two different types of environments. The first contains costal reptiles like turtles and crocodylomorphs. The second one contains large pelagic animals – pliosaurids and plesiosaurids. This new vertebrate fauna from Poland has been correlated with age-equivalents from other regions of Europe and both boreal/subboreal and mediterranean palaeobiogeographical realms.本文记述了波兰圣十字山脉东北边境克罗扎诺维采（Krzyżanowice）上侏罗统基默里奇阶（Kimmeridgian）灰岩床中产出的脊椎动物化石残骸，其中以隐颈龟类（cryptodiran）龟甲碎片、上龙类头骨骨骼与牙齿、蛇颈龙类脊椎以及鳄形超目孤立牙齿为主。本次分析的脊椎动物化石分别由本文作者于2018年的古生物发掘工作中采集，以及由波兰科学院地球博物馆团队于20世纪60年代采集。所有骨学标本均保存状况极佳。这套产自基默里奇阶上部的有趣脊椎动物骨骼组合，代表了两类不同栖息环境下动物的化石：第一类为近岸栖息爬行动物，如龟类与鳄形超目动物；第二类则为大型远洋动物——上龙科与蛇颈龙科动物。这套产自波兰的全新脊椎动物群，已与欧洲其他地区同期地层的化石组合开展生物地层对比，并可归入北方/亚北方及地中海古生物地理域。
