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里扎诺维采（Krzyżanowice）地区上侏罗统基默里奇阶（Kimmeridgian）灰岩地层中产出的脊椎动物化石，其主要类群包括隐颈龟类（cryptodiran）壳碎片、上龙（pliosaur）头骨骨骼与牙齿、蛇颈龙（plesiosaur）脊椎以及鳄形类（crocodylomorph）孤立牙齿。本次分析的脊椎动物化石，一部分由本文作者于2018年的古生物发掘工作中采集，另一部分则于1960年代由波兰科学院地球博物馆（Museum of The Earth of the Polish Academy of Sciences）团队发掘获得。所有骨学遗骸均保存状态极佳。这套产自基默里奇阶上部的脊椎动物骨骼组合，涵盖了两种截然不同沉积环境下的动物化石：其一为沿岸爬行动物，包含龟类与鳄形类；其二为大型远洋动物——上龙科（pliosaurids）与蛇颈龙科（plesiosaurids）。此次在波兰发现的全新脊椎动物群，已与欧洲其他地区的同期地层化石，以及隶属于北方/亚北方（boreal/subboreal）与地中海（mediterranean）古生物地理区系（palaeobiogeographical realms）的同期化石完成了生物地层对比。
