一种大型海鳄化石被发现

只看楼主收藏回复

学名是暴泳鳄(Tyrannoneustes lythrodectikos)
lythrodectikos一词不知是啥意思
下颌长达97厘米,颅长92厘米,全长约5米,侏罗纪中期

    又有一种海鳄被发现
    Maledictosuchus riclaensis ,侏罗纪中期,被发现於西班牙
    此外在英国也发现了地龙亚科Torvoneustes的残骸。
    现在还是壬辰年,壬为海水,辰为龙,今年发现的鳄类化石可真多,尤其是海鳄类。
    Re-description of a long-known, but little studied, metriorhynchid crocodylomorph from the Oxfordian of England begins to help fill the ‘Corallian Gap’. This ‘Gap’ represents a paucity of vertebrate remains from the Oxfordian of England. Filling the ‘Corallian Gap’ has important implications for our understanding of metriorhynchids from England, especially as there was a shift in this ecosystem from being metriorhynchine dominated in the older Oxford Clay Formation, to a geosaurine-dominated fauna in the younger Kimmeridge Clay Formation. The re-description of the specimen reveals that it is a member of the derived subclade Geosaurini, which most likely pertains to the genus Torvoneustes.
