 As in the Triassic, there was apparently no land over either pole, and no extensive ice caps existed.The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of that future landmass was submerged under shallow tropical seas; famous locales include the Jurassic Coast World Heritage Site in southern England and the renowned late Jurassic "lagerstätten" of Holzmaden and Solnhofen in Germany.In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface.
