New highly pachyostotic nothosauroid interpreted as a filter-feeding Triassic marine reptile

Abstract

Two well-preserved specimens of a new eosauropterygian from the Upper Triassic of Central Spain are attributed to a new taxon, Paludidraco multidentatus gen. et sp. nov. It is a member of Simosauridae that presents several exclusive characters suggesting a highly specialized trophic adaptation. This discovery increases the already high ecological disparity of the Triassic marine reptiles.
