Fossile Reptil-Eischalen (Chelonia,Crocodilia, Dinosauria) aus dem unteren Barremium von Galve (Provinz Teruel,SE-Spanien)

The Lower Cretaceous vertebrate bearing sediments of Galve (province of Teruel, SE Spain) have yielded some hundred fossil eggshell fragments, all slightly diagenetically altered. Concerning their microstructure, an assignment of the material to different taxa of reptiles was possible. The eggshell assemblage of Galve consists of a-c) three types of chelonian eggshells, one of them probably representing the subfamily Batagurinae, which would extend this taxon back into the Lower Cretaceous, d) the oldest known crocodilian eggshells, with lacunae systems on the outer surface, comparable to Recent taxa, and e-f) two different types of dinosaurian eggshells. In correspondence to the suggested fluviatile paleoenvironment of Galve, the fossil eggshells described herein are fragmented and represent mostly turtles and crocodiles.
