Abstract

The Ceresiosaurus genus was a Nothosauria group, that inhabited in the more meridional Alpine basins of the Tethys sea during Ladinian age (Middle Triassic). In this paper, we to describe the first finding of this genus in the Iberian peninsula, in Mont-ral- Alcover (Tarragona), an outcrop with abundant fauna and flora but where dolomitization destroyed all original skeletal material. We rewieve the taxonomic position of the genus Lariosaurus and Ceresiosaurus to belong to Lariosauridae branch by means of cladistic analysis and we discuss some paleobiological and paleoecological aspects.
