Algorachelus peregrinus is the oldest representative of the crowngroup Pleurodira known in Laurasia. The type locality of this bothremydid isAlgora, situated in central Spain, at levels deposited during the uppermostmiddle–lowermost upperCenomanian. A new excavation was recently carried out in this town. As aresult, abundant material of Algorachelus peregrinus has been found.Several complete shells, as well as numerous partial carapaces and plastra,are presented here. The abundance of remains allows the analysis of thegeneral patterns by which some of the shells of this littoral form werepartially or totally disarticulated. The analysis of these remains not onlyshows several pathologies but also improves the knowledge about the anatomyand intraspecific variability of Algorachelus peregrinus. This newinformation allows the revision of other Cenomanian forms of Bothremydidae,both from the Middle East and from North America. Thus, Algorachelusis identified in these regions, being represented in the early or middleCenomanian of Palestine by the new combination Algorachelus parvus,and in the uppermost Cenomanian of Utah by the new combinationAlgorachelus tibert. Therefore, a relatively fast and widelydistributed geographic dispersion event is recognized, corresponding to theoldest dispersal event so far identified for a lineage of Pleurodira fromGondwana to Laurasia.
