Short summary
The Spanish Algorachelus peregrinus is the oldest pleurodiran turtle known in the Northern Hemisphere. New material is presented, including several shells. The patterns by which some of them were disarticulated are analyzed. Several pathologies are identified. The knowledge about the anatomy and intraspecific variability is improved. Algorachelus is recognized in the Middle East and North America. The oldest known dispersal event of Pleurodira from Gondwana to Laurasia is characterized.
