Taxonomy

Iserosaurus was originally described as a new taxon of mosasauroid by Fritsch (1905) on the basis of a disarticulated skeleton from Turonian-age chalk deposits in Bohemia, Czech Republic.^[1][2] However, Persson (1963) tentatively listed it as a dubious plesiosaur in his overview of plesiosaur classification.^[3] Karl (2002) recognized Iserosaurus as being a protostegid turtle and assigned it to cf. Archelon.^[4] Kear et al. (2013) agreed with Karl (2002) that Iserosaurus is a marine turtle but noted differences from Archelon, so assigned the genus to Protostegidae indet.^[5]
