Fig. 3. Comparative illustration of key anatomical areas of the skull in several Lower Jurassic plesiosauroids. A. Plesiosaurus (redrawn from Storrs 1997). B. Seeleyosaurus (redrawn from Grossmann 2007). C. Occitanosaurus (based on Bardet et al. 1999). D. Hydrorion (based on Maisch and Rücklin 2000; Grossmann 2006). E. Microcleidus (based on BMNH 36184, AS personal observation). F. Lusonectes sauvagei gen. et sp. nov. An alternative interpretation of Occitanosaurus suggests that the pterygoids met on the midline behind the posterior interpterygoid vacuity (Mark Evans, personal communication 2010).
