Leptocleidus

Lower Cretaceous plesiosaurs are rare, so Leptocleidus is important because it fills a gap in the fossil record of plesiosaurians. Leptocleidus was once considered to be a late surviving member of the family Rhomaleosauridae but it has recently been reidentified as a close relative of polycotylids.

Gronausaurus

‘Gronausaurus‘ was named in 2013 (Hampe, 2013). It is now regarded as a junior synonym of Brancasaurus (Sachs et al. 2016).
