Diagnosis
ReferenceDiagnosis
V. Fischer et al. 2013Leninia stellans is characterized by the following potential autapomorphies within Ophthalmosauridae: posterior process of the maxilla extending as far as the middle orbit (reminiscent of Ichthyosaurus intermedius; Maisch, 1997); presence of an anterior process on the prefrontal covering the nasal; frontal–parietal suture formed by the means of elongate medial forked processes of the frontal and the parietal; presence of an anterolateral process of the supratemporal contacting the parietal. Leninia stellans is also characterized by a combination of features shared
