Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Motani 1999 | Edentulous. | |
| M. W. Maisch and A. T. Matzke 2000 | "Large ichthyosaur, exceeding 3m in length, skull with very large
orbit and short postorbital skull segment, dentition reduced in adults, forefin with elements forming closely fitting mosaic pattern, more than one well developed preaxial finger the posteriormost of which contacts humerus in additional facet, up to 8 fingers in total, ulna much smaller than radius." | |
| C. Ji et al. 2016 | No contact between supratemporal and postor-
bital; basioccipital extracondylar area reduced; teeth reduced and probably absent; postorbital region broad; humerus with three distal facets, the anterior one articulating with a preaxial accessory element; facet for ulna smaller than radial facet and set off obliquely; phalanges polygonal and closely packed; elements in longest digit probably >24; hind fin preaxial and postaxial accessory digits present. |
