From: The rise of macropredatory pliosaurids near the Early-Middle Jurassic transition
Dental morphospace occupation of Lorrainosaurus keileni. (a) Plot of principle coordinates analysis (PCoA) results with the PCo1/PCo2 axes showing L. keileni (bold type) versus rhomaleosaurid (grey shading) and Jurassic (blue shading) to Cretaceous (green shading) thalassophonean pliosaurids. (b) Cluster dendrogram of conical (circles), sub-trihedral (semicircles) and trihedral (triangles) thalassophonean tooth crown morphologies from the Middle (dark blue) and Late Jurassic (light blue) to Early (dark green) and Late Cretaceous (light green).
