Scale-like (or fibrous) structures are also documented on the leading edge of some ichthyosaur fins — not commented on much in literature but potentially an interesting avenue for future research

Scales being found only on the flippers here immediately brings to mind cetaceans that roughen and thicken the leading edge of their fins & flippers for hydrodynamic purposes.

Hello new Bluesky followers- enjoy some Mosasaurus reconstructions.
I tried to incorporate the clavicles and interclavicles into these reconstructions, as well as a shallower chest due to lizardy swept-back ribs.

Guanlingsaurus, my skeletal restoration of this giant ichthyosaur. A short, toothless snout, high vertebral count, and reduced ossification acrodd the skeleton make this a very unique animal

Man I haven’t posted on here in a while- here’s a currently unfinished painting of the supremely weird Sclerocormus

I did skeletal and some other illustration work for a new publication by Dr. Andrzej Wolniewicz et al., publishing a new of saurosphargid and a new scheme for sauropterygian evolution. Give it a read! https://elifesciences.org/articles/83163

It also has flippers. Dinocephalosaurids are close to Tanystropheids, but Dinocephalosaurus’ aquatic habits (far more specialized than Tany) and extreme neck were evolved convergently. Fascinating animal to be sure

I rarely draw dinosaurs, but here’s a Corythosaurus

A reconstruction I did of the Halisaurines Eonatator (the little guy on the bottom), known from a nearly complete skeleton, and Pluridens serpentis, a titanic relative known just from the skull. Such odd proportions!
