Sorry, no etymologies found.
Oh, I also made it through two articles in the new Journal of Vertebrate Paleontology yesterday, "Generic reassignment of an ichthyosaur from the Queen Elizabeth Islands, Northwest Territories, Canada" and "A remarkable case of a shark-bitten elasmosaurid plesiosaur."
Conventionally imagined as a dainty-headed predator of small prey, and an early elasmosaurid, new specimens show that it was quite robust-skulled with features suggesting that its head was well suited for handling fairly large prey (M. Evans, data presented at SVPCA).
Two newly discovered elasmosaurid plesiosaur specimens from the Cretaceous contained a surprise that told us a little more about their diet.
Rather than being an elasmosaurid, it may in fact be a close relative of the cryptoclidids (O’Keefe 2001).
