What's worse than having a Xenacanthus slap your face after catching and releasing it in your birthday?
Having your daughter and close friend remind you of it with a picture, of course!

Day 8 of #sharkweeksketchjam - XENACANTHUS 🦴🦈

I saw a model of this prehistoric shark in a museum a few months ago and wanted to draw it- finally got around to it recently.

I have this one. Love it. :) It confidently tells us that Stegosaurus flattened its plates down as a defense mechanism, and that it probably then curled up like a hedgehog. Glorious aquatic Brachiosaurus too! Check out Xenacanthus in the back, though. I adore that painting.

Despite Barbclabornia teeth being tiny compared to those of Xenacanthus or Orthacanthus, this Permian aged genus of chondrichthyan is the largest of the xenacanthids. This species lived alongside Orthacanthus compressus and Orthacanthus platypternus.

A group of tiny Permian chondrichthyan teeth of Barbclabornia luedersensis from the Wellington Formation in Waurika, Jefferson County, Oklahoma, USA. The lack of a central cusp distinguishes this species from the contemporary xenacanthid, Orthacanthus.
