In the meantime, here is a picture of the ichthyosaur Grendelius mordax from the Kimmeridgian (~155.6–150.8 Ma) of Somerset. It is in Bristol Museum and Art Galleries (specimen Ce 16696). I think it’s so good, I’ll use it in my header!
Edit: I made a mistake in my naming of the ichthyosaur above. It is actually Brachypterygius mordax. It was renamed from Grendelius to Brachypterygius by McGowan in 1997 (Journal of Vertebrate Paleontology, 17 (2), 428–430).
Edit: changed to an updated photo, smoothed edges.
