I wrote a blog post about the giant Temnodontosaurus from Banz, Germany. The 2.3 m long skull is the first known specimen of its kind, and the original 1854 description includes life-sized illustrations of the fossil.

Fantastic news!
I've just been informed that an important study I'm involved in is set to be published next Wednesday. This photo offers a hint at what it's about. I can't reveal more details, but our study will change the way we look at these marine animals.
