Acrocoelites gracilis


belemniten

A beautiful and well preserved belemnite (Acrocoelites gracilis) from Dormettingen. Dormettingen is a city "near" Holzmaden, where you can also find fossils from the lower Jurassic. The belemnite is about 17 cm long ! It seems to have a small pathology on the tip.

Hi Sebastian, a beautiful belemnite! - I don't believe it's Youngibelus though (now called Cuspiteuthis again by the way).

At that length, much of the rostrum would be epirostrum, with a distinctive widening 7cm or so from the right hand end where the short normal rostrum underlies it.

This seems to be all or mostly normal rostrum and, if that's the case, I think it would be Acrocoelites gracilis. (The pathology could instead be a short epirostrum which is often present in some species of Acrocoelites.)

(I bought an Ohmden one just like it!)

Thanks Tarquin ! Very informative :fistbump: I will correct it as soon as possible.
