I just read that a very interesting fossil of a belemnite was discovered at the Plattenkalk of Nusplingen, and it had a preserved beak. The two parts of the beak are disarticulated and very tiny. You can see a photo of the fossil at this site: http://www.spiegel.de/wissenschaft/natur/0,1518,551726,00.html
(You have to click on the small photo which where "rostrum" stands over a part of a belemnite)

Thanks for that link Sordes, some very nice pics of the Belemnite. Correct me if i'm wrong, Kammerapparat = Camera apparatus or Phragmocone- Armkrone = Arm crown? or arm hooks, and Kiefer = beak (upper and lower on the other photo). And maybe even some of it's last meal preserved under the phragmocone. :smile:

Here´s a comparable free translation:

The find from Nusplingen: Belemnite with the jaws and small hooks of the tentacles (sounds better than arm crown I think). At the left are relics of the phragmocone (btw Kammer means chamber) and the torn up ink sac. The rostrum was bitten off and is missing.
