connorp Posted April 21, 2020 Share Posted April 21, 2020 Part of an ammonite whorl. Not sure if a species can be determined, it’s pretty worn. Do you know what age it is? 4 Link to comment Share on other sites More sharing options...

Do you know what age it is? +1 for part of ammonite whorl. They are called "Katzenpfötchen" (Cat Paws) in German... 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted April 21, 2020 Share Posted April 21, 2020 It's part of the phragmocone, since the impressions of the septal walls are visible on it. 3 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Maygar Posted April 22, 2020 Author Share Posted April 22, 2020 Thank you. On the second to last picture that shows the 3 protrusions/nodules -- what might those be? Interesting... Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted April 22, 2020 Share Posted April 22, 2020 The protrusions are exactly that. Protrusions within the living chamber that probably followed the body contours of the organism. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

Interesting... You have to think 3-dimensionally. The protrusions are parts of the septal wall where they anchored to the shell, which in your case has dissolved away completely. What you have there is a so-called steinkern, or internal cast of part of the original creature, formed by the hardened sediment which filled it after death, . 1 Greetings from the Lake of Constance.
