VStergios Posted February 2, 2019 Share Posted February 2, 2019 Need help identifying the following fragment. Took it out of the limestone in the locality Theokafta of the Argolis Peninsula, near the Ancient Theatre of Epidaurus (Greece, eastern Peloponnesus). The limestone contains condensed ammonoid beds of the Hallstatt facies (Triassic: Anisian–Ladinian). Since I've never seen an ammonite with a cigar shaped ending and the belemnite fossils I've see so far are bullet shaped, I would really appreciate your opinion on the matter! The size is 5cm and diameter 1,5 to 2cm. 1 Link to comment Share on other sites More sharing options...
TqB Posted February 2, 2019 Share Posted February 2, 2019 Hard to identify based on that bit but it's not ammonoid with a chamber wall of that simple shape. Both orthocerid nautiloid and aulacocerid belemnoid (see Atractites for example) are possible from the Middle Triassic. (It's a piece of phragmocone.) 4 Tarquin Link to comment Share on other sites More sharing options...

That's great to hear, I read that phragmocones aren't easily preserved! I 'll look into it - thanks for the speedy reply! 1 Link to comment Share on other sites More sharing options...

Ludwigia Posted February 2, 2019 Share Posted February 2, 2019 @VStergios It looks like a fragment of an orthocone nautiloid to me. Try Michelinoceras or Aulacoceras. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
