Paolo997 Posted November 20, 2022 Share Posted November 20, 2022 Hi Forum, I'm asking you help to identify this speciment. Is it a big shell? or I am confusing a big portion of an ammonite? the piece is about 15cm. It was collected in the Omhden quarry (DE, next to the famous Holzmaden quarry) in the pictures you can find positive and negative plates Thanks a lot Paolo Link to comment Share on other sites More sharing options...
TqB Posted November 20, 2022 Share Posted November 20, 2022 It is a piece of the ammonite Phylloceras. P. heterophyllum is the usual one I think. @Ludwigia? Tarquin Link to comment Share on other sites More sharing options...
