Steph67 Posted Tuesday at 11:41 AM Share Posted Tuesday at 11:41 AM Hi, Any help identifying these please? 1st one : Top view : 2nd one (crinoïd? with stem?) : 3rd one (almost certain these are bones - Nothosaurus?) : 2 Link to post Share on other sites
Tidgy's Dad Posted Tuesday at 06:22 PM Share Posted Tuesday at 06:22 PM To me, the first one looks like an orthocerid nautiloid with parts of some septa showing and the lumpy bit in the middle being the infilled siphuncle. Link to post Share on other sites
rocket Posted Tuesday at 06:35 PM Share Posted Tuesday at 06:35 PM Nautiloid, yep, but I think it is not an orthocone, in Muschelkalk we sometimes find huge nautiloides like "Germanonautilus" I would assume this belongs to this genus 1 Link to post Share on other sites
Steph67 Posted Tuesday at 06:42 PM Author Share Posted Tuesday at 06:42 PM Mmmh, yes the shape is very similar, excepted the segments accross, perendicular. and I have searched the period of a orthocerida nautiloid and it seems it is very earlyer (-490 M), here we are between 200 and 250 M).

But this part could be what part of it? I can't see the localisation on the animal... Link to post Share on other sites
Steph67 Posted Tuesday at 06:46 PM Author Share Posted Tuesday at 06:46 PM Here is the Germanonautilus I suppose? Link to post Share on other sites

No, this is incorrect. The Orthocerida survived into the Triassic with a few genera such as Michelinoceras. 1 Link to post Share on other sites
