dolevfab Posted December 28, 2017 Share Posted December 28, 2017 I have found a straight shelled Cephalopod in the ordovician of Russia. Middle ordovician asery level of the Leningrad area. Its different from the usual cephalopods found there. The septa are closely spaced and the siphuncle is small and close to one side of the couch. (Not the centre) From what I can tell it's neither orthoceras nor endoceras. The shell has ribbing on the bodychamber it which is also atypical. I would really appreciate any further insight!!

TqB Posted December 28, 2017 Share Posted December 28, 2017 Maybe an oncocerid of some sort. There are straight or nearly straight ones and they can be annulated (according to the Treatise on Invertebrate Paleontology). 1 Tarquin Link to comment Share on other sites More sharing options...
