New Members Fossillife300 Posted July 23 New Members Share Posted July 23 I have a number like this and have always called them actinoceras. Wide bumpy siphuncle, striations, hole or limestone inside the siphuncle. If someone has a confirmation on this ID, that would be much appreciated! Also would it be bigsby? Thanks! Gull River fm.

FossilDAWG Posted July 23 Share Posted July 23 I would definitely agree with Actinoceras. I struggle with the species level ID, for the reason I discussed in your other thread about Loganoceras. Don 1 Link to comment Share on other sites More sharing options...
New Members Fossillife300 Posted July 25 Author New Members Share Posted July 25 Amazing thanks! Understood. We'll probably stick to the genus level. We're determined to understand our cephalopods as best we can! Link to comment Share on other sites More sharing options...
