I_gotta_rock Posted July 1, 2019 Share Posted July 1, 2019 I found this yesterday in Avoca, New York. It's about 3 cm long. The core looks like a cephalopod of some kind, but the exterior has me puzzled. If it were soft tissue, it wouldn't have preserved, but I have found impressions of a few others like this there and in another site over an hour away. The one field guide I have shows nothing like it and I may have to go hunt down the original 19th century sources. Any clues? 1 I refuse to give up my childish wonder at the world.

The septa are only visible on the inside of the shell. This a typical, all be it crushed shell. 2 Link to comment Share on other sites More sharing options...
