FossilDAWG Posted May 15, 2020 Share Posted May 15, 2020 It's doing a good impression of a cephalopod, but the irregularity of the "chambers" makes we favor the banded chert ID as well. Don Link to comment Share on other sites More sharing options...
westcoast Posted May 16, 2020 Share Posted May 16, 2020 If chert, it would be a highly eroded water worn clast later incorporated into a different sediment, ie a part of a matrix supported conglomerate. Could be. Do a scratch test with steel nail or put a drop of acid on and see if it fizzes. Link to comment Share on other sites More sharing options...
