OutdoorAK Posted May 5, 2020 Share Posted May 5, 2020 Hi everyone! First time posting here. I went out over the weekend to do something outdoors during the quarantine (easy to do in Alaska) and went to a spot known for marine fossils (especially sea lilies) on the Little Nelchina River here in Alaska. I was picking up fossils on an eroded cliff side above the river when I noticed this laying on top. My question is, is it a bivalve or tooth? I don't notice a hinge line or umbo if this is a bivalve, but this may be due to the deteriorated condition and the fact that I am a rookie at this. It appears to be broken in half, with the inside showing black sheeny layering. I appreciate everyone's help on this! Link to comment Share on other sites More sharing options...
Pterygotus Posted May 5, 2020 Share Posted May 5, 2020 Definitely not a tooth. Concretion maybe ? Link to comment Share on other sites More sharing options...
GeschWhat Posted May 5, 2020 Share Posted May 5, 2020 Wecome to the forum! It looks it could be a cone-in-cone structure, but wait for the experts. Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
