ChrissyG45 Posted August 2, 2022 Share Posted August 2, 2022 Can anyone ID this type of rock? Link to post Share on other sites
Kane Posted August 2, 2022 Share Posted August 2, 2022 It looks to be a brachiopod impression, but the photo is very blurry. I do not think this is basalt, but likely a weathered piece of sedimentary rock. 3 Link to post Share on other sites

ChrissyG45 Posted August 2, 2022 Author Share Posted August 2, 2022 Thanks so much- been picking up lots of rocks to identify - thought this one was neat with a divot in it! I didn’t notice the impression until I got it home! Appreciate the help. 1 Link to post Share on other sites

The overall shape of where the beak would be suggests more of a brachiopod to me, but only better pictures can tell! Link to post Share on other sites
Plax Posted August 3, 2022 Share Posted August 3, 2022 maybe a cardium impression in sediment that has been tumbled and phosphatized in a lag. Link to post Share on other sites
