MrBones Posted October 3, 2021 Share Posted October 3, 2021 Hello! I found this very odd fossil while scratching on Jebel Hafeet, Al Ain, United Arab Emirates. I came across it while brushing sand off of a layer of compacted sand. The fossils are eocene in age. I have found many urchins in the same location (including Schizaster and Echinolampas ovalis?). At first I thought it might be a tooth, since the exposed side looked similar to the backside of a crocodile's tooth, but upon further inspection I noticed that the fossil had a thin, asymmetric covering. This made it look more like an unpopped popcorn kernel. I hope you'll be able to make sense of this for me! Link to comment Share on other sites More sharing options...

The evident concentric layering is what makes me think 'concretion' right away. It's an interesting geologic oddity; I'd have picked it up myself. 2 3 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

The contours and texture of the other side misled me then. It is beginning to look it. Link to comment Share on other sites More sharing options...

It's an interesting geologic oddity; I'd have picked it up myself. I appreciate the response. It sure is interesting, but I'm still not 100% convinced though. The middle "shell" appears to be slightly oblong. And also has a more or less clean "break" where the thin layer turns white. It also appears to be off-center, and almost touches the outer shell on the one side. I also want to make it clear that I used paraloid to hold the sand in place. The sand inside of the object looked about the same as the sand covering it. I am not an expert, especially not on concretions. Maybe this additional information would even further support the concretion id. Link to comment Share on other sites More sharing options...
