Hello! I found a mysterious fossil bone while looking for shark teeth in NE Mississippi this past weekend. I believe it is from the Eutaw Formation which is Late Cretaceous. This bone appears to be complete, although maybe a bit creek-worn. It is as hard as a chert creek rock with visible minerals present in the pores. Size is 2.75" long, by 2" wide, and around 1.5" thick (including the arches on the other side). I have not studied vertebrates, and have no idea how to technically describe bones, but it looks like the largest surface is a ball (like a ball/socket) and there are two areas on either side that look like contact points. If you turn it over, it is almost heart-shaped with another ball-type surface at the bottom of the "heart shape" and two concave areas on the sides (lots of mineral "stripes" in this area). At the top of the heart shape, there is a dovetail-shaped notch. I am more than happy to take additional photos if requested! I've scoured Google and can't find much to go by, but I am guessing that it is probably some kind of marine reptile or less likely, a dino that had washed out to sea. I know it is a stretch to be able to identify one lonely little bone, but I would love to know anything I can about it, no matter how general. Thanks everyone!!!
