Mandible, or suspiciously mandible-shaped shell?
Hi all!
Found this a few years ago when I was visiting the Keys with my family. Everyone has debated on if it’s a lower jaw or a shell.
I’m not entirely sure to be honest, though I lean more towards shell. In the case for mandible, the overall shape is very… mandibular? lol. The holes on the superior aspect look like they could be alveoli, and there could possibly be something of a mandibular condyle as well.
In the case for a shell, the wavey texture on one side is very much not bone like. In the areas where it is broken, it also looks like a shell, in that there seems to be layers.
Wanted to get everyone’s opinion before I do the tongue test… (joking)
