Yesterday I was in a creek that I haven't been to in a while. I got the normal fossils, mainly shark teeth and the occasional meg frag or mako, but I also got these strange fossils that I have never seen before. The first one reminds me of a dolphin ear bone we got earlier this year, so I was wandering if it was some sort of ear bone.

The second fossil I am very curious about. At first I thought fossil barnacle, but it appears to have enamel on top. The closest thing I could compare it to was a stingray dermal plate I saw in a book, but the bottom of mine seems more raised and the top seems less slanted. My only other guess would be fish tooth, but the flat bottom turns me away.

Most likely from a ray.

I agree with ray dermal denticle.

It does appear to match the bottom right fossil.

I have been offline for the last week, but I notice that we have nothing on the first fossil, any other ideas?

This looks like a sawfish barb to me, but I'm no expert

The root looks similar.

Florida sawfish rostrum are much less barb-y, and that's definitely a ray dermal denticle!

Fossils? I dig it. :meg:
