Miocene - Pleistocene Deposit Fossils Sc: Osteoderms, Teeth, And Fish Parts?

[TheAshBee]

Hey Fossil Forum!

I've spent some time in the background IDing some of my own specimens, but now I'm coming out of the woodwork to share some of my own questions. These specimens were collected in SC in a Miocene through Pleistocene deposit.

Specimen #1: (Is it an osteoderm? Or just phosphate?)

Specimen #2: (THIS one seems to be an osteoderm!)

Specimen #3: (Is this just enamel from an Equus sp. incisor, or is it something else?)

End views:

Specimen #4: (Is this a reptilian tooth? I've never seen anything like it...)

Specimen #5: (We were told these things were material from fish of some kind...)

I appreciate any assistance you experts can provide!

Some of your number 5's look like sea robin skulls to me?

Any Cretaceous in the mix there? I ask because #4 reminds me of Cylindracanthus.

[TheAshBee]

Auspex,

You may be correct about #4 as Cylindracanthus. Were they only in the Cretaceous? I saw some others that said Eocene...

Thanks for the lead!

Really? We have a whole container of sea robin skulls and these things are definitely distinct.

I am by no means any kind of expert, so take this with a grain of salt. I agree with Lissa, they may not be sea robin skulls pieces, but they do resemble some type of fish skull parts...just what fish I have no idea. Nice finds, by the way!

Maybe Tilly bones?

Ahhhh....Tilly bones did not even cross my mind! We might have a winner!

Aha! You are correct! Thank you for the ID!
