It doesn’t look like a tusk or tooth to me, since it seems lack enamel and also seems to be porous.

It looks like an iron/sandstone concretion to me, I’ve found some similar things here in SW FL.

Due to the difference in locality, I’m not able to say for 100% certain though…

Cheers…

Looks like half of a black walnut shell to me…

…but I could be wrong.

I second what Victor Perez said.

Looks like a great white shark tooth to me.

Carcharodon carcharias.

I belive that what you have found is an upper mouthplate of a drum fish.

I would lean more towards modern, than fossil.

…but it’s still a really interesting piece!

Due to the size, I would say deer rather than camel.

It looks like oyster shell to me…

Mostly due to the layered appearance of the (possibly broken) edge.

It’s still a fossil, and therefore still cool though!

Thank you for sharing!

It doesn’t look like coral to me, either…

I would lean towards bryzoan or sponge.

…but invertebrates are my weakest link in identification, so I may be wrong.

From what I can see, it does look like a whale tooth…

I am attaching a photo of a whale tooth in my collection from the phosphate pits of “Bone Valley” FL (Around Polk and Hardee counties) for comparison.

Not all whale teeth are “robust”

Second photo is too blurry to see anything.

Could you post more pictures?

Thx

It looks like a partial Peccary molar to me…

Hope this helps.

The first one looks kind of like calcite to me…

…and the others look like Quartz, maybe with some Limonite (Iron Oxide)

The third photo makes me think that it may be a really beat up fish ballast bone (tilly bone)…

I would also agree that it is probably not a tooth, since I see no enamel…

Hope this helps!
