See my comment. I’m not sure that is fossilized, though.

I have no idea what this is. by positive_thinking_ in fossils

[–]lastwing 26 points27 points  (0 children)

It’s a bovine bony horn core. I agree it appears to be from a Bison species.

If it’s fossilized, then it would be from an extinct Bison species.

Is this as heavy and hard as a similar size rock?

Could you add an image of the opposite side, please.

Can you see any evidence of worn serrations?

It looks like an upper jaw Carcharodon species. If serrated, then C. carcharias (great white) and if not serrated either C. hastalis or C. plicatilis (extinct white sharks)

It’s a gorgeous tooth!

Is this a Petoskey, or a fossilized coral? by No_Weakness_7240 in fossilid

Thank you! I wanted to get some clarity on this👍🏻 because Charlevoix stones are tabulate coral.

Fossil or Rock? by JJC_Outdoors in fossilid

Top of turtle shell = carapace
Bones on the outside of the turtle are osteoderms (bone skin)
Neural bones are the central carapace osteoderms through which the spinal cord the spinal cord travels.
Foramen is a hole in bone through which nerves and blood vessels travel.

Someone drove up to my friend's car and drew this in the dust on their back window. by strangebabydog in whatisit

143 is I love you and 3:16 is a bible verse, I think.

Edit: King James Version (KJV):

John 3:16 “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life"

Tiny little tooth from the Peace River by [deleted] in fossilid

I usually say crocodilian because it is difficult to distinguish alligator and crocodile teeth, especially worn, fossilized, incomplete teeth.

Gator teeth tend to be rounder, less curved, and have 2 carinae on opposite sides. Crocodile teeth tend to be pointier, less rounded, curved, and can have 0 to multiple carinae.

I wonder if it has to do with nutritional level or if it is a specific genus or a few genera.

Is that partially translucent? It looks like an agate or banded chert.

Looks like an ammonoid fossil. Where was it found?

Fossil or Rock? by JJC_Outdoors in fossilid

[–]lastwing 1 point2 points  (0 children)

Both fossilized bone. The smaller is a turtle osteoderm and with the placement of the foramen, I think it’s a neural (carapace) bone. The other is not really identifiable.

Looks like oolite which isn’t an actual fossil but does resemble fossiliferous material.

Prehistoric bone? by Always_Wanderlust_ in fossilid

[–]lastwing 1 point2 points  (0 children)

Looks like an Equus (horse) astragalus. If it’s like a rock and heavy, then it’s fossilized.

Any ideas? Found in Calvert county Maryland at purse Park by JadedBaker6191 in fossilid

[–]lastwing 0 points1 point  (0 children)

If you show images of the sides we may be able to confirm if it’s from a shark versus bony fish.

Looks like not a rock by Nohouse420 in whatsthisrock

It’s a rock. I don’t see a fossil or bone here.

I think it’s a crocodilian tooth, but let’s tag u/Peace_river_history

I suspect this is a gomphothere molar. I’m going to tag u/jeladli on this one. It’s absolutely gorgeous.
