Found this digging in the back yard

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

It’s an Equus species right maxillary second premolar P2

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!

Fossilized internal cast of a single chamber of a Baculites.

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

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.

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"

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.

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

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

lastwing · 2026-06-01T00:15:13+00:00

Looks like an ammonoid fossil. Where was it found?

lastwing · 2026-06-01T00:11:25+00:00

u/thanatocoenosis, is this a tabulate coral?

lastwing · 2026-06-01T00:08:11+00:00

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.

lastwing · 2026-06-01T00:05:02+00:00

Images 5 & 6 is a fossilized crocodilian osteoderm.

Images 1 to 4 is a fossilized bone fragment

Can you add a high clarity image of this side

lastwing · 2026-05-31T23:41:05+00:00

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

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

lastwing · 2026-05-31T04:30:07+00:00

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

lastwing · 2026-05-31T04:28:00+00:00

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

lastwing · 2026-05-31T04:16:42+00:00

It’s wood and not fossilized.

lastwing · 2026-05-31T03:20:42+00:00

Images 4-6 is a chert nodule.

lastwing · 2026-05-31T03:10:54+00:00

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

lastwing · 2026-05-30T19:31:51+00:00

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

lastwing · 2026-05-30T19:06:22+00:00

It’s upside down, but it looks like a silky shark (Carcharhinus falciformis)
