2 years, 1 month ago2 years, 1 month agoHonestly, some parts of it look like a limestone or dolomite and other parts of it look like chert. It may not be from the Avon Park Formation, but it could be from a unit that is the same age in Alabama. This website mentions the “Claiborn/Jackson Group” which include “fossiliferous chert and limestone boulders”.…[Read more]

2 years, 1 month ago2 years, 1 month agoI think this is a chunk of dolomite, possibly from the Eocene Avon Park Formation. The molds/impressions seem to mostly be bivalves, but the second photo you posted looks like a partial echinoid (sea urchin). I don’t know the invertebrates well enough to give you any species names.

Victor Perez replied to the topic Fossil- Vetebral Body from what? in the forum What Is It? 2 years, 3 months ago
2 years, 3 months ago2 years, 3 months agoHi Todd,
My best guess would be that it is either an ichthyosaur or dinosaur vertebra, given that the Cretaceous interior seaway cut through Phillips County, Montana.
There is a small museum you could visit/reach out to for more information: https://mtdinotrail.org/phillips-county-museum/
Best,
Victor

Victor Perez replied to the topic Are these teeth? in the forum What Is It? 2 years, 4 months ago
2 years, 4 months ago2 years, 4 months agoI don’t think they are teeth. It looks like you’ve got a conglomerate, which is a rock composed of rounded grains of varying sizes.

2 years, 4 months ago2 years, 4 months agoHi Nathan,
This tooth is from an extinct mackerel shark, Otodus obliquus. It is likely around 60 million years old and is the ancestor of the popular megatooth shark, Otodus megalodon.

2 years, 7 months ago2 years, 7 months agoI don’t really know what you mean by real or fake. It’s a real rock… Specifically it’s chert (a variant of quartz).
