This is indeed a Trilobite. it is the fragment of a Ptychopariid trilobite. If from thw Wheeler Shale FM, This is big enough to part of Asaphicus wheeleri.

this is a felxicalymene ougzi (definitely butchered the species name) from the Ordovician-Silurian rocks of morocco, Africa. It is a very common trilobite from Africa.

If you have dental tools I would use them too. Don’t pick too hard though.

It’s definitely Eocene. Possibly Upper Eocene (Pribolian Stage).

I wouldn’t soak it in any chemicals. The specimen seems have cracks. I would use water and glue. You could also mix water and glue together to stabilize the specimen. The fossils is an Echinoid (Sand Dollar). Possibly Periarchus sp.? I am to too sure without a locality/formation.

i have so much to post there!

Bull shark?

oh wow very nice set up! i love the idea!

drool!

Where was this specimen found?

It is most likey Ordovician. There are outcrops of the Chickamauga Limestone in that region that is Ordovician in age. It’s a Horn coral from the Chickmauga Limestone. I would have to do a bit more searching to narrow it down to genus level.

Asphelaspis brachyphasis from the Conasauga Shale.

If it was found in GA. It mignt be Ordovician. There is more of that then Devonian rocks in GA.

Looks to be horn coral possibly Devonian? Where was it found?

Asphelaspis brachyphasis are the names of the trilobites you have found. They are very common. So common they have their own zone. They were first know from rocks in Nevada. You are in the Middle Cambrian portion of the Conasauga Shale Formation which is ~497 million years old. This is the younger portion of that rock unit. The other portion is…[Read more]

These are Asphelaspis brachyphasis trilobites. Middle Cambrian.
