Trilobite in limestone, along with some bits of crinoid stems.

I love the way you go into detail regarding the environment the trilobite lived in through the information you gather from one rock!!
You’d be the BEST geology teacher ever 👍🏼👍🏼👍🏼

[briancurtis]

Gotta be a trilobite. And if it's a fossil, that means it's sedimentary, probably marine limestone.

I miss the desert in its various hues of emptiness. And the smell of greasewood after the rain has beat the dust down.

[jaywoods]

There is a circular section of a crinoid stem on one of the short sides. But why is there so much red and yellow (iron oxides?)?

[ericclayton]

It is a trilobite section, my clue was another in cross section on the side of the rock.

[krakhedd]

Looks like a trilobite fossil! And I think the area you're in used to be shall salt water, so, that's my guess and I'm sticking to it

[brown-eyedman]

0:38 and Im guessing limestone and a trilobite.

[cedarwaxwing]

It’s a trilobite fossil in a muddy limestone.

[ercieyyy]

I guess that it is a kind of clastic sedimentary rock with maybe having carbonate content cuz its silt-sized grains are visible to the naked eyes. Try to pour some HCI acid to identify whether it contains carbonate minerals.

[erikhinds-cycx]

I think it’s limestone or chert. Cambium period. Fossil is some kind of mulusk.

[beeamerica]

From what I can see it looks like Micah. limestone fossil
