Is this some sort of tooth or a spine? While investing the trace fossil I presented in the post a few days ago with the microscope, I noticed this brown-amber colored object. My cousin suggested it might be part of a conodont. Rock plate was found in Carroll County, Kentucky in the Kope Formation of the Ordovician Period. All images on this page are at 40x magnification with a microscope.
This last fossil might be some sort of coral. I magnified thinking it might be a bryozoan that are common in the area but the pores look too big.
