I’m hoping someone will identify these fossils for me. I received a macro lens for my iPhone, and have been noticing a lot of tiny fossils on the rocks around my yard (Middle Tennessee, Mississippian, St. Louis Limestone & Warsaw Limestone). In the second photo, I have zoomed in on the object which has caught my eye. There are several like it on the rock. Can anyone tell me what it is?

Now You are really lost!! :rofl:  Microfossils are a whole new world of adventure.:thumbsu:

 

I think Your piece is a conularid, but am not sure I got the right word there.

I'm guessing the tiny straight rods could be sea urchin spines. They can be locally very abundant in the Mississippian Monteagle limestone in your area.

In the first photo the 2 small items look like broken juvenile horn corals.

Totally agree with sea urchin spines for second photo.

Alright, thanks again! I googled fossilized sea urchins. Cool looking little things! :)

I've never seen a spiraling evolvement on echinoid spines, but I can imagine a bryozoan with that feature, like Archimedes . :)

Hmm. Alright, thanks! :) So many of the fossils I see while searching online look much the same to me. :wacko:
