Another week, another batch of new images produced on my home-based Magnify2 imaging system from GIGAmacro.
Leptaena brachiopod in (Mississippian?) limestone from Montana:

Here’s the flip side of the same sample, with a lot of fenestrate bryozoans to see:

As always, enjoy exploring them for details.
In the 1st two photos of the Mississippian Montana limestone, there’s a nice encrusting bryozoan (like Fistulipora) at the bottom of Photo No. 1. On the shot of the other side in the 2nd photo, besides the fenestrate bryozoans, there are some branching, Cystodictya-type bryozoan fronds, on the right side. Plus, on this side there might be an ostracode, perhaps trilobite debris (both sides), and a crinoid columnal. Sorry, but it’s been awhile since I got to play in a Mississippian “garden” again. Miss those critters, and their pals.
