Show us your Missisipian or later trilobites!

As we all know, the trilobites were on their last proverbial legs coming out of the end-Devonian extinctions, their numbers having dwindled to a lone order, Proetida. I haven't seen a lot of talk about these last few survivors of the trilobite lineage, so I wonder how many of us have one of these survivors! I personally don't, but I'm interested to see the forum's contributions!

Every single fossil you see is a miracle set in stone, and should be treated as such.

Heres one of my local favorites. A nice enrolled and prone Ameropiltonia Lauradanae trilobites from the Missouri Chouteau Formation.

Heres another Missouri trilobite. Decently rarer than its relative above, it's a Comptonaspis swallowi! This trilobite lacks the ornamentation on the cephalon that the piltonia have, and can typically grow a little bit bigger. This trilobite also comes from the Mississippian Chouteau Formation as well. Locality specific for this one was Saline County, MO.
