MeargleSchmeargl Posted October 21, 2019 Share Posted October 21, 2019 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! 3 Every single fossil you see is a miracle set in stone, and should be treated as such.

Jackson g Posted October 26, 2019 Share Posted October 26, 2019 Heres one of my local favorites. A nice enrolled and prone Ameropiltonia Lauradanae trilobites from the Missouri Chouteau Formation. 7 Link to comment Share on other sites More sharing options...
Jackson g Posted February 5, 2020 Share Posted February 5, 2020 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. 3 Link to comment Share on other sites More sharing options...
