My Keokuk Limestone finds from this fall have now been cleaned and identified. I am struggling with a few and am reaching out for any suggestions to identification. Thanks!! 1. First up is a blastoid that can't be matched well with the three species to occur in the Keokuk. It is probably a weathered sample that makes identification tough for me. 2. A crinoid cup that I do not recognize. It is very round and smooth. Maybe it isn't a crinoid cup! 3. A second crinoid cup I can't identify. 4. A large gastropod that spirals backwards to most gastropods. Reminds me of Maclurites if this was Ordovician. Straparolus looks similar but spirals normally. 5. And finally a specimen I thought was a fenstrate bryozoan until I looked closely and saw it lacked the netted appearance. Maybe a dendroid graptolite?

@CabinetOfCuriosities recently posted a Devonian bone for identification. Having just read the post, I headed downstairs and split open a piece of matrix from the fish layer of the upper Burlington, lower Keokuk Formation and a boney looking fossil presented itself. What a coincidence! It vaguely mimics turtle remains I have found in Florida. Thoughts of what this is are welcomed!!!!!! By the way, the size is 2.5 by 2.0 cm.

This week, I took the time to break open the 6 chunks of matrix I had brought home from the Mississippian Burlington Limestone from a trip this Fall. My finds were not as good as other trips but it is always exciting to see what pops out of these rocks. My identifications are going to be educated guesses at best. I am not versed very well in Chondrichthyan recognition. The pictures 1,2 and 3 look like teeth but I can not find images that fit their looks. Could they be dermal appendages??

Here is another black mass that emerged from the light colored matrix of the Burlington Formation. Pareidolia has me envisioning a tooth with the enamel peeled away on top and side projections. If it wasn't so fragile, I would prep around the other side. This measures just under 2 cm.

Here is a post prep picture of Platycrinites found on a early July fossil hunt in SE Iowa (see previous trip report). These crinoids have a columnar stem with a twisted pattern, making them very interesting. My daughter can't look at it without thinking tapeworm. I have to somewhat agree but still see the beauty in this crinoid!!

I tried my darndest to ID these fish teeth from the Burlington/Keokuk Fish Beds of SE Iowa. Unfortunately, these beds have been known since the1800s but no scientific literature has been printed since then UNTIL 2017 when our own Fossil forum Member, @Elasmohunter presented a paper for his thesis. So not much info out there. Here are my finds. I am not sure of the IDs on most of these. Each picture has a red number to respond to. Thanks Mike Also what am I doing wrong having extraneous pictures always added at the end of my posts ( as in the ones below). I delete them and close but they reappear!
