The locality of this fossil was 5 minutes from the Ross Formation in Tennessee. My professors believe that this is a trilobite that has undergone replacement. Specifically the Shepard's Hook Trilobite.

This is the prep I just finished of Bothriolepis canadensis (Placodermi; Upper Devonian). The concretion was collected in 1966 and never prepped. Because there was not much surrounding matrix, I prepped the whole thing (dorsal and ventral surfaces). I made a formed cradle out of paleosculp for prep and for storage, as the skull is compressed and potentially susceptible to breakage while handling. This is how the concretion looked prior to prep (left is dorsal, right is ventral): I started prepping the ventral side first (I didn't know when I started which side was which). Here is a series of photos showing the prep of the ventral side: Here is a series of photos showing the prep of the dorsal side. A portion of the left pectoral fin, complete with marginal spines, is present. The anterior part of the orbital is intact. I think the large raised piece toward the rear of the skull is the nucal plate that has been dislodged. If one were to spin that around and place it towards the front of the skull, it would make up the posterior of the orbital. I think the mouth opening is also intact on the ventral side. Here is a composite photo showing before and after prep of both sides.

Hello everyone, I just got back from collecting some fossil sites in Pennsylvania yesterday. Among these was a Catskill Fm. site, while the fishy finds there weren't particularly plentiful, I did manage to find some other interesting stuff. While there I found these rocks which have unevenly spaced lumps scattered across the surface, on the other side the position of the lumps corresponds with round impressions in the rock. I initially thought this may be something like a layer full of concretions but with the dips on the other side of the rock I was wondering if it may be some kind of ichnofossil? If anyone has any ideas as to what this may be, I'd love to hear it, Thank you for looking! In the field: A closer look at the sample I took with me:

Unidentified fish tooth - possibly sarcopterygian. Catskill Formation Metzgers' Quarry, Canton PA. Upper Devonian. This is actually an imprint of a tooth, with a bit of the enamel/bone material (white,pink,blue) left behind in the imprint. Tooth itself was destroyed in the splitting process, as it was not visible at first. Oh well.© 2021 T. Jones
