Trimmers Rock finds from Danville PA

[PHFossilGuy]

Found these specimens when hunting just outside Danville, PA in a roadcut near the Susquehanna river. The location is Trimmers Rock formation. I'm fairly certain that these are brachiopods but I haven't been able to ID them with any certainty. Mainly at that site we find beautiful Mucrospirifer specimens. However, these specimens appear larger and don't, to me, seem to be Mucrospifier. 

 

Most of the research I've done has yielded IDs that seem to be typically smaller than what I found. The first image shows the two parts together, the second shows them side by side with the top piece flipped over, the third shows the bottom piece and the fourth shows the top piece. My best guess is Leiorhynchus.

Thanks for the reply! Rhipodomella was something I considered for that one imprint but I thought maybe my find was too big (about 3 cm across). I just saw your Rhipodomella penelope Growth Series post. That was definitely enlightening. 

 

As far as Tropidoleptus carinatus, that seems to make sense. That imprint is just over 3 cm at the widest part. That imprint (circled on the left) is the imprint for the cast circled on the right.

Here's the imprint and matching cast close up.
