Please help six-year-old fossil enthusiast ID our fossils

[ebell545]

We found our fossils in a creek bed (Fishing Creek) near Loganton, Pennsylvania. This is a very interesting area with karst topology, limestone, and lots of sinkholes. In fact, the creek, seasonally dries up, emptying into several sink holes. We found several interesting rocks, but the first was one with a shell or a trilobite. We also found another rock nearby in the creek, potentially imprint fossils/worm holes? Please help us identify, we would be so thankful!

The first photo appears to have a brachiopod in it. The rest may be ichno (trace) fossils.

I don't know of any brachiopods with lace like this. In the first picture i think maybe the under view of Cryptolithus "tesselatus", this Upper Ordovician trilobite fit with Pennsylvania Geology. 

 

I don't have much experience, so I'll let other more experienced users decide.

I'm going to say/guess the first one is a horn coral. The traces could be Planolites. There are other ichnogenera that look similar though.

The adjustments help to bring out the shape. I have to agree with trilobite now.

I'll go along with that too.
