Bugs and more. If anyone can give specifics on what we found it would be great.  This was a first time experience for my girlfriend and she found a nice curled bug she worked out of the rock.

 1. Can you please post some clearer photos of the first trilobite? It would greatly help in assigning a definitive genus to your specimen.

 

2. The pygidum is certainly of the Family Acastidae (Order Phacopida), matching the description of Greenops.  

 

3. As for the cephalon, the shape of the glabella points to the Devonian period Homalonotid trilobite Dipleura dekayi. 

 

4. This appears to be an isolated and fragmented spine or pleura, which I cannot conclusively identify.

"Trilobites survived for a total of three hundred million years, almost the whole duration of the Palaeozoic era: who are we johnny-come-latelies to label them as either ‘primitive’ or ‘unsuccessful’? Men have so far survived half a per cent as long."  - Richard Fortey, Trilobite: Eyewitness to Evolution.

Nice finds! Love a nice trilo:trilo:

agree with everything @Douvilleiceras Said except the last might be a brachiopod mold. I'd say greenops is rather safe for the pygidia.

Happy hunting,

I agree with the others. 

1st one is either an Edredgeops, or Greenops. - Would need to see a cephalon or pygidium to be sure. 

2nd one is  a Greenops pygidium. 

3rd one is a Dipleura dekayi cephalon. 

Last one is a pleura from a Dipleura dekayi

Neat finds.  :)

Where were these found and what size are they?

Congratulations on the successful hunt!

They are from seven stars Pennsylvania. The first one is about a half inch. The second is about a third of an inch. The others are about 1.5 inches

The last one appeared to be attached the one before it until it broke trying to free the matrix.
