ID help for two Trilobites I found...

[snakebite6769]

Okay, so I had some free time while I was working in the mid Atlantic States so I decided to sneak in a quick collecting trip to Virginia. I’m hoping someone can tell me what type of Trilo this is before I prep it out. It’s my winter project  

i also have a question on ID for another Trilo imprint I found earlier this summer but haven’t had a chance to post it. This one is from New York, it was a random road cut that I stopped at to have some lunch and happened to notince these in the rocks....of course I brought them home! Pictures to follow

These are the two pieces from New York

Rob, 

Any specifics as to where in New York, and in Virginia these were found?

We need additional prep and a locality for the trilobite from Virginia.

The New York pygidium matches well with: Odontochile micrurus

Tim, I can’t give the specific location in New York only because im the only person with access to the location. It is near Lang’s quarry, that much I can say  because I found it looking for spots to find Eurypterids. The Virginia one is from  hardy county West Virginia

West Virginia is an entirely different kettle of trilobites.  Thanks for clearing that up!

Your welcome, under the West Virginia one, the rock split during transport. This might give a better guess as to what this Trilo is....

Excellent, that solves this mystery.  This trilobite is from the Needmore Formation: Coronura aspectans

that was what I was hoping it was, thank you for the clarification. This is a new one for my collection just like the above one from New York.

I just have to say wow, piranha, you have quite an eye for this.
