Ok, so this may seem strange, but I'm trying to utilize every resource available. So I am normally part of the fossil forum, and someone who hunts for fossils in Maryland (as do I) found this fossilized critter. I thought it looked like an isopod, so I contacted some people, most of which have not responded. Isopod would be shaky as there is debate as to whether they have evolved at the date of this fossil. Another possibility is bristletail or silverfish. This bears close resemblance to the specimen. A leg is also present. For more information ad pictures: http://www.thefossilforum.com/index.php?/topic/74597-help-with-arthropod-id/&page=2#comment-792948
I can try to provide it.
Thanks for the help!
