Usually I can ID my own fossil insects but this one is difficult for me. I would like to think it is a stilt bug but the neck is a bit long, and the antennae have a joint closer to the head than what a stilt bug usually does. I thought that it could be the water bug, Ranatra fusca but there is no breathing tube out the back end and this fossil and another just like it have wings. Any ideas? It is possible features look different because it was distressed when it was buried in the silt that later became shale.
