Recently and legally collected in private property along the Connecticut River Valley. This is the fossil impressions of a Theropod (raptor) that existed some 200 Million Years Ago. The species that made these tracks is relatively unknown to science, but it can be said safely that these tracks were made by theropods standing at about 5 to 7 feet tall.
There are Raised impressions on the back which are created when new Sediments cover the original impressions and harden within them. On occasion when you split this Jurassic shale, you will get both the original negative impressions as well as these Raised casts. These tracks have been lightly polished with a clear sealant to help pop them out, though a few tracks remain unpolished as to not create a blurry mess. The sealant May be washed or peeled off so the fossil can revert to its original state.
