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. While the tracks themselves are called Grallator Tracks, they were likely created by Podokesaurus Holyokensis. The reason why the tracks have a separate name is because the tracks were discovered before the first remains of Podokesaurus. The track spent some time in the Connecticut River and has been naturally tumbled to create a beautifully smooth surface. There are also fossil insect burrows all over the specimen.
one the other side is a rather large positive impression called a Eubrontes. This track was likely made by 10-12 foot Dinosaur, possibly Dilophosaurus.
This track has been lightly polished with a clear sealant to help pop them out. The sealant May be washed or peeled off so the fossil can revert to its original state.
