Species: Multiple Unknown Theropods and large Prosauropod
Recently and legally collected in private property along the Connecticut River Valley near Middletown, CT. This is the fossil impressions of a Theropod (raptor) that existed some 210 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. The large Prosauropod likely stood at 12-16 feet tall.
Prosauropods were large semi-quadrupedal, herbivorous dinosaurs of the Triassic and Early Jurassic. Found on most continents, their fossils are considered to be some of the world's oldest discovered dinosaur bones. Their name "prosauropods" means "before the sauropods", and refers to the belief that this group is ancestral to the Sauropoda. They are usually classified as an infraorder of Sauropodomorpha, which includes the sauropods and belongs to the larger group Saurischia. The Prosauropods includes four families: Platesauride, Anchisauridae, Massospindylidae, and Melanorosauridae.
One the back are Raised impressions more theropods. Raised casts 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 polished. The polish can be scrubbed off with a little elbow grease.
