Large Fossil Dinosaur Tracks / Eubrontes & Anchisauripus / Massachusetts
Age: 200 Million Years Old
Location: Connecticut River Valley, Massachusetts
Species: Multiple Theropod Species (Juvenile Eubrontes, and Anisauripus)
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 at least two species when comparing the size and shape. I wonder where they were off to?
Eubrontes ("True Thunder")
These tracks were made by a large, bipedal, carnivorous, Theropod dinosaur similar to a Dilophosaurus and are among the most common tracks found in the valley. These dinosaurs probably reached a length of 20 feet .
The animal that made these Eubrontes tracks was one of the first large meat-eating dinosaurs . Scientists studying these tracks have compared the tracks to the foot skeleton of the well-known dinosaur Dilophosaurus . They have noted that the foot skeleton of the Dilophosaurus seems to fit nicely into these footprints . Thus it is likely that an animal similar to the Dilophosaurus made the Eubrontes tracks. Dilophosaurus is best known for its role in Jurassic Park , where it ate the computer expert in the jeep. It's the valley dinosaur that went to Hollywood and made it big.
Anchisauripus ("Close to Lizard Foot")
These tracks were made by a medium-sized, bipedal, carnivorous, Theropod dinosaur similar to a Coelophysis . This dinosaur probably reached a length of 7-10 feet.
Skeletal remains of an animal similar to Coelophysis have been found in the valley supporting the conclusion that it was like a Coelophysis . These tracks could have been made by the adult version of the dinosaur that made the Grallator tracks.
All of the tracks are Raised impressions 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. The sealant May be washed or peeled off so the fossil can revert to its original state.
Epoxy can be added around the border for added support and strength upon request.
