This is a very nice dinosaur trace fossil. Dinosaur tracks have been chosen as the State Fossils of Massachusetts. ( concave footprints ) sought by many collectors and it wonderfully exhibits the three-toed nature of the dinosaur’s foot and some footprints are crossing over each other that would indicate that two different animals walked in the same area . The tracks have been slightly darkened for contrast and is extremely well showcased on the plate of matrix. This is a striking example of a collectible dinosaur tracks that would display well on a shelf or in a display case and quite rare as we don’t get many tracks like this one.
Grallator is an ichnogenus (form taxon based on footprints)( and is thought to be the Coelophysis Dinosaur or Raptor like ) which covers a common type of small, three-toed print made by a variety of bipedal theropod dinosaurs. Grallator-type footprints have been found in formations dating from the Late Triassic through to the early Cretaceous periods. They are found in the United States, Canada, Europe, Australia and China, but are most abundant on the east coast of North America. The name of the footprint is not the name of the Dinosaur, but was probably COELOPHYSIS Dinosaur !!!!
Grallator tracks were made by a theropod (carnivorous) dinosaur such as Coelophysis. These tracks have been well-developed claw impressions on two of the toes. This track has been highlighted., The tracks are concave footprints ( see diagram above to see how footprints are made and fossilized).
Also you see a picture that shows you Turkey Tracks in the snow that I photographed 3 winters ago , does it look amazing that the dinosaur tracks look similar to the turkey or a dead ringer for the turkey tracks there’s only 200 million years separating them !!!!!!!!
