Cambrian Arthropod Trackway Fossil from Vermont

Description: This trackway looks like some ascribed to trilobites, but may have been made by some other arthropod. The sides of the trackway are completely parallel, almost like some Cambrian Lionel train set. The detail is quite good, with the specimen affording a most unique opportunity to own a moment in time frozen for over 500 million years. See my other offerings for an example made by a less coordinated arthropod , as well as one from the Carboniferous of Tasmania.
