16.5" Shale With Two Dinosaur (Eubrontes) Footprints - Massachusetts

Shale With Two Dinosaur (Eubrontes) Footprints - Massachusetts #306620

This is a pair of dinosaur footprints, collected from the Jurassic-aged Portland Formation of Massachusetts. Based on the toe size, spread, and shape, this would be a Eubrontes giganteus trace fossil. Eubrontes is not the genus of the dinosaur, but instead the name of this dinosaur's footprint. The type of dinosaur that left the footprints has yet to be determined, however it's widely believed to be from a carnivorous theropod.

The impressions have been darkened, likely with a sealant.

It comes with an acrylic/metal display stand.

In 1991 the Connecticut state legislature designated fossil, theropod dinosaur tracks found in the Connecticut Valley as their state fossil.

The Connecticut Valley is home to the first dinosaur tracks identified in North America. Thousands of tracks from several different types of dinosaurs have been discovered in the Early Jurassic aged sandstone on the valley floor. The most abundant of these tracks is a three-toed, theropod dinosaur track which ranges from about 16 to 20 inches long. Over two thousand of these tracks were discovered in a single layer of rock in Rocky Hill while doing construction on a highway. While no skeletal remains of this dinosaur have been found, it was named Eubrontes giganteus in 1845 by famous paleontologist Edward Hitchcock

Based on size, shape and stride it’s believed the dinosaur that left these tracks much has over one meter high at the hip and 5-6 meters long. Based on these characteristics and their age it’s possible they may be related to Dilophosaurus, but that’s mostly just a guess.
