The tracks may also be from a plateosaurid. In 2016 Molina-Perez and Larramendi based on the 45 cm (1.48 ft) long footprint estimated the size of the animal at 8.4 meters (27.5 ft) and 600 kg (1.323 lbs). Another 60.5 cm (1.98 ft) long footprint belongs to an 8.1 meter (26.6 ft), 1.1 tonne (2.425 lbs) individual, that was very similar to Sinosaurus triassicus. Another major find occurred at Rocky Hill, Connecticut in 1966. Nearly 600 prints are preserved there in an area now designated Dinosaur State Park. A trackway attributed to the ichnogenus "Eubrontes" had a missing second digit on the right foot. The animal could have either lost the toe due to injury or it was malformed. In early 1970s, a fiberglass cast of an "Eubrontes giganteus" footprint was made by Paul E. Olsen, then 14 years old, and his friend Tony Lessa. On June 29, 1972, it was sent by Olsen and Lessa to President Richard Nixon to get his support for registering the Riker Hill Fossil Site in Roseland, New Jersey as a National Natural Landmark. In 1991, "Eubrontes" was named the state fossil of Connecticut.
