Mystery Track

Another submission in the great Mystery Track Challenge! Lars' only clue for you was that I photographed these tracks yesterday in Holyoke, MA in the Connecticut River Valley. What species?


  1. Don't rule out anchisauripus sillimani or grallator cuneatus.

  2. You two are too good. The photo is from "Dinosaur Footprints," a Trustees of Reservations site on Rt 5 in Holyoke right next to the Connecticut River. The site was found while doing construction on the highway.

    As I can tell, it's Eubrontes giganteus, dating to 190 million yrs ago to the late Triassic, early Jurassic.
