To sum up the site in a nutshell, it isn't known for sure if it is Protohadros, as the type specimen is only known from the skull, but it is sure shaping up to be that way, as Protohadros is the only large ornithopod known from this time in Texas.
Protohadros was a large ornithopod native to Texas, living at the very end of the Early Cretaceous period, right before the big extinction in the Turonian that knocked off the stegosaurs, a lot of the pterosaurs, and others.
The supposed stegosaurian track Deltapodus Whyte & Romano, 1994 (Middle Jurassic of England) is sauropod-like, elongate and plantigrade, but many blunt-toed, digitigrade, large ornithopod-like footprints (including pedal print cast associated with the manus of Stegopodus Lockley & Hunt, 1998) from the Upper Jurassic of Utah, better fit the stegosaurian foot pattern.
This developed trail leads the public though a Jurassic-age river channel that has produced a high abundance of dinosaur material, including a partial skeleton of the small ornithopod Othnielosaurus.
Also preserved at the site are the carnivorous dinosaur Ceratosaurus (6 teeth) and the small ornithopod dinosaur Othnielosaurus (one jaw fragment), the latter first identified during the 2008 season.
According to wiki, the Parasaurolophus is a genus of ornithopod dinosaur from the Late Cretaceous Period of what is now North America, about 76-73 million years ago.
Here, a diverse and well-preserved assemblage of dinosaur meat-eating theropod, long-necked sauropod, and plant-eating ornithopod, pterosaur, and bird tracks have been recovered from Lower Cretaceous-aged rocks exposed along the Yellow River.
Several bizarre new dinosaurs have also been recently found in the same geological horizons, including the huge ornithopod Lanzhousaurus magnidens and the gigantic sauropod Huanghetitan liujiaxiaensis.
Here, a diverse and well-preserved assemblage of dinosaur (meat-eating theropod, long-necked sauropod, and plant-eating ornithopod), pterosaur, and bird tracks have been recovered from Lower Cretaceous-aged (about 130 million years ago) rocks exposed along the Yellow River.
