![]() Photo by Christopher Michel ![]() Since adult Edmontosaurus body fossils have been found on Alaska’s North Slope and the foot characteristics and rock ages are very similar, both the adult and juvenile hadrosaur prints in Denali are attributed to the same genus. ![]() Photo by Tony Fiorillo Edmontosaur chicks were probably fed by their parents until they could safely leave the nest. It is difficult to know what the chicks ate, but it may have been plants, regurgitated plants, a milk-like substance similar to what pigeons produce in their throats, or a combination of these. How do we know I lived in Denali? Numerous footprints of juvenile Edmontosaurus have been found in Denali in close proximity to adults walking in the same direction at the same time. This is excellent evidence that Edmontosaurus bred and raised young in Denali. ![]() Fossils trackways featuring adult and juvenile Edmontosaurus walking side-by-side have been found in Denali, reinforcing the well-established idea that hadrosaurs actively cared for their young. |
