Abstract
Hadrosaurs were one of the most diverse dinosaur groups in the Late Cretaceous period and are known for their numerous articulated skeletons and monodominant bonebeds (Wosik et al., 2020). They are more commonly known as duck-billed dinosaurs and are found globally including latitudinal extremes such as the artic and Antarctica. Edmontosaurus, a genus of hadrosaur, are herbivores and are very large growing up to 8,000 pounds. Edmontosaurus were known to travel in herds as a defense mechanism and were one of the last non-avian dinosaurs living during the late Campanian stage through the end of the Maastrichtian stage, right up to the K-Pg boundary.
In previous research most Edmontosaurus bonebeds have only held 2-year-old individuals up through maturity. The one-to-two-year individuals seem to be missing in fossil records. The Liscomb bonebed is the only one known to preserve yearling sized individuals. These are presumed to be yearlings based on the size and anatomical structure of the fossils.
