Hadrosaurid migration: Inferences based on stable isotope comparisons among Late Cretaceous dinosaur localities.
If the hadrosaurids were overwintering on this Arctic insular landmass, they would have had to subsist on local food sources.
Although caribou are sometimes invoked as modern analogues of Arctic hadrosaurids (e.
In addition to conifer needles and seeds, hadrosaurids living in this area may have consumed a larger proportion of woody plant organs during the winter.
They are undoubtedly not the juvenile forms of the larger hadrosaurid taxa described in other localities of the region (Cruzado-Caballero, 2012) and will represent a new undescribed hadrosaurid taxon of diminutive size.
