Hadrosaurian dinosaurs were abundant in the Late Cretaceous of North
America, but their habitats remain poorly understood. Cretaceous amber is
also relatively abundant, yet it is seldom found in direct stratigraphic
association with dinosaur remains. Here we describe an unusually large
amber specimen attached to a Prosaurolophus jaw, which reveals details of
the contemporaneous paleoforest and entomofauna. Fourier-transform Infrared
spectroscopy and stable isotope composition (H and C) suggest the amber
formed from resins exuded by cupressaceous conifers occupying a coastal
plain. An aphid within the amber belongs to Cretamyzidae, a Cretaceous
family suggested to bark-feed on conifers. Distinct tooth row impressions
on the amber match the hadrosaur’s alveolar bone ridges, providing some
insight into the taphonomic processes that brought these remains together.
