The Hell Creek lambeosaur is a possible genus of lambeosaur that lived in North America during the Late Cretaceous.
Description[]
This genus is known from limb bones and fragmentary scraps, which may represent a known genus of lambeosaur from the Hell Creek Formation. Old faunal lists list Parasaurolophus in Hell Creek, but no reviews have elaborated or even mentioned this. The known material from limbs is elongate, with morphology that may distinguish it from Edmontosaurus but is also similar to Lambeosaurus. This taxon was once thought to be a saurolophine, but this was disproven by Brownstein and Bissell (2020). However, the material could also be misidentified, with further research needed to confirm or deny the lambeosaurine allegations.
