Fossils of a predatory dinosaur provide novel information about the evolution of
unenlagiines, a poorly known group of dromaeosaurid theropods from Gondwana. The new …

The holotype of the dromaeosaurid Saurornitholestes langstoni was described in 1978 on
the basis of fewer than 30 associated cranial and postcranial bones of a single individual …

The fossil assemblages of the Late Cretaceous of North America are dominated by large-
