Scientists have identified the fossilised remains of a tiny marsupial (Unnuakomys hutchisoni) that lived in Alaska during the Late Cretaceous.
The maxilla of a dog-sized dinosaur, a member of the Leptoceratopsidae from North America has been identified in the fossil collection of the Peabody Museum.
Bones from an Alvarezsaurid dinosaur were discovered in Uzbekistan and could shed light on the evolution and origin of the species, according to a study published October 25, 2017 in the open-access journal PLOS ONE by Alexander Averianov of Zoological Institute of the Russian Academy of Sciences, Russia and Hans-Dieter Sues of the Smithsonian Institution, USA.

Bank Holiday. Late Cretaceous. | Military dioramas and vignettes telling their own story.
The Late Cretaceous (∼95–66 million years ago) western North American landmass of Laramidia displayed heightened non-marine vertebrate diversity and intracontinental regionalism relative to other latest Cretaceous Laurasian ecosystems. Processes generating these patterns during this interval remain poorly understood despite their presumed role in the diversification of many clades. Tyrannosauridae, a clade of large-bodied theropod dinosaurs restricted to the Late Cretaceous of Laramidia and Asia, represents an ideal group for investigating Laramidian patterns of evolution. We use new tyrannosaurid discoveries from Utah—including a new taxon which represents the geologically oldest member of the clade—to investigate the evolution and biogeography of Tyrannosauridae. These data suggest a Laramidian origin for Tyrannosauridae, and implicate sea-level related controls in the isolation, diversification, and dispersal of this and many other Late Cretaceous vertebrate clades.
Animal gives us a better picture of life’s diversity over 66 million years ago.
A giant, ostrich-like dinosaur and its smaller cousin, also an ornithomimosaur, sprinted through what is now Mississippi about 85 million years ago.
