In Depth Stegouros is a genus of small ankylosaurian dinosaur that lived in South America during the late Cretaceous. What is an immediate stand out feature of this dinosaur is the tail which has a very distinct arrangement of osteoderms.

Issi was established as the new published name of the genus … Read more
In Depth Protopteryx is a genus of enantiornithine bird that lived in Asia during the early Cretaceous.

In Depth Neuquensaurus is easily one of the smallest of the known titanosaurs, with only genera such as Magyarosaurus being known to clearly be smaller. Neuquensaurus has had a fairly complicated taxonomic history with fossils of Neuquensaurus previously being described as belonging to both Titanosaurus and Saltasaurus before being renamed as Neuquensaurus. In addition to … Read more
