Question: what are two differences between the nanotyrannus and tyrannosaurus rex?
Answer: Several features seem to separate it from the Tyrannosaurus genus, including the fact that both Jane and the holotype were found in the same area, near Ekalaka, Montana. Both specimens of Nanotyrannus also have 16 teeth, which is two more teeth sockets present in its upper jaw than in Tyrannosaurus.
