Nesov described the new species Troodon asiamericanus. [6] Troodon eggs continued to attract scholarly attention in the 1990s. 1996. Darla Zelenitsky and Leonard Hills described the eggs of Troodon formosus. They found that the surface of Troodon eggs were smooth and their pores occurred singly or in pairs.
