''Montanoolithus'' is an oogenus of fossil egg native to Montana. The eggs are about 12 cm long and 6 cm wide, and have a shell 0.7-0.85 mm thick. The holotype eggs were laid in a circular pattern on top of a sandstone mound. ''Montanoolithus'' eggs belonged to some kind of maniraptoran theropod, probably a dromaeosaur.〔D. K. Zelenitsky and F.
