== Brontosaurus attack ==
[[File:Allosaurus_Brontosaurus.png|thumb]] Allosaurus made one more appearance in a Sunday strip as a minor alter ego of Calvin's. In it, the ''Allosaurus'' ambushed a herd of ''Apatosaurus'' (identified as ''Brontosaurus'') and jumped on a straggling member of the group. The Allosaurus was conscious of the danger of attacking such a large animal, but did so anyway due to desperation in hunger. Allosaurus was here analogous to Calvin jumping on his father while he was cooking, exclaiming that he was hungry.
