Dale Russell
The name Deinodontidae was coined by Edward Drinker Cope in 1866 for this family, and continued to be used in place of the newer name Tyrannosauridae through the 1960s. The type genus of the Deinodontidae is "Deinodon", which was named after isolated teeth from Montana. However, in a 1970 review of North American tyrannosaurs, Dale Russell concluded that "Deinodon" was not a valid taxon, and used the name Tyrannosauridae in place of Deinodontidae, stating that this was in accordance with ICZN rules. Therefore, Tyrannosauridae is preferred by modern experts.
