This file includes a previously-unpublished pathology survey of pedal phalanges from tyrannosaurid dinosaurs cataloged at the Royal Ontario Museum (Toronto, Ontario, Canada). The Excel spreadsheet includes columns for specimen number, taxon, locality, identity of element, pathology, and element description. Because these specimens are from historic collections, locality data are imprecise. All elements were isolated, and thus cannot be assigned more precisely than "Tyrannosauridae." Data were collected in August 2006, by Andrew Farke.
