Bellatoripes (Latin for "warlike foot") is an ichnogenus of footprint produced by a large theropod dinosaur so far known only from the Late Cretaceous of Alberta and British Columbia in Canada.
Such inferences of behaviour cannot be made with fossil bones alone, so the record of Bellatoripes tracks together is important for understanding how large predatory theropods such as tyrannosaurids may have lived.
Bellatoripes and other tyrannosauripodid tracks cannot be definitively assigned to Tyrannosauridae based on shared morphological traits alone, but the absence of other large theropods from the same geographical areas and stratigraphic ages precludes any other identities for the trackmakers.
[1] The presence of three, parallel Bellatoripes trackways inferred to have been created in a short span of time is suggested to indicate that tyrannosaurids were social, gregarious animals that travelled in groups.
Similarly, the age of the track-makers could be inferred from the dimensions of the footprints compared to the estimated hip height based upon contemporary tyrannosaurids that likely produced Bellatoripes tracks (Albertosaurus, Gorgosaurus, and Daspletosaurus).
[1] The fine preservation of the distal digits and small, parallel striations (interpreted as drag marks) within Bellatoripes tracks suggests that the track-makers partially withdrew their feet backwards before stepping forward, leaving the overlying sediment undisturbed.
This contrasts with what is typically seen in other theropod footprints, where the tips of the digits drag as they are pulled forward, but is similar to the observed movements of ostrich feet during locomotion.
