---|---|---|
S. W. Salisbury et al. 2016 | Trackway: weakly heteropodous (30–45%), variably medium- to wide-gauge trackways (sensu Romano et al., 2007 Romano, M., M. A. Whyte, and S. J. Jackson. 2007. Trackway ratio: a new look at trackway gauge in the analysis of quadrupedal dinosaur trackways and its implications for ichnotaxonomy. Ichnos 14:257–270.
[Taylor & Francis Online], [Google Scholar] ), with inner trackway width of 30–50 cm; manual tracks positioned midway between fore and aft pedal tracks, and in line with the rear half of contralateral pedal tracks; manual tracks situated relatively medially, within pedal trackway width. Pedal impressions: large-sized (craniocaudal length: 70–85 cm), near-piriform shape, but broadest across mid-track region, and with a lobed medial margin due to intersection of an asymmetrical heel pad crease; hallucal imprint widened medially by a bulbous cranial pad callosity; external outline of heel region semicircular as a result of occupation by a mediocaudal heel pad callosity; heel pad callosity medially offset and partitioned from fore-heel region of track by well-defined oblique ridge (∼45–75° to the horizontal); acute fore-heel caudal margin of internal track exclusive of heel pad; pedal track angulation between 90° and 100°. Manual impressions: marginally wider than long (∼115%); manual track angulation between 69° and 74°. |
