Title: | An Unusual, Three-Dimensionally Preserved, Large Hadrosauriform Pes Track from "Mid"-Cretaceous Jiaguan Formation of Chongqing, China | Contributor(s): | Xing, Lida (author); Bell, Phil (author) ; Harris, Jerald D (author); Currie, Philip J (author) | Publication Date: | 2012 | DOI: | 10.1111/j.1755-6724.2012.00660.x | Handle Link: | https://hdl.handle.net/1959.11/14793 | Abstract: | Three-dimensional tracks provide unique insights into the locomotor mechanics of their track makers. An isolated, large hadrosauriform print attributable to 'Caririchnium lotus' from the "mid"-Cretaceous Lotus track site (Jiaguan Formation) in China permits reconstruction of the footfall, weight-bearing, and kick-off phases of the step cycle. Large-scale modifications of the pes during the step cycle indicate 'C. lotus' trackmakers were capable of locomotory modifications in response to substrate consistency beyond the "expected" shift between bipedal and quadrupedal postures. An unusual curvature to the trace of one of the outer digits indicates substantial transverse mobility. The remaining digits demonstrate lesser degrees of transverse movement accompanied by extension of the digits during footfall. The absence of overprinted scale-scratch marks and toe drags are consistent with a vertical kick-off of the pes and concomitant flexion of the digits. This track suggests that pedal mobility in 'C. lotus' track makers was greater than previously suspected and has implications for reconstructions of hadrosauriform locomotion. | Publication Type: | Journal Article | Source of Publication: | Acta Geologica Sinica (English Edition), 86(2), p. 304-312 | Publisher: | Wiley-Blackwell Publishing Asia | Place of Publication: | Australia | ISSN: | 1755-6724 1000-9515 |
