Figure 6. Bivariate graph plotting the footprint length/footprint width ratio against the mesaxony (AT) of the studied tracks (gracile and robust morphotype) with the larger tracks described in the Reuchenette Formation.

(A) Gracile and robust morphotype compared with Megalosauripus tracks (including tracks classified as Megalosauripus transjuranicus, Megalosauripus cf. transjuranicus and Megalosauripus isp.), the Morphotype II tracks and Jurabrontes curtedulensis (after Razzolini et al., 2017; Marty et al., 2017). Note that in many cases the points represent tracks from the same trackway, so variation through the trackway is also represented. (B) The studied tracks compared with just the holotype and paratype specimens of Megalosauripus transjuranicus and Jurabrontes curtedulensis, plus the best-preserved tracks of Morphotype II (BEB500-TR7). Outline drawings not to scale. The specimen in red is CRO500-T10-L10 (previously classified as Carmelopodus and herein consider as part of the gracile morphotype, see discussion).
