Abbreviations are as follows: AM A. muricatus, CH Ch. kingii, CCa Ct. caudicinctus, CCr Ct. cristatus, CD Ct. decresii, CI Ct. isolepis, CN Ct. nuchalis, CR Ct. reticulatus, DN D. nobbi, DW D. winneckei, GL G. longirostris, IL I. lesueurii, LG L. gilberti, MH M. horridus, PB P. barbata, PV P. vitticeps, RD R. diemensis, TT T. tetraporophora. c shows the inferred phylogenetic tree of relationships between agamids used in this study. All points are coloured according to life habit category. d shows examples of adult skulls that represent extreme variation in shape and different life habits. Scale bar = 10 mm
