Fig. 1 in An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada

Fig. 1. Overview of the systematically searched "section D" above the Paleozoic–Mesozoic contact on top of the northwestern edge of "T−cirque" near "Fossil Fish Lake" in the Wapiti Lake Provincial Park (see Neuman and Mutter 2005 for details of locality) showing position of the three major fish assemblages. Tentative identifications of the time−sensitive fossils and respective presumed stages left in figure. Summarized occurrence of the major faunal elements right in figure. The denticles occur in very large numbers in the mid−section (denticle symbols). Below and above that part of the section, however, the denticles are found much less frequently.
