FIGURE 10 in Depth related brachiopod faunas from the lower Cambrian Forteau Formation of southern Labrador and western Newfoundland, Canada

FIGURE 10. Distribution of brachiopod taxa recovered from sections measured in the Forteau Formation of the south Labrador coast. Shaded area indicates known stratigraphic range of individual taxa. Correlation of adjacent sections is approximate only. For more exact correlation of sections and samples see Figure 3.

Fig. 7 in An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada

Fig. 7. Histology of dermal denticles of Listracanthus pectenatus sp. nov., Lower Triassic, Wapiti Lake, British Columbia. A. Horizontal cross−section (perpendicular to long axis) of specimen UALVP 1889 (section T1). Note the secondarily "remodelled" central areas between the lateral ridges. B. Vertical sections along plane and long axis of a large denticle of specimen UALVP 38562 (sections T1 and T2). Note the large, well−defined cavities in the bases of the denticles in B1, B2 and the solid processes of the posterior border in B3. B4, B5. Vertical cross−sections (as above) of specimen UALVP 38562 (section T4 [B4] and section T6 [B5]) show that the bases of the comb−like processes in the posterior border are only in part secondarily ossified, complex structures with small lateral processes. All arrows point posteriad.

As preserved in specimen TMP 95.114.52. B. Aberrant denticle as preserved in specimen TMP 2001.18.01. B1. General view. B2. Close−up of the mid−portion.

Fig. 4 in An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada

Fig. 4. Listracanthus pectenatus sp. nov., Lower Triassic, Wapiti Lake, British Columbia. Specimen UALVP 46551 showing morphological details of a large denticle (type I). A. A complete large denticle. Large denticles may vary in length, width and curvature. B. The apex of a large denticle with the fulcral ridges arranged like a "tuft". C. The posterior border as preserved in the same specimen. Note that each straight process possesses a striated shaft (1) and a triangular base (2) lateral to the process (see also thin sections in Fig. 7). D. Detail of postero−basal corner of the posterior border.

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.

Fig. 8. A. A large denticle of Listracanthus hystrix, Upper Carboniferous, Bethel Quarry, Pike County, Indiana, USA. (A1), specimen BMNH P. 62273, with close−ups of the apical tip (A2) and base (A3) of denticles on the same slab. B, C. Small denticles (equivalent "type II" in L. pectenatus sp. nov.) of Listracanthus wardi, Upper Carboniferous, Smallthorne, North Staffs, UK, (associated with large denticles, [equivalent "type I", not shown), specimens BMNH 10005 (B) and BMNH 10004 (C).

Fig. 9 in An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada

Fig. 9. An artist's view of a possible life restoration of the chondrichthyan Listracanthus with the large type I−denticles restored along the dorsal ridge (Art− work © Ray Troll, 2001).

Fig. 6 in An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada

Fig. 6. Associated fragment (A) and sketch (B) of a?tooth−like fragment or skeletal fragment preserved on a slab with both types of denticles (not shown) of Listracanthus pectenatus sp. nov., Lower Triassic, Wapiti Lake, British Columbia, in specimen UALVP 38562.

Fig. 2 in An enigmatic chondrichthyan with Paleozoic affinities from the Lower Triassic of western Canada

Fig. 2. Small and large dermal denticles in holotype specimen UALVP 47002, a possible body part of Listracanthus pectenatus sp. nov., Lower Triassic, Wapiti Lake, British Columbia. A. A large number of denticles is irregularly arranged but an unusually high number is clustered to the left. On the right, denticle types I and II are widely spaced, clearly unrelated to each other. B. Three large denticles (type I) as preserved (close−up). C. Small denticles (type II) as preserved, showing variable crown shape (close−up).
