Genus Turinia Traquair, 1896

REMARKS

As there is only one articulated specimen of the type species Turinia pagei , from the Lower Devonian (lower Lochkovian) Lower Garvock Group of Scotland, and rare other patches of scales, we still cannot determine the full extent of variation in this taxon. ħe range of scales apparent on the macrofossils does not “match” the wealth of variation presented by isolated scales in beds of the same age (e.g., Gross 1967; Ørvig 1969a; Turner 1973: figs8a, b, e, g, pl. 2; 1982: pl. 97; Karatajūtė- Talimaa 1978; Märss & Ritchie 1998: fig. 49). ħis is one of the taxonomic problems to be accounted for when examining an assemblage of few scales.

Six of the scales, described below, would seem to be referable to one of the principal genera known in the Devonian, Turinia , by their platform-like crown with rounded undulating ridges or posterior extending lappets.ħe turiniid scales are of different age classes exhibiting from relatively shallow bases to deeper bases with small pulp openings of more mature ones (Märss et al. 2007).
