Abstract

Macrodon hardingi Dawson, 1868 Original source Dawson (1868): 302, text-fig. 102a–c; originally as “ Hardingi ”. Type stratum and age “bed (e)”, on p. 280 further specified as “Stewiacke limestone [...], Productus Limestone ”; part of the Windsor Group, middle to upper Visean, Mississippian, Carboniferous (Utting 1978). Type locality “ Windsor ”; Nova Scotia, Canada. Type material Dawson had two specimens. Beede (1911) selected the specimen figured on fig. 102a of Dawson (1868) as the “type” (constituting a valid lectotype designation). He separated the other specimen as a new species: dawsoni. Both species are stored together at the Redpath Museum of McGill University, Montreal, Canada, under coll. no. 2820 (coll. Dawson and Hartt). Remarks As Parallelidon [sic] hardingi in Beede (1911: 168, textfig.) and Bell (1929: 156, pl. 26 figs 13–19); as Grammatodon hardingi in Paul (1941: 118); as Grammatodon (Parallelidon) [sic] hartingi [sic] in Calder (1998: 297).
