Fig. 11 in Givetian (Middle Devonian) sharks from Cairo, New York (USA): Evidence of early cosmopolitanism

Fig. 11. Early Devonian (400 Ma) map in South Polar Mollweide projection with occurrence of remains currently assigned to the Antarctilamnidae and Portalodus. Locality numbers for the Antarctilamnidae refer to Table 1; when more than one locality are represented by the same symbol, the oldest one is depicted. Portalodus was reported in Antarctica (Young 1982; Long and Young 1995; localities 1.1–1.3 in Antarctilamnidae), South Africa (Anderson et al. 1999; locality 9 in Antarctilamnidae), and New York (this paper; locality 14 in Antarctilamnidae). Map modified from Blakey (2008: fig. 8B).
