Figure 8 in Before the freeze: otoliths from the Eocene of Seymour Island, Antarctica, reveal dominance of gadiform fishes (Teleostei)
Figure 8. Eocene palaeogeography in south polar projection and the distributions of selected taxa of Protacanthopterygii, Paracanthopterygii and Berycoidei. Regions studied for fossil otoliths are marked by an asterisk (each region may contain multiple locations). Otolith data are compiled from Schwarzhans (1980, 1985); the palaeogeographical reconstruction is based on Reguero et al. (2013); the delimitation of the Weddellian bioprovince is based on Zinsmeister (1982); the reconstruction of palaeocurrents is composed from Crame (1999) and Huber et al. (2004).
