Figure 13. Fossil localities on Santa Maria Island, Azores, based on da Veiga Ferreira (1961: fig. 1), Madeira et al. (2011: text-fig. 1) and 
Sibranteta/. (2015: fig. 2). Several other Pleistocene (MIS 5e) localities mapped along south coast by Avila et al. (2015a: fig. 1) are not 
shown. (A) geological map and legend, with fossil localities; (B) semi-diagrammatic east-west cross-section, showing dips on lava flows 
schematically; vertical exaggeration x 20; modified slightly from Sibrant et al. (2015: fig. 6B) to allow Touril Complex to crop out at sea 
level around east coast. (C) location of Santa Maria Island in the Azores (Madeira et al., 2011: text-fig. 1). ■, Pliocene localities with 
Janthina krejcii sp. nov.; •, Pliocene localities, some of which have yielded Janthina typica', O, Pleistocene (MIS 5e) localities (most 
not shown). Focalities: (1) Cre (no Janthina records); (2) Ponta dos Frades (no Janthina records); (3) Pinheiros (probably J. krejcii, 
identification uncertain); (4) Fagoinhas (MIS 5e); (5) Ponta do Norte (locality of Janthina typica neotype); (6) Ponta dos Matos (J. 
typica)', (7) Ponta das Salinas (J. typica)', (8) Ponta do Castelo (J. typica', includes also late Pleistocene, MIS 5e); (9) Pedra-que-pica (no
