“…Melitasphaeridium choanophorum was originally described from post-Upper Miocene sediments of Australia (Deflandre and Cookson, 1955) and has since been recorded in the Northern Hemisphere from the Oligocene of Germany (Benedek, 1972), the Lower Miocene and Pliocene of offshore eastern Canada (Williams, 1975;Williams and Bujak, 1977) and the Lower to Middle Miocene of the offshore Norwegian-Greenland Sea (Manum, 1976). Late Quaternary records are restricted to the Cariaco Basin (Mertens et al, 2009;Bringué et al, 2019), the Gulf of Mexico (Limoges et al, 2014) and the South China Sea (Li et al, 2017). Melitasphaeridium choanophorum has been observed in modern sediment from the Gulf of Mexico (Limoges et al, 2013;Price et al, 2017).…”
