Phylogenetic relations
Most likely ancestor: Globoturborotalita druryi - at confidence level 3 (out of 5). Data source: Kennett & Srinivasan 1983, Hayashi et al. 2013 - however Aze et al. (2011) remove G. druryi from Globotuborotalita and derive G. nepenthes directly from G. woodi. .
Geological Range:
Last occurrence (top): at top of PL1 [Atl.] zone (100% up, 4.4Ma, in Zanclean stage). Data source: Wade et al. (2011), zonal marker
First occurrence (base): at base of M11 zone (0% up, 11.6Ma, in Tortonian stage). Data source: Wade et al. (2011), zonal marker
