Geological Range:
Notes: Globigerinoides joli ranges from Subzone M1b to Zone M4? Spezzaferri (1994). Additional studies are needed to confirm the presence of this species in younger Miocene sediments. [Spezzaferri et al. 2018]
Last occurrence (top): within M4 zone (16.38-17.54Ma, top in Burdigalian stage). Data source: Spezzaferri et al. 2018
First occurrence (base): within M1b subzone (21.12-22.44Ma, base in Aquitanian stage). Data source: Spezzaferri et al. 2018
