doi:10.2204/iodp.proc.339.205.2019 Taxonomic remarksGephyrocapsa species were grouped in several size categories, and the classification followed the morphometric criteria adopted in the “Site U1387” chapter [Expedition 339 Scientists, 2013b]. Specimens <3 µm, mainly Gephyrocapsa ericsonii and Gephyrocapsa aperta, were classified as small Gephyrocapsa. Specimens of Gephyrocapsa muellerae and Gephyrocapsa margerelii and other identified specimens of gephyrocapsids in the 3–5.5 µm size range are referred to as medium Gephyrocapsa group. The large Gephyrocapsa category includes forms >5.5 µm. Gephyrocapsa caribbeanica included midsized specimens (3–5.5 µm) with a closed central area. Reticulofenestra specimens were also considered, following the morphometric criteria adopted in the “Site U1387” chapter [Expedition 339 Scientist (2013b]) and size concepts by Marino (1996) and Marino et al. (2003). Elliptical forms <3 µm were named “small Reticulofenestra,” mainly corresponding to Reticulofenestra minuta. Reticulofenestra haqii and Reticulofenestra minutula were considered “medium Reticulofenestra,” ranging between 3 and 5 µm. Otherwise, taxonomic concepts for Neogene taxa were adopted from Perch-Nielsen (1985) and Bown and Young (1998). Table T2 is a complete list of species identified in samples. |
