Catalog entries: Globorotalia (Clavatorella) oveyi
Type images:Distinguishing features:
Parent taxon (Globorotaloides): Trochospiral test, ovate to spherical chambers; final chamber often small/bulla-like; cancellate wall.
This taxon: Like G. hexagonus but with curved dorsal sutures and more compresed chambers
Most likely ancestor: Globorotaloides hexagonus - at confidence level 2 (out of 5). Data source: Brummer & Kucera 2022 do not discuss the likely ancestor but given that it is morphologically very close to the long ranging species G. hexagonus it is reasonable to infer this is the most likely ancestor [editor's comment - JRY 2022].
Geological Range:
