A new monothalamous foraminiferan from 1000-6300 m water depth in the Weddell Sea: morphological and molecular characterisation
We describe Bathyallogromia weddellensis gen. & sp. nov., a deep-water, monothalamous foraminiferan from bathyal and abyssal sites in the western Weddell Sea. The species is characterised by a delicate, almost spherical, organic-walled test, a low, broad projecting apertural region, and light gr...
