“…Systematic remarks: Despite controversies in usage of Biflustra d’Orbigny, 1852 and Acanthodesia d’Orbigny, 1852 for some Membraniporidae species (Almeida et al, 2017; Cook et al, 2018; Di Martino and Taylor, 2018; Taylor and Tan, 2015), here we follow Almeida et al (2017) and Cook et al (2018) which rejected Acanthodesia as a valid genus of species clearly classified, at least at zooidal morphological level, as Biflustra . The new species is assigned to Biflustra .…”

“…Among the Biflustra species, spinules at basal and vertical walls are known only in Biflustra denticulata (Busk, 1856) and Biflustra paulensis (Almeida et al, 2017; Marcus, 1937). Biflustra denticulata (Figure 8(a)), however, differs in having cryptocystal denticles projecting into the opesia, and in having the proximal cryptocyst narrower than that of Biflustra holocenica sp.…”

“…nov.). The well-known Acanthodesia commensale (Figure 8(b); Klicpera et al, 2013) forming bryoliths, also referred to as Biflustra commensale (Almeida et al, 2017), has large paired gymnocystal tubercles that may be coalescent, and the autozooids are outlined by a brown line, characteristics that are not seen in Biflustra holocenica sp. nov.…”

Palaeoenvironmental dynamics of Holocene shoreface bryoliths from the southern coast of Brazil

et al. 2019

Beds of free-living coated nodules (coralline algae, bryozoans, acervulinid foraminifera) create shallow-water carbonate biogenic benthic habitats, which are sensitive to human disturbance and slow to recover. Holocene bryoliths, ranging from sub-spheroidal, sub-discoidal to sub-ellipsoidal in shape, were found scattered in the foredunes in ca. 30-km stretch along the Hermenegildo and Concheiros do Albardão beaches on the southernmost coast of Brazil (Santa Vitória do Palmar municipality, Rio Grande do Sul State). The dominating bryozoan species forming the bryolith is Biflustra holocenica Vieira, Spotorno-Oliveira and Tâmega sp. nov. The inner bryolith arrangement, generally asymmetrical, shows multilamellar and circumrotatory growth of colonies that envelop the bivalve Ostrea puelchana. Bryozoans and subordinate corals characterize the outer bryolith surfaces. The ichnogenera Gastrochaenolites (made by the boring bivalve Lithophaga patagonica) and Caulostrepsis occur throughout the bryoliths, from the inner part up to the outer surface. The studied bryoliths, originated in a shoreface setting at ca. 7910–7620 cal. yr BP and during subsequent storm waves, were resedimented onto the foreshore and foredunes (to ca. 5700 cal. yr BP) where the bryoliths were finally fossilized.
