“…It would be necessary to recover more and better-preserved specimens in order to make a precise identification, but it is possible to affirm that the morphotype 1 resembles Textularia gramen d'Orbigny 1846, while the morphotype 2 is similar to Textularia candeina d'Orbigny 1939. Both these species are common in Recent deposits of South Atlantic inner shelves (e.g., Boltovskoy et al 1980;Vieira et al 2014) and correspond to tropical or subtropical taxa (e.g., Montaggioni and Vénec-Peyré 1993;Eichler et al 2012).…”

Here are reported the first certainly indigenous agglutinated foraminifera known for the Eocene La Meseta Formation on Seymour Island, West Antarctica. The specimens were identified as Textularia sp. and occur in the upper portion of the unit, just below the contact with the overlying post-Eocene deposits. Despite being rare, the specimens are interpreted as autochthonous or parautochthonous due to their overall good preservation, fragility, and lack of sedimentary filling. The La Meseta Formation seems to have passed through a major diagenetic dissolution of calcareous microfossils, but the present findings suggest that indigenous agglutinated foraminifera can be found at least in some of its strata.
