“…The species Pelecocythere carinoalatum (Bate, 1972), recovered here from the Danian interval, had been previously described from the Campanian of the Carnavon Basin, western Australia (Bate 1972), James Ross Island, Antarctic (Fauth et al 2003) genus from the Neuqu en Basin.

It is likely that this species had its origins in Australia and migrated to the Antarctic and Argentina during the Late Cretaceous following bottom oceanic currents (Dingle 2009), reaching the Neuquén Basin through the marine transgression that occurred into Argentina during this period.…”

This work presents a taxonomic, palaeoecological and palaeobiogeographical study of the ostracod fauna around the Cretaceous–Palaeogene boundary from the El Matuasto section, Neuquén Basin, Argentina. The analysis of 64 samples resulted in the recovery of 82 marine ostracod species, of which four are new: Hemiparacytheridea condilomata, Paramunseyella stictus, Hysterocythereis acuminata and Aleisocythereis? picnus. In addition, the genera Sapucariella, Monoceratina, Aracajuia, Microceratina and Pelecocythere are reported for the first time from the Neuquén Basin. Palaeoecological inferences indicate fluctuations in abundance and diversity, occurring alongside environmental change from an inner to medium shelf during the Maastrichtian and to an outer shelf in the Danian. The Maastrichtian fauna was less abundant than that in the Danian, which shows a rapid recovery after the Cretaceous–Palaeogene boundary. During the Danian, a small interval also shows a sudden decrease in abundance and diversity that could potentially be related to the Dan‐C2 event. In addition, the described genera and species in this study suggest a strong palaeobiogeographical affinity with the Paraíba Basin, northeastern Brazil.

“…No extant ostracode species has been reported from the Cretaceous of the region (Fauth et al 2003) and the oldest extant ostracode record in the Antarctic region is Kuiperiana meridionalis , which is almost identical to the species reported from the Eocene of Seymour Island, Antarctic Peninsula . This species is also reported from the Oligocene of southernmost South America as Palmoconcha?…”

Modern benthic ostracodes from Lutzow-Holm Bay, East Antarctica: paleoceanographic, paleobiogeographic, and evolutionary significance

Seventy-three ostracode species from 38 genera were recovered from the 55 surface sediment samples in Lützow-Holm Bay, northeastern Antarctica. We investigated bathymetric and geographic distributions of modern benthic ostracode species in the bay and compared this fauna with published modern and fossil ostracode data of Antarctic and southern South American regions. The results show: (1) Four biotopes and three sub-biotopes are recognized based on Q-mode cluster analysis, which suggest distributions of modern ostracodes are mainly controlled by water-mass structure, ice scouring, and light availability. (2) Comparison between the Lützow-Holm Bay fauna and other ostracode faunas from Antarctica and southern South America shows high endemism and homogeneity of Antarctic ostracode fauna, suggesting in situ evolution of most extant Antarctic species. (3) Most species are endemic to the Antarctica, a few species also inhabit South American waters.

“…The species Cytherelloidea spirocostata, which occurs in the Upper Maastrichtian in the basin, has been recorded for the Danian of Argentina (Bertels 1973) and the Campanian of Antarctica (Fauth et al 2003). Cytherelloidea is considered to be a thermophilic genus in shallow seas (minimum 10°C ), where it is less tolerant than Cytherella to environmental change (Sohn 1962).…”

A total of 479 samples from five drill-holes of the Pelotas Basin were analysed. Despite the huge number of samples, only 98 specimens were recovered, belonging to nine families, 21 genera and 34 species (most in open nomenclature). Due to the paucity and poor preservation of this material, just seven taxa were identified or tentatively identified at the species level: Cytherella cf. C. araucana Bertels, Cytherelloidea spirocostata Bertels, Bairdoppilata triangulata Edwards, Actinocythereis indigena Bertels, Brachycythere gr. sapucariensis Krömmelbein, Wichmannella araucana Bertels and Wichmannella meridionalis Bertels. Four taxa could not even be identified at the generic level and are referred as "gen. et sp. indet.". Trachyleberididae and Cytherellidae were the most diversified and abundant families while Cytherella and Paracypris were the most diversified genera, with seven and four species, respectively. The K-Pg boundary in the Pelotas Basin is marked by a faunal change with the local disappearance of the genera Cytherelloidea, Argilloecia, Cythereis, Brachycythere, Pondoina and Rostrocytheridea, and the first local occurrence of Neonesidea?, Bairdoppilata, Ambocythere, Buntonia, Langiella?, Trachyleberis and Krithe. The genera Cytherella, Paracypris, Wichmannella and Actinocythereis are recorded in the Cretaceous as well as the Paleogene. This faunal study suggests a neritic marine environment for the analysed interval.
