“…It differs from Tanycythere praecaudata Cabral and Loureiro in Cabral et al ., from the Jurassic of the Portugal in having a less inflated carapace, absence of a keel posteroventrally and in being less rounded.…”

A total of 113 species belonging to 54 genera are recovered from a study of the Maastrichtian and Danian deposits in the Cerro Azul section of the Neuquén Basin, west‐central Argentina. Of these, 9 new genera, 38 new species and 28 species in open nomenclature are recorded. These form the basis of the present study and are listed below. Genera: Phelocyprideis gen. nov., Aleisocythereis gen. nov., Apatoleberis gen. nov., Mimicocythereis gen. nov., Castillocythereis gen. nov., Hysterocythereis gen. nov., Orthrocosta gen. nov., Petalocythereis gen. nov. and Sthenarocythereis gen. nov. Species: Cytherella saraballentae sp. nov., Cytherella semicatillus sp. nov., Paracypris bertelsae sp. nov., Paracypris imaguncula sp. nov., Argilloecia abnormalis sp. nov., Argilloecia concludus sp. nov., Argilloecia hydrodynamicus sp. nov., Bythoceratina cheleutos sp. nov., Phelocyprideis acardomesido sp. nov., Eucythere dinetos sp. nov., Krithe crepidus sp. nov., Cytheropteron hyperdictyon sp. nov., Cytheropteron bidentinos sp. nov., Cytheropteron translimitares sp. nov., Aversovalva glochinos sp. nov., Eucytherura stibaros sp. nov., Hemingwayella verrucosus sp. nov., Heinia prostratopleuricos sp. nov., Loxoconcha (s.l.) posterocosta sp. nov., Keijia circulodictyon sp. nov., Keijia kratistos sp. nov., Paramunseyella epaphroditus sp. nov., Munseyella costaevermiculatus sp. nov., Ameghinocythere archaios sp. nov., Aleisocythereis polikothonus sp. nov., Castillocythereis multicastrum sp. nov., Castillocythereis albertoriccardii sp. nov., Cythereis stratios sp. nov., Cythereis clibanarius sp. nov., Cythereis trajectiones sp. nov., Henryhowella (Wichmannella) praealtus sp. nov., Hysterocythereis paredros sp. nov., Hysterocythereis coinotes sp. nov., Hysterocythereis diversotuberculatus sp. nov., Orthrocosta decores sp. nov., Orthrocosta atopos sp. nov., Orthrocosta phantasia sp. nov. and Sthenarocythereis erymnos sp. nov. The nature of the fauna and aspects of its evolution are discussed.

“…Remarks. The disjunct stratigraphical and geographical record of Tanycythere reported by Cabral et al (2014) is supplemented by the species below, and also by the recognition that Cytherura striatoides Bonnema, 1941 from the Upper Cretaceous of The Netherlands (Bonnema 1941), Baltic coast of Germany (Herrig 1966) and England (Weaver 1982) may also belong to Tanycythere.…”

Late Callovian (athleta Chronozone) age sediments of Pedrógão, west coast Portugal, yielded a low diversity ostracod assemblage with relatively little in common with coeval NW European assemblages except at the weak level of comparative (cf.) species identification. Five new marine species are described (Neurocythere multiforma sp. nov., Palaeocytheridea (Malzevia)? dorsocostata sp. nov., Praebythoceratina parascrobiculata sp. nov., Praeschuleridea lisensis sp. nov., Virgulacytheridea posteroacuminata sp. nov.) and three previously described non-marine species recorded that so far are indigenous to Portugal (Septacandona azeredae, Sinuocythere pedrogaensis, Theriosynoecum helmdachi). Ostracod taxonomic links to western Tethys are evident but weak. Calcareous nannofossil assemblages were analysed for biostratigraphical control.

“…The Lusitanian Basin of central western Portugal is an important Mesozoic depocentre, and the calcareous microfossil biostratigraphy of the Lower Jurassic succession has been well studied recently (e.g., Perilli and Duarte, 2006;Oliveira et al, 2007a;Pinto, 2008;Reggiani et al, 2010;Henriques and Canales, 2013;Mattioli et al, 2013;Cabral et al, 2014Cabral et al, , 2015Henriques et al, 2014;Ferreira et al, 2015;Rita et al, 2016). By contrast, the Jurassic palynology of this significant sedimentary basin has received relatively little attention.…”

A comprehensive investigation of the Early Jurassic stratigraphical palynology of the Lusitanian Basin in western Portugal was undertaken, with most emphasis placed on dinoflagellate cysts. A total of 214 samples, from an upper Sinemurian to upper Toarcian composite section based on six successions, were examined. The Sinemurian material examined was barren of dinoflagellate cysts, however the Pliensbachian and Toarcian successions are characterised by relatively low diversities. Luehndea spinosa, Mancodinium semitabulatum, Mendicodinium microscabratum, Nannoceratopsis gracilis, Nannoceratopsis senex and Scriniocassis priscus were relatively common, and are biostratigraphically significant. Luehndea spinosa dominates the lowermost 2 Toarcian (Dactylioceras polymorphum ammonite Biozone), and is an index species. At the base of Hildaites levisoni ammonite Biozone, the effects of the Toarcian-Oceanic Anoxic Event (T-OAE) caused Luehndea spinosa to become extinct. At the same time, dinoflagellate cyst abundance and diversity markedly decreased. After the T-OAE, during the middle and late Toarcian, phytoplankton recovery was prolonged and slow in the Lusitanian Basin. The Luehndea spinosa and Mendicodinium microscabratum dinoflagellate cyst biozones were defined, both of which are subdivided into two dinoflagellate cyst subbiozones.
