“…Simone (2006) considered Triplodon Spix in Wagner, 1827 as synonym, unlike Mansur & Pimpão (2008) who described a new species of this genus. The oldest Hyriidae record is from Triassic of New Zealand (Campbell et al 2003) and from Jurassic of South America (Perea et al 2009). Molecular clock indicated a Gondwanan origin of Hyriidae (Graf et al 2015;Santos-Neto et al 2016).…”

Miyahira, I. C.; Santos, S. B.; Mansur, M. C. D. Freshwater mussels from South America: state of the art of Unionida, specially Rhipidodontini. Biota Neotropica. 17(4): e20170341. http://dx.doi.org/10.1590/1676-0611-BN-2017-0341Abstract: Unionida is the most diverse clade of freshwater bivalves. Among the groups occurring in South America, one with the highest number of species is Rhipidodontini (Hyriidae, Unionida, Paleoheterodonta, Bivalvia). However several issues remains on taxonomy and systematic of this group, leading to problems on species identification, description, as also as a limiting factor to other type of studies (e.g., ecology, conservation,…). In this paper is presented a synthesis of available knowledge about Diplodon Spix in Wagner, 1827 and Rhipidodonta Mörch, 1853 in South America, as a first step in order to a better understating of Rhipidodontini. The evaluation of different authors exposes the little agreement between them that resulted in a sort of divergent taxonomical opinions. Some comments on ecology, conservation and habitat preferences were made. This work can also encourage future research on taxonomy, systematic, ecology and conservation of freshwater mussels in South America.

“…Bossi (1966) gave formational rank to these sedimentary deposits, and Bossi et al (1975) further recognized lower and upper members. Perea et al (2009) formalized this nomenclature by naming them Batov ı and Rivera members, respectively. Perea et al (2009) reviewed the paleontologic and chronostratigraphic knowledge of the Tacuaremb o Formation, proposed a Late Jurassic-Early Cretaceous age for it, and identified the Priohybodus arambourgi Assemblage Zone.…”

“…In South America, the Late Jurassic-earliest Cretaceous? Tacuarembó Formation of Uruguay includes a paleoichthyofauna represented by hybodontid sharks (Perea et al, 2001), ceratodontiform dipnoans (Soto and Perea, 2010), a mawsonid coelacanth (Soto et al, 2012) and ginglymodians (Walther, 1932;López-Arbarello et al, 2008;Perea et al, 2009). In contrast, the Almada Fauna includes one species of teleost, †Luisiella feruglioi, the chondrostean †Condorle-pis groeberi, and poorly preserved basal actinopterygians of uncertain relationships.…”

Jurassic freshwater fish faunas are still poorly known, with the only assemblage of that age known from southern South America being the "Almada fauna" of the Cañadón Calcáreo Formation (Oxfordian-Tithonian) of Chubut, Argentina. This fauna is composed mainly by abundant teleosts and a much rarer basal actinopterygian, originally described as †Oligopleurus groeberi and currently usually placed in the genus †Coccolepis. This taxon is here redescribed on the basis of the original specimens and more numerous and better preserved new material from several localities within the Cañadón Calcáreo Formation. The species shows several differences to other coccolepidid taxa, including the apomorphic presence of a sensory canal in the gular plate, and cannot be referred to a known genus. Thus, a new genus name, †Condorlepis gen. nov., is proposed. The detailed anatomical description of †Condorlepis gen. nov. groeberi provides further evidence for the chondrostean affinities of the Coccolepididae and their close relationships with the Acipenseriformes, since this species shows six characters that were hitherto considered to be autapomorphies of the latter clade. A comparison of the Almada fauna with other Gondwanan Jurassic freshwater fish faunas shows close similarities with the roughly contemporaneous fauna of Talbragar, Australia, which also includes an abundant basal teleost and coccolepidids. In contrast, there are marked differences with the faunas of the Early to Middle Jurassic Kota Formation of India, the Late Jurassic to Early Cretaceous Stanleyville beds of the Democratic Republic of the Congo, and the probably Late Jurassic Tacuarembó Formation of Uruguay, in which basal, non-teleostean neopterygians and sarcopterygians are abundant.
