IV.—On some Fossil Entomostraca from South America

Abstract

There are now in the British Museum (Natural History Branch) several specimens of fossil Estheriæ from South America, beside those described and figured in the “Monograph of Fossil Estheriæ” (Palæontographical Society), 1862, pp. 109–111, pi. iv, figs. 8–11.1. There are some from the same locality as those already dealt with, namely, Estheria Forbesii, Jones, from Cacheuta in the province of Mendoza, Argentine Republic.2. Others collected by David Forbes at another place, namely, Arica, Department of Arequipa, in Southern Peru.3. An interesting series from Brazil; partly described and illustrated in the Geological Magazine for May, 1897, pp. 195–202, PI. VIII.

Taxonomy of limnic Ostracoda (Crustacea) from the Alagamar Formation, middle–upper Aptian, Potiguar Basin, northeastern Brazil

“…D ESPITE THE endemism of many limnic lower Cretaceous Ostracoda species, this calcareous microfossil group has been quite important for constructing a useful biostratigraphic framework in the Brazilian marginal basins and in many other basins around the world. After the first taxonomic papers published by T. R. Jones (1860Jones ( , 1897, only Swain (1946) studied the Brazilian Cretaceous limnic ostracodes during the first half of the twentieth century. Since then, many articles addressing the taxonomy of these microfossils in Cretaceous Brazilian paleolakes or paleolagoons have been added: Grekoff (1956), Pinto and Sanguinetti (1958, 1984, Moos (1959), Wicher (1959), Krömmelbein (1961Krömmelbein ( , 1962Krömmelbein ( , 1963Krömmelbein ( , 1964aKrömmelbein ( , 1964bKrömmelbein ( , 1965aKrömmelbein ( , 1965bKrömmelbein ( , 1966Krömmelbein ( , 1967, Grekoff and Krömmelbein (1967), Krömmelbein and Weber (1971), Moura (1972), Bate (1972Bate ( , 1973, Silva (1978aSilva ( , 1978bSilva ( , 1978c, Gobbo-Rodrigues et al (1999a, 1999b, Smith (1999Smith ( , 2000, and Do Carmo et al (2004a, 2004b, 2008.…”

A new crustacean clam shrimp (Spinicaudata: Eosestheriidae) from the Upper Triassic of Argentina and its importance for ‘conchostracan’ taxonomy

“…TRIASSIC spinicaudatans from Argentina have been known since the second half of the 19th century from the descriptions given by Jones (1862Jones ( , 1897 and Geinitz (1876) and the contributions of Phillipi (1887), Kurtz (1921), Rusconi (1948aRusconi ( , 1948b, Camacho (1995) and others. Recently, new studies carried out by the author and coworkers (Gallego 1992, 1999a, 2001a, 2001b, 2005, Gallego & Melchor 2000, Shen et al 2001, Gallego et al 2004) have yielded new records and provided detailed descriptions of Argentinian Triassic spinicaudatan faunas, mainly from the Cuyana and Bermejo basins.…”

The morphology and systematics of the clam shrimp Platyestheria gen. nov. abaetensis (Cardoso) (Crustacea, Spinicaudata) from the Lower Cretaceous of the Sanfranciscana Basin, southeast Brazil

“…The carapaces of Platyestheria abaetensis are, in general, distinct from other species of Cyzicus, which was diagnosed by Jones (1863) by the presence of reticulated ornamentation, occasionally modified with vertical bars, unequal to subequal valves; umbo usually subtriangular to suboval, anterior or occasionally central; the curvature of the valves and growth lines are larger on its posterior portion rather than on the anterior; ventral margin frequently semicircular. However, these diagnostic features are vague and may be applied to distinct genera of clam shrimps, particularly those referred to Eosestherioidea (e.g.…”
