TL;DR: The stratigraphic continuity of species and line ages, at least for the late Early-early Late Miocene interval, indicates that lakes continuously occupied the system and never were entirely replaced by rivers or the sea.
Abstract: The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachyrotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two families, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be characterised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few species in the Pebas fauna include important ecological groups, such as indicators of marine influence (e.g., Nassariidae, one species), terrestrial settings (e.g., Acavidae, one species) and stagnant to marginally agitated freshwaters (e.g., Planorbidae, four species). Only seven species (4%) representing undisputedly elevated salinities were found, whereas 31 species (20%) are undisputed restricted to freshwater biotopes. Only three (2%) terrestrial gastropod species are known. The Pebas system experienced profuse radiations of molluscs that led to an overwhelmingly endemic fauna, typical of a long-lived lake environment. Several extant genera, which nowadays live outside Amazonia, may have originated within the Pebas system. The stratigraphic continuity of species and line ages, at least for the late Early-early Late Miocene interval (c. 18-9 Ma), indicates that lakes continuously occupied the system and never were entirely replaced by rivers or the sea. The rare occurrence of marine taxa indicates that the system was at sealevel and occasionally experienced marine incursions.

TL;DR: DFs were highest on suspension feeders, parasites and sessile prey, and were lowest on predators, recliners, and endobenthic molluscs, and support paleoecological theory relating predation to changes in ecological guilds through the Phanerozoic.

TL;DR: In this article, the authors compared geographic and temporal patterns at both regional and local scales to decipher the cause of corbulid size trends and found that the increase in nutrient availability and productivity in the Caribbean/western Atlantic as the Central American Isthmus (CAI) emerged.

TL;DR: In this article, a comparison of modern bivalve death assemblages between shallow marine, deep shelf and bathyal settings was performed. Cluster-and discriminant analyses of the bivalves fauna distinguish four sample groups which are primarily separated by water depth (shallow marine vs. deeper shelf vs. bathal) and sedimentological features.

TL;DR: Dominican corbulid species show close morphologic affinities to species of the Pliocene Bowden Formation of Jamaica, Neogenc units of the Caribbean coast of Central America such as the Galun Formation and sediments of the Limon Basin, Miocene and Pl iocene deposits of Trinidad, and Miocene to Pleistocene sediment of Florida.
Abstract: Corbulid bivalves (Myacea: Corbulidac) are an important constituent of fossiIilA:rous Ncogcne sediments of the Cibao Valley, northern Dominican Republic. Six corbulid species referred to live subgenera within the genus Corbula are described and figured {Bothrocorhula, Caryocorbula, Juliacorhula, Panamicorbula, and Varicorbula). One species is new, Corbula {Panamicorbula) canae. This is the first description of a fossil Panamicorbula species and the tirst description of a Panamicorbula species outside ot the eastern Pacific. The distribution of Dominican corbulids is strongly influenced by paleoenvironmental conditions such as salinity, depth, and bioclastic fabric. Corbulids are most common in Miocene sediments that were deposited predominantly in shallow-marine waters. Corbula (Caryocorbula) sericea Dall, 1898 has the widest stratigraphic and geographic distribution within the study area and is especially abundant in brackish-water and very shallow-marine deposits. Corbula (Bothrocorbula) Guppy, 1866b is also common in shallow-marine and l:)rackish-watcr deposits. Corbula (Varicorbula) sanctiilominici Maury, 1925 occurs predominantly in shallow-marine sediments, whereas Corbula {Panamicorbula) canae n. sp. is restricted to brackishwater deposits of the Upper Miocene Cereado Formation in the Rio Cana section. Corbula (Caryocorbula) dominicensis Gabb, 1873b and Corbula (Juliacorbula) fossilis Pilsbry, 1922 are rare. Corbula dominicensis is apparently restricted to the upper Lower to lower Middle Miocene Baitoa Formation of the Rio Yaque del Norte section, and C. fossilis is found in Upper Miocene sediments ol the Cereado and Gurabo Formations. Dominican corbulid species show close morphologic affinities to species of the Pliocene Bowden Formation of Jamaica, Neogenc units of the Caribbean coast of Central America such as the Galun Formation and sediments of the Limon Basin, Miocene and Pliocene deposits of Trinidad, and Miocene to Pleistocene sediments of Florida. vimmea
