The Huayquerian Stage of the South American chronostratigraphic scheme (named for the Huayquerías del Este, Argentina) was originally based on a poorly known mammal association of six taxa from the Huayquerías Formation. We studied the geology, age and fauna of the Neogene sequence in this area, including the Huayquerías, Tunuyán and Bajada Grande formations. The sequence comprises a monotonous succession of synorogenic epiclastic sediments deposited under arid to semi‐arid conditions. Zircon U–Pb dates from 10 tuffaceous levels (7.2–1.6 Ma) place deposition of the Huayquerías Formation during the late Tortonian or Messinian to early Zanclean, the Tunuyán Formation during the Zanclean–Piacenzian, and the Bajada Grande Formation during the Piacenzian–Calabrian. We present 43 and 31 new mammal taxon records for the Huayquerías and Tunuyán formations, respectively. Progressive faunal change was observed along the sequence. The first records of the Chaco tortoise Chelonoidis chilensis and the notoungulate Xotodon major, and the latest records of Interatheriidae and Typotheriopsis (notoungulates), Metacaremys calfucalel, Phtoramys hidalguense and Lagostomus pretrichodactyla (rodents), Chasicotatus ameghinoi and Macroeuphractus morenoi (xenarthrans) are reported. The faunal associations of the Huayquerías and lower Tunuyán formations are highly similar to each other, and to other coeval localities in Argentina. The Macroeuphractus morenoi Assemblage Biozone is proposed as the basis for redefining the Huayquerian Stage, due to the co‐occurrence of three taxa with wide geographical distribution in southern South America: Macroeuphractus morenoi, Pseudotypotherium subinsigne and Lagostomus pretrichodactyla. The age of this biozone is constrained at c. 8–5 Ma in its type area.

“…86 Sr/ 87 Sr dating of mollusks from the underlying Paraná Formation in the locality of Punta Gorda (Diamante, Entre Ríos Province), ranges from 9.47 Ma (Tortonian) (Pérez, 2013b) to 7.55-6.67 Ma (Tortonian-Messinian) (del Río et al, 2018). Considering the relationship between the fauna of the "Conglomerado osífero" and that of other Neogene units (see Cione et al, 2000;Brandoni, 2013;Schmidt et al, 2020), as well as the proposed age for the Paraná Formation (see Pérez, 2013b;del Río et al, 2018), the age of the "Conglomerado osífero" is interpreted as late Miocene.

“…Particularly in the Neogene sedimentary sequence of the Entre Ríos Province, the presence of marine bivalves dominates the fossil record (see Pérez et al, 2013), including a few references to the species Diplodon fraus Ihering, 1907, attributed to strata of the Paraná Formation, as pointed out by Frenguelli (1920: p. 127). Overlaying the mudstone beds of the Paraná Formation, the "Conglomerado osífero" contains a rich fauna of continental vertebrates, mostly mammals (Cione et al, 2000;Brandoni et al, 2019;Schmidt et al, 2020), in association with scarce remains of continental invertebrates (Frenguelli, 1920: p. 83, 85).…”

The freshwater mussels of the family Hyriidae (Bivalvia) are widespread in the Neotropical region, including several fossil and living species of the genus Diplodon Spix. A specimen assigned to Diplodon sp., recovered from the "Conglomerado osífero" (late Miocene) at La Toma Vieja, north of Paraná City (Entre Ríos Province, Argentina), is described herein. The report of Diplodon sp. in the "Conglomerado osífero" would support the traditional interpretation of a fluvial paleoenvironment for this horizon. This is the first accurate fossil record of the genus for the Entre Ríos Province, extending the occurrence of the family Hyriidae to the late Miocene of the Mesopotamian region.

Holocene mammals from Entre Ríos Province, Argentina. We present an unpublished collection of mammals from La Picada Formation (Holocene sensu lato) and San Guillermo Formation (upper Holocene) in the Entre Ríos Province, Argentina, deposited in the collection of the Museo de Ciencias Naturales y Antropológicas “Prof. Antonio Serrano’’ of Paraná City, Entre Ríos. Nine taxa were identified: Dusicyon avus (Carnivora: Canidae), Myocastor coypus (Rodentia: Echimyidae), cf. Hydrochoerus sp. (Rodentia: Caviidae), Dicotyles cf. D. tajacu (Cetartiodactyla: Tayassuidae), cf. Ozotoceros bezoarticus, Mazama sp. (Cetartiodactyla: Cervidae), Bos primigenius taurus (Cetartiodactyla: Bovidae), Equus ferus caballus (Perissodactyla: Equidae) and Cetartiodactyla indet. Ducysion avus and Dicotyles cf. D. tajacu are the first record of these taxa in Entre Ríos. The recognized rodents and cervids are commonly found in archaeological sites and in Quaternary units in Entre Ríos Province. Bos primigenius taurus and Equus ferus caballus are the first findings of post-Hispanic domestic taxa in Holocene sediments from Entre Ríos. The specimen from San Guillermo Formation is the first record of a vertebrate in this unit. Future multidisciplinary studies will be necessary in order to obtain more robust data that will allow us to elucidate the geological and faunistic recent past of the Entre Ríos Province. Keywords: Quaternary, fossils, South America, Argentinian Mesopotamia.
