Introduction
The line of research developed and consolidated so far, is about paleodiversity and paleoecology of continental mollusks of the fossil record of Uruguay. The main objectives are, the taxonomic description of the fauna of fossil mollusks present in the different lithostratigraphic units of the continental record on the one hand, and on the other hand, reconstruct the paleoenvironment of these units from the ecological characteristics of the different mollusk taxa. Within the framework of this line of research, four new fossil species were described, as well as several publications in international scientific journals.

In the Late Cretaceous fossil record of Uruguay, three morphotypes of Bulimulus (Bulimulidae) have been recorded: Bulimulus klappenbachi and two undescribed ones. A geometric morphometric analysis was conducted to show whether the three morphotypes represent one or more species. With this aim, the three fossils were compared with three extant speci...
Highlighting the latest research on Actualistic Taphonomy (AT), this book presents the outcomes of a meeting that took place in Montevideo, Uruguay, in October 2017. Its respective chapters offer valuable insights into South American archaeology, invertebrate and vertebrate fauna, and flora.
In recent years, there has been a surge of new research o...
The South American fossil record of pulmonate gastropods counts with circa 100species from the Cretaceous to the Pliocene. As this knowledge is largely scattered in the literature, we present here a checklist of these fossils, with relevant data about each species’ type locality, stratum and age, and illustrating the type specimens whenever possibl...
Paleoecological studies of continental gastropods give valuable information about the depositional environment of the fossil assemblages. In South America, these assemblages from the Late Cretaceous/Paleocene are scarce and poorly studied. Most works focuses on taxonomy, but a paleoecological approach is still missing. We analyzed the assemblages p...
Only a few studies on Quaternary continental mollusks of Uruguay have been published over the last few decades. Despite the high occurrence of this group in many of the Late Pleistocene outcrops of the country, all of them are better known for their classic Ice Age mammal assemblages. To overcome this situation, 23 localities were sampled from two...
The morphology of otoliths determines the function they perform, and it is influenced by genetic and environmental factors. Knowing those relationships is necessary to understand the role of hearing in fish. The objectives of this work were: exploring the shape of the sulcus of the sagittal otolith in seven species of Sciaenidae, in relation to sou...
NOTA RESUMEN La tafonomía actualista permite conocer las condiciones ambientales que influyen en la preservación de restos biológicos, e inferir las condiciones de acumulación de restos fósiles. Se explora el uso del gasterópodo invasor Rapana venosa (Valenciennes, 1846) en el Río de la Plata como modelo de tafonomía actualista, utilizando sus rasg...
En Uruguay el Cuaternario está representado por varias unidades continentales que se encuentran tanto en el norte como en el sur del territorio; esta tesis se centra en dos de ellas, las Formaciones Sopas y Dolores. Las mismas fueron seleccionadas debido a que ambas tienen un contenido considerable de fósiles de moluscos, tanto en cantidad como en...
Adequate values of environmental parameters are crucial for the long-term preservation of the fossils in a palaeontological collection. In particular, incorrect or fluctuating temperature (T) and relative humidity (RH) can affect glued or repaired materials, induce the proliferation of mould, provoke mechanical breakage, recrystallization or minera...
The use of alien invasive species is applied for the first time to evaluate the taphonomic damage during a period of up to two decades, in natural conditions. A preliminary study using shells of the gastropod Rapana venosa collected in a microtidal beach showed that the specimens suffered important damage in the considered time span, comparable wit...
In the last 40 years, successive revisions have been introduced to the lithostratigraphy of the Late Cretaceous of the Norte Basin, whose record is formed by predominantly siliciclastic continental fossiliferous sedimentary rocks. A factor that contributed to the terminology proliferation was the misplaced importance attributed to the epigenetic pr...
A new fossil species of Biomphalaria Preston is described for the Upper Cretaceous of Uruguay (Queguay Formation). The new species is characterized by a conspicuous spiral ornamentation, a unique character within the genus. This new Biomphalaria species is the third known for the Queguay Formation, in addition to B. walteri (Parodiz) and B. reversa...
A new species of Pupoides Pfeiffer 1854, subgenus Ischnopupoides Pilsbry 1926, is described for the Late Cretaceous of Uruguay (Queguay Formation), being the oldest record of the genus and subgenus. Pupoides (I.) gnocco new species is characterized by a small dextral fusiform shell, constituted by a spire comprising five slightly convex whorls, obl...
The freshwater genus Biomphalaria Preston, 1910 is a well studied genus of freshwater snails, due to its importance as an intermediate host of the human parasite Schistosoma mansoni (Platyhelminthes). Soft parts are used to differentiate among modern species of Biomphalaria, but these parts are not present in fossils. The aim of this paper is to sh...
The lithostratigraphic unit "Calizas del Queguay" (Queguay limestones) crop out in the Uruguayan sector of the Paraná Basin and in the Santa Lucia Basin, and marginally in the Argentinean littoral of the Uruguay river. The outcrops are distributed along an important part of the Uruguayan territory, and they are especially important in the Queguay a...
The origin and paleoenviroment of the Queguay Formation have been and are
still being discussed. This formation outcrops in the Uruguay river littoral (Soriano, Río Negro, Paysandú and Flores departments) and in the south of the country (Canelones department). The fossil association of the littoral differs from that in the south, and they were name...
The land snail family Odontostomidae has a poor fossil record, mainly from the middle Paleogene and early Neogene of Argentina. In this paper a new species of Odontostomidae from the Paleocene of Uruguay (Queguay Formation) is described. Bahiensis priscus n. sp. represents the first record of the genus Bahiensis Jousseaume 1877, and the oldest reco...
