“…The constant sedimentary infilling of porosities and nutrient foramina indicates that the elements were completely lacking in soft tissue at the time of burial (Arribas and Palmqvist, 1998;Rustioni and Mazza, 2001). Generally, skeletal remains from SU7 are fully disarticulated, but specimens in anatomical connection are present in levels 7a and 7c, and bones clearly pertaining to the same individual were found in different squares of level 7b (associated but dispersed elements of Behrensmeyer, 1991) or in close proximity within level 7a (disarticulated but associated elements of Behrensmeyer, 1991).…”

Taphonomic analyses have been conducted on the macromammal remains found in Sedimentary Unit 7 of the lower Pleistocene Pirro 10 site of the Pirro Nord locality in Italy. Recent field research has concentrated on investigating the fossil content of this site and the genesis of the karst network and its related deposits. In the present study, we distinguish between preburial and synsedimentary (during burial) processes in order to group the vertebrate remains into different taphonomic categories according to their various states of preservation, thus introducing the concept of taphorecord-borrowed from invertebrate taphonomy-into macrovertebrate taphonomy for the first time. Element quantification, evaluation of transport effects, and state of preservation of the skeletal elements were studied and all elements separated into four taphorecords according to their relative chronology. The use of taphorecords also improves the accuracy of the data obtained from the various methods of element quantification. The analysis of bone sorting and orientation indicates that the fossiliferous deposits originated by water flows carrying both fossils and sediments, alternating with phases of carcass accumulation and reelaboration of bones from previously deposited layers. The study presented here serves as a proof of concept for the use of taphorecords in analyses of fossiliferous deposits in caves. INTRODUCTION AND GEOLOGIC SETTING

The South American Pleistocene mammal fauna includes great-sized animals that have intrigued scientists for over two centuries. Here we intend to update the knowledge on its palaeoecology and provide new evidence regarding two approaches: energetics and population density and relative abundance of fossils per taxa. To determine whether an imbalance exists, population density models were applied to several South American fossil faunas and the results compared to those that best describe the palaeoecology of African faunas. The results on the abundance study for Uruguay and the province of Buenos Aires during the Lujanian stage/age reveal that bulk-feeding ground sloths (Lestodon and Glossotherium) were more represented in the first territory, while the more selective Scelidotherium and Megatherium were more abundant in the second. Although the obtained values were corrected to avoid size-related taphonomic biases, linear regressions of abundance vs. body mass plots did not fit the expected either for first or second consumers. South American Pleistocene faunas behave differently from what models suggest they should. Changes in sea level and available area could account for these differences; the possibility of a floodplain in the area then emerged could explain seasonal changes, which would modify the calculations of energetics and abundance.

“…En las acumulaciones actuales de huesos producidas por carnívoros se ha observado una ausencia significativa de costillas y vértebras mientras que los huesos largos son muy abundantes (Brain 1981;Arribas y Palmqvst, 1998). En Huéla-go la proporción de vértebras y costillas (alrededor del 1%) es considerablemente menor que la de huesos largos (9,3%), y es semejante a la de Cúllar de Baza-l, donde la actividad y presencia de depredadores-carroñeros está bien documentada (Alonso .…”

Se analiza el ambiente sedimentario y los procesos y agentes de acumulación que contribuyeron a la formación del yacimiento Villafranquiense medio de Huélago. El conjunto fosilífero se depositó en los márgenes pantanosos de un sistema lacustre de aguas dulces con sedimentación carbonatada, donde las llanuras de fangos eran surcadas por corrientes aluviales de baja energía que desembocaban en la zona lacustre. Se reconocen varios ciclos de inundación que condicionaron la distribución espacial y composición de los restos óseos. Huélago representa una acumulación mixta de restos removilizados y transportados por corrientes aluviales junto con materiales depositados in situ. En los niveles detríticos asociados a paleocanales hay un porcentaje mayor de dientes aislados y esquirlas; y las mandíbulas y cuernas están asociadas a niveles limoso-margosos sin removilizar. Los agentes atmosféricos contribuyeron activamente a la fracturación de los huesos. La actividad de carroñeros-predadores en la superficie herbácea y encharcada del borde del lago ha sido reconocida. La gran diversidad de rumiantes, en particular los ramoneadores, indica áreas arboladas o arbustivas en los alrededores de Huélago, aunque no en el área inmediata del borde del lago. Se elaboró una matriz de datos con las variables medidas en cada resto fósil recuperado, que fue la base para el tratamiento gráfico y estadístico utilizado en el estudio del yacimiento. ABSTRACTThis work analyses the sedimentary environment and accumulative natural agents that contributed to the Huélago site formation (Middle Villafranchian). The fossiliferous assemblage was accumulated in the paludine fringe of a calcareous, fresh water lacustrine system. The mud-flats were crossed by low energy alluvial currents with outlets in the lacustrine area. Several floods have been recognized that conditioned the spatial distribution and composition of the bone remains. Huélago shows a mixture of bones transported by alluvial currents together with remains deposited almost in situ. The percentage of isolated teeth and sprinters is higher in the paleochannels, whereas horns and maxillas are found mainly within the marllevels. Weathering was a decisive factor in the fracturation of the bone assemblage. Predator-scavenger activity in the herbaceous swamped margins of the lacustrine area has been found. The great diversity of ruminant artiodactyls, in particular browsers is indicative of wooded or bushy areas in the surroundings of Huélago, although not in the immediate area of the lake. A data base compiled the several variables measured for each recovered bone and provided information for the statistical and graphic programs used in the study of the Huélago site.
