Abstract Here we describe an unusual fossil assemblage found inside a crotovine from the late Pliocene Chapadmalal ‘Formation’ (Buenos Aires Province). This assemblage contains the greatest vertebrate diversity recovered inside an ichnofossil of this type, including skeletal remains of dasypodids, didelphids, procyonids, anurans and caviomorph rodents within coprolites and disaggregated scatological waste. We describe four general size types for crotovines and palaeoburrows found in the… Expand
SPARASSODONTA (METATHERIA) COPROLITES FROM THE EARLY-MID MIOCENE (SANTACRUCIAN AGE) OF PATAGONIA (ARGENTINA) WITH EVIDENCE OF EXPLOITATION BY COPROPHAGOUS INSECTS
TLDR
According to the features of the guild of carnivorous mammals from the Santa Cruz Formation, it is interpreted that hathliacynids and/or small borhyaenoids (Sparassodonta) are the most probable producers. Expand
Microvertebrates preserved in mammal burrows from the Holocene of the Argentine Pampas: a taphonomic and paleoecological approach
Abstract Microvertebrates are a major component of many assemblages recovered from the Quaternary of the Argentine Pampas. The main goal of this paper is to analyse the taphonomic history of aExpand
A Nearly Complete Juvenile Skull of the Marsupial Sparassocynus derivatus from the Pliocene of Argentina, the Affinities of “Sparassocynids”, and the Diversification of Opossums (Marsupialia; Didelphimorphia; Didelphidae)
TLDR
It is agreed that the appearance of carnivorously-adapted didelphids in South America during the late Miocene, including sparassocynins, is likely related to a decline in diversity of the sparassodonts at this time, and that the disappearance of these carnivorous- adaptations at the end of the Pliocene may have been due to the arrival of placental carnivorans from North America. Expand
Comparative osteology and functional morphology of the forelimb of Cyonasua (Mammalia, Procyonidae), the first South American carnivoran
TLDR
The morphology of Cyonasua would be well suited for digging and prey manipulation, allowing them to prey on small and relatively large‐sized vertebrates, as well as to avoid some of the predators that were dominant in the Cenozoic of South America. Expand
Megaichnus igen. nov.: Giant Paleoburrows Attributed to Extinct Cenozoic Mammals from South America
ABSTRACT In the last ten years, more than 1,500 large burrows have been discovered in southern and southeastern Brazil, dug in rocks that include weathered granitic and basaltic rocks, sandstones,Expand
Modern plains vizcacha (Lagostomus maximus, Chinchillidae, Rodentia) as a bone accumulating agent in the Argentine Pampas: Application to the study of fossiliferous sites
Abstract Lagostomus maximus (Rodentia, Chinchillidae), or Plains vizcacha, is a caviomorph rodent that inhabits semi-arid grasslands and desert scrub of central and northern Argentina, southernExpand
South American Fossil Carnivorans (Order Carnivora)
Carnivora is a clade of mammalian predators that evolved in northern continents during the Paleocene, and since the Miocene have invaded the southern continents (i.e., Africa and South America). TheyExpand
Ontogenetic variability in the limb bones histology of plains vizcacha (Lagostomus maximus, Chinchillidae, Rodentia): implications for life history reconstruction of fossil representatives
TLDR
It is considered that the mid-shaft of the humeri, femora and tibiae does not represent the most propitious sector to make the thin sections, since the modeling process there has erased part of the bone growth history of the individuals. Expand

TLDR
Any passive replacement or active displacement between the Hathliacynidae and carnivorous Didelphoidea are supported by the fossil record and a partition of the metatherian carnivorous guild seems to have occurred through to the Neogene. Expand
Functional morphology and palaeobiology of the pliocene rodent Actenomys (Caviomorpha: Octodontidae): the evolution to a subterranean mode of life
TLDR
Based upon the stratigraphic and sedimentological analysis of the palaeosoils containing its fossil remains, it is suggested that Actenomys lived in an environment of moderate to hig primary productivity, which has relevant implications for burrowing cost. Expand
