Incisor Enamel Microstructure of Hystricognathous and Anomaluroid Rodents from the Earliest Oligocene of Dakhla, Atlantic Sahara (Morocco)
(Springer, 2019-09)
Seven hystricognaths and five anomaluroids have been recently described from the earliest Oligocene of the Dakhla (DAK C2) region of Morocco, based primarily on isolated cheek teeth. Here, we analyzed the enamel microstructure ...
New rhynchocephalian specimen in the Late Triassic of southern Brazil and comments on the palatine bone of Brazilian rhynchocephalians
(Taylor & Francis Ltd, 2019-04)
Triassic rhynchocephalians from South America are relatively sparse, based on one taxon from the Norian of Argentina (i.e., Sphenotitan leyesi) and three records from the Late Carnian (i.e., indet. taxon) and Norian (i.e., ...
The Allemann collection from the Santa Cruz Formation (late early Miocene), Argentina, in Zurich, Switzerland
(Springer, 2019-11)
One of the best-known faunal assemblages that characterizes the past ecosystems from South America comes from the Santa Cruz Formation in Argentina. This assemblage is formed by an endemic fauna, which included ground ...

An exceptionally well-preserved skeleton of Palaeothentes from the Early Miocene of Patagonia, Argentina: new insights into the anatomy of extinct paucituberculatan marsupials
(Springer, 2014-05)
During the Cenozoic paucituberculatans were much more diverse taxonomically and ecomorphologically than the three extant genera of shrew-like marsupials. Among paucituberculatans, palaeothentids were abundant during the ...
Late early Miocene caviomorph rodents from Laguna del Laja (~37° S), Cura-Mallín Formation, south-central Chile
(Pergamon-Elsevier Science Ltd, 2020-05-31)
Despite recent efforts, the paleodiversity of the Neogene mammals in Chile remains poorly known, with several putative new species awaiting description. For example, previous studies suggest that the early to late Miocene ...
A new sauropod titanosaur from the Plottier Formation (Upper Cretaceous) of Patagonia (Argentina)
(Universidad de Barcelona, 2011-03)
This paper presents a new titanosaur sauropod, collected from levels of reddish clays assigned to the Plottier Formation (Coniacian-Santonian). The holotype of Petrobrasaurus puestohernandezi gen. et. sp. nov. is a ...
Skates and rays (Elasmobranchii, Batomorphii) from the Eocene La Meseta and Submeseta formations, Seymour Island, Antarctica
(Taylor & Francis, 2019-09)
Eocene deposits of the famous La Meseta Formation of Seymour Island, Antarctic Peninsula, yielded the most diverse Paleogene fossil elasmobranch association of the Southern Hemisphere. In this assemblage, sharks clearly ...
First skeleton of the notoungulate mammal Notostylops murinus and palaeobiology of Eocene Notostylopidae
(Wiley Blackwell Publishing, Inc, 2019-04)
Here, we describe the first skeletal remains of Notostylops recovered from middle Eocene levels of the Sarmiento Formation, Patagonia, Argentina. The remains include two teeth of Notostylops murinus, the axis, vertebral ...
