Multidisciplinary investigations on the origins and evolution of the extinct ungulate order Notoungulata (Mammalia: Placentalia) and the extinct muskox genus Bootherium (Mammalia: Artiodactyla: Bovidae) [PDF]
, 2017 This dissertation is an exploration of phenomena on varying scales, built on the backbone of Cenozoic mammalian biochronologic units (Land Mammal ‘Ages’): the integration of fossil and geological data to constrain spatiotemporal patterns in evolution.

Dentro del Orden Notoungulata, considerado el clado más diverso y abundante de ungulados nativos de América del Sur, Interatheriidae (Paleoceno tardío–Mioceno Tardío) es una de las familias más conocidas y derivadas. La mayoría de los interatéridos descritos a fines del siglo XIX fueron erigidos a partir de especímenes recolectados en la prolífera ...

Three new trace fossils are described from Miocene paleosols of southern Argentina. Celliforma pinturensis, n. ichnosp. and Celliforma rosellii, n. ichnosp. are interpreted as cells of digging bees, possibly Anthophoridae, and Coprinisphaerafrenguellii, n. ichnosp. are brood balls of dung‐beetles. Both burrowing bees and dung‐beetles are common nesters

ABSTRACTCoprolites are a useful tool to obtain information related to the life history of the producer, trophic interactions, biodiversity, paleoenvironments, and paleoclimate, among other issues. We analyze here a sample of 111 coprolites recovered from levels of the Santa Cruz Formation (lower–middle Miocene, Burdigalian–early Langhian), outcropping ...

Paleobiological Integration of Santacrucian Sloths (Early Miocene of Patagonia)
Ameghiniana, 2016Abstract. Paleobiological integration proceeds from descriptive morphology and paleosynecological reconstruction. This integration is achieved through modeling of function, inference of faculties, performance and resource use to hypothesize about fundamental niche.
