Anais da Academia Brasileira de Ciências, 2014
The Brazilian Quaternary terrestrial Carnivora are represented by the following families: Canidae, Felidae, Ursidae, Procyonidae Mephitidae and Mustelidae. Their recent evolutionary history in South America is associated with the uplift of the Panamanian

First Description of the Auditory Region of a Tremarctinae (Ursidae, Mammalia) Bear: The Case of Arctotherium angustidens

Journal of Mammalian Evolution, 2013
Here we present the first detailed morphological study of the auditory region of a tremarctine bear, the South American giant short-faced bear Arctotherium angustidens. We compared 19 specimens of A. angustidens with other tremarctines and ursines.

Spectroscopic Characterization of Eoholocene Bones Found in a Cave in Northeast Brazil

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
The preservation of fossils depends on several interactions of organic and inorganic chemical processes. The hard parts, which are more suitable for fossilization, might record valuable information of biogenic processes, while the taphonomic characteristics supply information on postmortem chemical transformation.

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

Estimación de la masa corporal de las especies de osos fósiles y actuales (Ursidae, Tremarctinae) de América del Sur Body mass estimation of extinct and extant South American bears (Ursidae, Tremarctinae)

Revista del Museo Argentino de Ciencias Naturales, 2009
Contar con estimaciones precisas de la masa corporal de los taxones fósiles es esencial para realizar reconstrucciones paleobiológicas. Empleando relaciones demostradas entre la masa corporal y medidas anatómicas en mamíferos modernos algunos autores han
