A baseline paleoecological study for the Santa Cruz Formation (late–early Miocene) at the Atlantic coast of Patagonia, Argentina
(Palaeogeography, Palaeoclimatology, Palaeoecology, 2010-06)Coastal exposures of the Santa Cruz Formation (late-early Miocene, southern Patagonia, Argentina) between the Coyle and Gallegos rivers have been a fertile ground for recovery of Miocene vertebrates for more than 100 years. ... -
Body Mass Prediction from Dental and Postcranial Measurements in Primates and Their Nearest Relatives
(2017)To evaluate alternative hypotheses for the role of mass and muscle-induced forces in joint construction, the allometric scaling relationships of the articular facets of the talus were estimated with phylogenetic regressions. ... -
Dietary inference from upper and lower molar morphology in platyrrhine primates.
(PLoS One, 2015)The correlation between diet and dental topography is of importance to paleontologists seeking to diagnose ecological adaptations in extinct taxa. Although the subject is well represented in the literature, few studies directly ... -
Endocranial volume and shape variation in early anthropoid evolution
(2014)Fossil taxa are crucial to studies of brain evolution, as they allow us to identify evolutionary trends in relative brain size and brain shape that may not otherwise be identifiable in comparative studies using only extant ... -
Intra and Interspecific Variation in Semicircular Canal Morphology in Primates and Implications for Locomotor Behavior Reconstruction Models
(2015)The semicircular canals of the vestibular system detect angular head rotations and play a fundamental role in guiding motor reflexes during locomotor behaviors. While extensive research has documented the relationship between ... -
Lemur Teeth in Three Keys: Dietary Adaptation, Ecospace Occupation, and Macroevolutionary Dynamics
(2019)Dietary adaptation appears to have driven many aspects of the high-level diversification of primates. Dental topography metrics provide a means of quantifying morphological correlates of dietary adaptation and can be used ... -
Mammalian faunas, ecological indices, and machine-learning regression for the purpose of paleoenvironment reconstruction in the Miocene of South America
(Palaeogeography, Palaeoclimatology, Palaeoecology, 2019-03-15)© 2019 Elsevier B.V. Reconstructing paleoenvironments has long been considered a vital component for understanding community structure of extinct organisms, as well as patterns that guide evolutionary pathways of species ... -
Ontogeny of Lower Limb Morphology and Proportions in the Dinaledi Hominins
(2015)The discovery of hundreds of fossil hominin remains from the Dinaledi Chamber of Rising Star cave in South Africa included dozens of immature elements attributed to multiple individuals. Some of these elements are amongst ... -
The Anatomy of Mastication in Extant Strepsirrhines and Eocene Adapines
(2008-04-25)The jaw adductor muscles in strepsirrhines were dissected and their fiber architecture was quantified. Bite force and leverage were estimated using values for physiological cross-sectional area (PCSA) of the jaw adductors ... -
The Cenozoic History of the Andean Foreland in Southeastern Peru
(2018)Results from two geographical study areas are presented in this dissertation, contributing important new information about the Cenozoic geological, environmental and biological regime. At the first locality along the Manu ... -
Tooth Root Size, Chewing Muscle Leverage, and the Biology of Homunculus patagonicus (Primates) from the Late Early Miocene of Patagonia
(Ameghiniana, 2010-09)Inferences about the diet of Miocene platyrrhine monkeys have relied upon the morphology of the molar teeth, specifically the crests on the molars. Using a library of Micro-CT images of a broad comparative sample of living ...
