The study of Paleogene mammals intermediate and low latitudes has increased in the last decades been clearly demonstrated their importance comprehension evolution faunistic changes outside Patagonia.The these faunas permits establishing new comparisons among contemporaneous associations, completing distributional patterns, evaluating evolutionary lineages relation to climatic conditions prevailing each different regions.In this work we diversity Dasypodidae recovered from Geste Formation...
We present a detailed description of the anatomy dentary and lower teeth new specimen Callistoe vincei , large carnivorous metatherian from Eocene (?Ypresian) northwestern Argentina. The recently collected is young adult represented by partial right with canine, p1, roots p3, very well-preserved m1 to m4. includes comparison holotype specimen, much older individual, other closely related sparassodonts (e.g., Arminiheringia ). analysis this material allowed identifying plesiomorphic molar...
The Paleogene record of notoungulates in northwestern Argentina (NWA) is relatively abundant, including 20 species distributed 16 genera (Powell et al., 2011; Babot 2017). Fourteen th...
BIOSTRATIGRAPHIC CONSIDERATIONS.The aim of this work is to present the oldest record genus Chasicotatus in northwest Argentina and first a mammal, fluvio-lakeside sediments San José Formation (upper Miocene-middle Tortonian).It corresponds fragment dorsal carapace with articulated movable fixed osteoderms, which comes from proximity stream La Quenquiada, about 7 km southeast Amaicha del Valle, Tafí Valle department, Tucumán province, Argentina.The specimen assigned ameghinoi by external...
A new specimen of Pucatherium parvum from the lower levels Upper Lumbrera Formation Salta Province is reported. An almost complete dorsal carapace and several postcranial remains were preserved, providing important information about this particular taxon. The comparable in size to Dasypus novemcinctus, although osteoderms are very small. seems be completely integrated by movable osteoderms, a high degree mobility anteroposterior axis. There no evidence pseudoshield, scapular shield, or...
We report a new small podocnemidid, Gestemys powelli gen. et sp. nov., based on one nearly complete skull, lower jaw, two shells, and remains of the appendicular skeleton belonging to specimens from Eocene Geste Formation San Antonio de la Cobres Basin, Salta Province, north-western Argentina. As in other podocnemidid genera, exhibits fully developed medially extensive cavum pterygoidei, an incisura columellae auris enclosing stapes Eustachian tube, lacks exoccipital quadrate contact. bears...
We describe isolated remains of a Paleogene cingulate from El Simbolar locality, Upper Lumbrera Formation (Bartonian), southern Salta Province, northwestern Argentina. The material consists numerous fixed, movable, and caudal sheath osteoderms. specimen has large-sized osteoderms, with lageniform main figure, as in Utaetus buccatus, U. laxus, argos, ?U. deustus, Punatherium catamarcensis, the basal euphractin Archaeutatus. combination morphological characters, addition to its large size,...
