The phylogeny of coelacanths (Devonian-Recent) has been a matter discussion at least since 1940s following the discovery Latimeria chalumnae, and it remains as revisited issue in most recent works. In this contribution, an updated phylogenetic analysis based on new consensual data matrix is presented, merging emendations proposed over past two decades, including completely reviewed character scoring for some genera. Also, complete Stratigraphic Tree Analysis introduced, calibrating...
A new continental turtle, Tacuarembemys kusterae, gen. et sp. nov., is described on the basis of a partial external mold carapace and associated shell bone fragments recovered from Batoví Member (Late Jurassic–?earliest Cretaceous) Tacuarembó Formation, Paraná Basin, Uruguay. The estimated length 18 cm. This genus species shows unique combination characters: large nuchal notch, pair anterior supernumerary scales, absence cervical scale, an surface ornamentation that macroscopically smooth...
The association of vertebrate remains and invertebrate traces, although less studied than other bioerosion provides important paleoecological information. This report describes Cubiculum ornatum Roberts, Rogers, Foreman 2007 E., R. B. Foreman. 2007. Continental insect borings in dinosaur bone: examples from the Late Cretaceous Madagascar Utah. Journal Paleontology 81(1):201–208.[Crossref], [Web Science ®] , [Google Scholar], Osteocallis Scholar] unidentified traces dermal skeletal...
Today, the only living genus of coelacanth, Latimeria is represented by two species along eastern coast Africa and in Indonesia. This sarcopterygian fish nicknamed a "living fossil", particular because its slow evolution. The large geographical distribution may be reason for great resilience to extinction this lineage, but lack fossil records prevents us from testing hypothesis. Here we describe isolated bones (right angular, incomplete basisphenoid, fragments parasphenoid pterygoid) found...
<title>Abstract</title> Northwestern Argentina (NWA) contains, together with the Pampean region (PR), one of most complete late Neogene continental sequences, in which a great diversity palaeofauna was recognized, among glyptodonts stand out. Recent evidence suggests that Late Miocene period extra-Patagonian diversification southern South America for glyptodonts, perhaps stimulated by expansion C4 grasses and open environments (known as “Edad de las Planicies Australes”). Here we focus on...
Mawsonia constitutes one of the most conspicuous fossil coelacanth taxa, due to its unique anatomy and possible maximum body size. It typifies Mesozoic morphology, before putative disappearance group in record. In this work, three-dimensional cranial size estimations genus are re-evaluated from a recently described specimen Upper Jurassic deposits Uruguay. The 3D restoration was performed directly on material based anatomical information provided by living Latimeria previous two-dimensional...
A complex fossil association from the San Pedro Member of Camacho Formation (late Miocene) in Puerto Arazatí, José department, southern Uruguay, is documented this paper. Situated at base coastal cliffs, characterized by many land mammals, trace fossils indicative Psilonichnus Ichnofacies, and irregularly distributed oyster bioherms. The are interpreted as crab galleries, which represent a clear marginal, or even intertidal to supratidal episode within overall marine environment recognized...
Felids are the top predators in environments they inhabit. They entered South America at Pliocene-Pleistocene boundary, but their fossil record Uruguay, although informative, is scarce. In present contribution, three new materials (two hemimandibles and an isolated first lower molar) assigned to Panthera onca (Linnaeus, 1758) described. This material came from Quaternary sediments (Sopas, Dolores, Libertad Formations) several localities Uruguay. Based on this material, different aspects of...
