Email: [email protected] Editor: Graciela S. Bressan y Diana E. Fernández Recibido: 12 de mayo de 2019 Aceptado: 2 de agosto de 2019 ABSTRACT Crustacean microcoprolites are abundant constituents in the Upper Jurassic–Lower Cretaceous of the Neuquén Basin (Argentina). A new record of these particles is described from the lowermost Olcostephanus (O.) atherstoni ammonite Zone (lower Valanginian) in the Mulichinco Formation at Puerta Curacó section, north of the Neuquén province. Coprolites come from shallow-water oyster-dominated biostromes and belong to a new ichnospecies, Palaxius chosmalalensis n. isp., which was previously described as P. decemlunulatus (Paréjas) from the Upper Cretaceous of Egypt. As a consequence of the description of the new ichnospecies, we propose to incor- porate quantitative criteria regarding the angle with which the canals are oriented, as well as its position with respect to the center of symmetry of the coprolite. Keywords: pellets, Callianassidae, ichnology, Cretaceous. RESUMEN Palaxius chosmalalensis n. isp., un nuevo microcoprolito de crustáceos del Cretácico Inferior de la Cuenca Neuquina, Argen- tina.

Reveals That Glyptodonts Evolved from Eocene Armadillos

Although glyptodonts were an important component of Cenozoic South American faunas, their early evolution and phylogenetic affinities within the order Cingulata (armoured New World placental mammals) remain controversial. In this study, we used hybridization enrichment and high-throughput sequencing to obtain a partial mitochondrial genome from Doedicurus sp., the largest (1.5 m tall, and 4 m long) and one of the last surviving glyptodonts. Our molecular phylogenetic analyses revealed that glyptodonts fall within the diver- sity of living armadillos. Reanalysis of morphological data using a molecular ‘back- bone constraint’ revealed several morphological characters that supported a close relationship between glyptodonts and the tiny extant fairy armadillos (Chlamyphori- nae). -

A Stable Isotopic Investigation of Resource Partitioning Among Neosauropod Dinosaurs of the Upper Jurassic Morrison Formation
A stable isotopic investigation of resource partitioning among neosauropod dinosaurs of the Upper Jurassic Morrison Formation Benjamin T. Breeden, III SID: 110305422 [email protected] GEOL394H University of Maryland, College Park, Department of Geology 29 April 2011 Advisors: Dr. Thomas R. Holtz1, Jr., Dr. Alan Jay Kaufman1, and Dr. Matthew T. Carrano2 1: University of Maryland, College Park, Department of Geology 2: National Museum of Natural History, Department of Paleobiology ABSTRACT For more than a century, morphological studies have been used to attempt to understand the partitioning of resources in the Morrison Fauna, particularly between members of the two major clades of neosauropod (long-necked, megaherbivorous) dinosaurs: Diplodocidae and Macronaria. While it is generally accepted that most macronarians fed 3-5m above the ground, the feeding habits of diplodocids are somewhat more enigmatic; it is not clear whether diplodocids fed higher or lower than macronarians. While many studies exploring sauropod resource portioning have focused on differences in the morphologies of the two groups, few have utilized geochemical evidence. Stable isotope geochemistry has become an increasingly common and reliable means of investigating paleoecological questions, and due to the resistance of tooth enamel to diagenetic alteration, fossil teeth can provide invaluable paleoecological and behavioral data that would be otherwise unobtainable. Studies in the Ituri Rainforest in the Democratic Republic of the Congo, have shown that stable isotope ratios measured in the teeth of herbivores reflect the heights at which these animals fed in the forest due to isotopic variation in plants with height caused by differences in humidity at the forest floor and the top of the forest exposed to the atmosphere. -

New Glyptodont from the Codore Formation (Pliocene), Falc6n State, Venezuela, its relationship with the Asterostemma problem, and the paleo- biogeography of the Glyptodontinae. - Palaontologische Zeitschrift 82 (2): 139-152, 3 figs., Stuttgart, 30. 6. 2008. Abstract: One of the basal Glyptodontidae groups is represented by the Propalaehoplophorinae (late Oligocene - mid- dle Miocene), whose genera (Propalaehoplophorus, Eucinepeltus, Metopotoxus, Cochlops, and Asterostemma) were initially recognized in Argentinian Patagonia. Among these, Asterostemma was characterized by its wide latitudinal distribution, ranging from southernmost (Patagonia) to northernmost (Colombia, Venezuela) South America. How- ever, the generic assignation of the Miocene species from Colombia and Venezuela (A.? acostae, A. gigantea, and A. venezolensis) was contested by some authors, who explicitly accepted the possibility that these species could corre- spond to a new genus, different from those recognized in southern areas. A new comparative study of taxa from Argen- tinian Patagonia, Colombia and Venezuela (together with the recognition of a new genus and species for the Pliocene of the latter country) indicates that the species in northern South America are not Propalaehoplophorinae, but represent the first stages in the cladogenesis of the Glyptodontinae glyptodontids, the history of which was heretofore restricted to the late Miocene - early Holocene of southernmost South America. -

[email protected] ABSTRACT. Paleogene records of Cingulata Glyptodontidae are scarce. The only well described comes from the Paleogene of Argentine Patagonia. Two subfamilies have been reported for that period: Glyptatelinae and Propalaehoplophorinae. Until this contribution, the latter taxon was geographically restricted to the locality of El Pajarito (Late Oligocene, Deseadan SALMA), Chubut province, Argentina. Here we present and describe the northernmost record of a Paleogene Propalaehoplophorinae. The material is represented by three associated osteoderms of the dorsal carapace from the Fray Bentos Formation (Late Oligocene, Deseadan SALMA) in the locality of Cueva del Tigre, Chajarí, Entre Ríos province, Argentina. -
