Abstract Araucarioxylon Kraus is a widely known fossil‐genus generally applied to woods similar that of the extant Arau‐ cariaceae. However, since 1905, several researchers have pointed out this name an illegitimate junior nomenclatural synonym. At least four generic names are in current use for fossil wood type: Agathoxylon Hartig, , Dadoxylon Endl. and Dammaroxylon J. Schultze‐Motel. This problem inconsistent application compounded by fact type represent wide range plants including basal...

We present new data on the paleoichthyology, paleobotany and radiometric results of Loreto Formation in Brunswick Peninsula southernmost Chile, that allow us to propose a Late Eocene age. The rich diversity fossil cartilaginous fishes (Chondrichthyes, Elasmobranchii) recognized upper levels this unit includes taxa Carcharias aff. ‘hopei’ (Agassiz), Odontaspis sp., Carcharoides catticus (Philippi), Striatolamia macrota Anomotodon Macrorhizodus praecursor (Leriche), Galeorhinus...
This study presents the first record of Eocene birds from western margin southernmost South America. Three localities in Magallanes, southern Chile, have yielded a total eleven bird remains, including Sphenisciformes (penguins) and one tentatively assigned to cf. Ardeidae (egrets). Two different groups penguins been recognized these localities. The group is similar size smallest taxa previously described Seymour Island, Marambiornis Myrcha et al., 2002, Mesetaornis Delphinornis Wiman, 1905....
A succession of marine and continental strata on the southern flank Cerro Cono in Sierra Baguales, northeast Torres del Paine, can be correlated with stratigraphic units exposed along border Lago Argentino region Santa Cruz Province, Argentina. These include Estancia 25 de Mayo Formation basal part Formation. The lithological correlation is also confirmed by detrital zircon ages (maximum age 18.23±0.26 Ma) a rich assemblage terrestrial vertebrate fossils, biostratigraphically...
Hay muy pocos trabajos sobre la estratigrafia y sedimentologia de Formacion Rio Baguales del Oligoceno superior-Mioceno inferior en Provincia Magallanes sur Chile, luego su primera definicion 1957. Se presenta un perfil estratigrafico detallado parte superior formacion al oeste rio Baguales, con una interpretacion los ambientes depositacion. identifico costa progradante facies boca estuario, medio estuario (laguna) delta cabecera. Las grandes capas frontales talud deltaico indican...
Abstract Ten embedded fossil logs sampled in situ from the middle Eocene volcano‐sedimentary rocks close to Suffield Point Fildes Peninsula, King George Island, Antarctica, are assigned Protopodocarpoxylon araucarioides Schultze‐Motel ex Vogellehner, Phyllocladoxylon antarcticum Gothan, Agathoxylon (Poole & Cantrill) Pujana et al ., A . pseudoparenchymatosum (Gothan) and an unidentified angiosperm wood. Differences taxonomic representation growth‐ring characters of woods on Island coeval...
El objetivo principal de este estudio fue valorar un modelo pedagógico y su estrategia implementación para la formación ambiental en licenciatura educación inicial. Se integra lo académico, investigación vinculación. La metodología descriptiva explicativa, con enfoque mixto, desarrollada tres fases. utilizaron encuestas, entrevistas, grupos focales pre-experimento. muestreo, no probabilístico intencional, incluyó 20 estudiantes, siete profesores carrera, 30 otras carreras, cinco directivos...
