A palaeobiological window into the Lower Cretaceous Cupido Formation: Puerto México section, Nuevo Leon, Mexico por Torres de la Cruz, Felipe de Jesús, Chacón Baca, Elizabeth, Gómez Mancha, Yesica Edith, Cossío Torres, Tomás

“…The measured transect is correlated with a stratigraphic column logged in a nearby section. The preserved fossil biota represents marginal reef facies dominated by abundant rudist shells such as Douvillelia skeltoni, Toucasia sp., Offneria sp., and Amphitrocoelus sp. associated with relatively large colonial corals (with diameters up to 25 cm) like Stelidioseris sp. and to a lesser extent, with stromatoporoids. …”

INPUT HYPOTHESIS FOR OR AGAINST OUTPUT HYPOTHESIS? por García, Laura

“…Introduction Second language acquisition research has demonstrated that only exposure to L2 input is not sufficient to facilitate language acquisition and that the limited grammar instruction fostered by communicative and proficiency-based teaching approaches facilitates lexicalization of communication and fossilization of errors. If Widdowson's view of grammar "as a necessary communicative resource" is to be accepted, instead of grammar as a collection of forms and prescriptive rules, a new approach to grammar needs to be developed, not as a static system of rules to be memorized but as a dynamic system comprised of structures with an interconnected context dependent form, meaning, and use. …”

Análisis bio-estratigráfico y microfacial de la formación Zuloaga en la Cañada Alardín, General Zaragoza, Nuevo León, México por Rivera Estrada, Consuelo Araceli

“…Based on this data, a Geo-Archaeological investigation was carried out with the purpose of establishing the stratigraphic secuence of the area, distinguishing microfacies and the characteristic micro-fossils association, based on thin sections analysis from the Zuloaga Fm., in order to explaining the depositional environment.…”

Bioestratigrafía de la formación la peña, cretácico inferior, en base a foraminíferos (Clase Rhizopoda) del Cañón de la Huasteca, Santa Catarina, Nuevo León, México. por Córdoba Merino, Gabriela

“…ABSTRACT Biostratigraphy in the northeast of Mexico is mainly studied based on fossils macroscopic, being classically based on the succession of ammonites, so lack of microfossils-based research has prevented the determination precise biostratigraphic of sequences that lack these macrofossils; for this reason in this paper has been made an analysis integral biostratigraphic of high resolution, through the analysis of foraminifera of the La Peña formation in the Canyon of La Huasteca, Santa Catarina, Nuevo León, Mexico. …”
