    Morphological taphonomic transformations of fossil bones in continental environments, and repercussions of their chemical composition
    (Wiley-Blackwell, 2002) Fernández Jalvo, Yolanda; Sánchez Chillón, B.; Andrews, Peter; Fernández López, Sixto Rafael; Alcalá Martínez, L.
    The aim of this paper is to provide a summary of structural or surface modifications of vertebrate bone remains in continental palaeoenvironments that may have repercussions on their chemical composition. Both before and after burial, a different set of physical, chemical and biological agencies may produce modifications of the bone morphological structure and/or bone chemical composition. Several of these morphological modifications are diagnostic of particular agents, which otherwise may not be noticed or identified in a fossil association. In order to understand diagenesis, those events that occurred before final burial have to be considered, as they may strongly modify the bone morphological structure and influence post-burial changes.

    Tafonomía, fosilización y yacimientos de fósiles: modelos alternativos
    (Asociación Española para la enseñanza de las Ciencias de la Tierra, 2001) Fernández López, Sixto Rafael
    La Tafonomía es un subsistema conceptual de la Paleontología cuyo objetivo es averiguar cómo ha sido producido y qué modificaciones ha experimentado el registro fósil. Teniendo en cuenta un planteamiento sistemista y evolucionista se puede desarrollar un modelo alternativo de la fosilización: el modelo de modificación tafonómica y retención diferencial vs. el modelo de modificación paleobiológica y destrucción selectiva. Durante la fosilización aparecen representantes de nuevos grupos tafonómicos, que tienen diferente composición y estructura respecto a los elementos biogénicamente producidos. En cada estadio del proceso de fosilización persisten los grupos tafonómicos (o tafones) cuyos elementos se han estabilizado, transformado y replicado con mayor eficacia en las etapas anteriores, no los elementos conservados que inicialmente eran más resistentes ni los que han sido menos afectados por factores ambientales. [ABSTRACT] Taphonomy is a conceptual subsystem of Palaeontology which strives to ascertain how the fossil record has been produced and what sort of modifications it has undergone. An alternative model to that traditionally used in Taphonomy can be developed taking into account a systemic and evolutionary approach: the model of taphonomic modification and differential retention vs. the model of palaeobiological modification and selective destruction. Representatives ofnew taphonomic groups appear during fossilization processes. Components of these taphonomic groups show different composition and structure from those biogenically produced, and they increase de diversity of the fossil record. In every fossilization stage the persisting taphonomic groups (or tapha) will be those whose preserved elements have been stabilized, transformed, and replicated with a higher efficiency in the prior stages, but not the most resistant or those preserved elements less affected by environmental factors
