Taphonomy is a conceptual subsystem of paleontology which strives to ascertain how the fossil record has
been produced and what sort of modification it has undergone. Taphonomy has its own concepts that allow
the fossil record to be dissociated conceptually from the geological or stratigraphicai record. It is also possible
to regard fossils (or recorded-entities of different organizational levels) and corresponding organisms (or
paleobiologicaJ entities) as being distinct in nature. The aim of taphonomical studies is the fossils, i.e. the
recorded·entities, and not the strata that bear them or the paleobiological entities they represent. Taphonomical
data are necessary for paleobiological interpretations, and are relevant in applied paleontology. It is
necessary, however, to develop a systematic approach to fossils that takes into account logical and epistemological
assumptions used in biology and paleobiology. By identifying integrated systems with taphonomicalpaleobiological
relationships, new problems in paleontology can be raised and solved. In order to obtain H
biochronological framework, it is only necessary to identify and classify systematically into units the different
kinds of topologically successive recorded-entities. These concepts are neither incompatible nor contradictory
to those in biostratigraphy and chronostratigraphy, and may serve to e lucidate their fundamental basis.
La Tafonomia es un subsistema conceptual de la Paleontologia cuyo objetivo es averiguar como ha sido
producido y que modificaciones ha experimentado el registro fosil. La Tafonomia dispone de conceptos
propios que permiten disociar conceptualmente el registro fosil del registro estratigrMico 0 del registro
geologico. Tambien es posible considerar como de distinta naturaleza a las fosiles (0 a las entidadesregistradas
de diferente nivel de organizacion) y a los correspondientes organismos (0 entidades paleobiologicas).
El objeto de estudio en las investigaciones tafonómicas son los fosiles, las entidades registradas, y no los
estratos en los que se encuentran 0 las entidades paleobiologicas que representan. Los datos tafon6micos son
necesarios para las interpretaciones paleobiol6gicas, y son relevantes en Paleontologia aplicada. Sin embargo,
es necesario desarrollar u n planteamiento sistemista para el estudio de 105 f6siles, en el que se tenga en
cuenta 105 presupuestos logicos y epistemológicos utilizados en Bioiogia y Paleobiologia. Al identificar
sistemas integrados con relaciones tafonomico-paleobiologicas es posible plantear y resolver nuevos problemas
en Paleontologia. Para obtener un marco de referencia temporal biocronologico solo es necesario identificar y
clasificar sistematicamente en unidades las diferentes clases de entidades-registradas topológicamente sucesivas. Estos conceptos no son incompatibles ni contradictorios con los utilizados en Bioestratigrafia y Cronoestratigrafia,
y pueden servir para elucidar los fundamentos teoricos de cada uno de estos sistemas conceptuales.
