Paleohistología y permineralización de dos saurópodos del ciclo Jurásico en la subcuenca de Galve (Teruel, España)
Jurado, C. ; Bauluz, Blanca (Universidad de Zaragoza) ; Castanera, D. ; Canudo, J.I. (Universidad de Zaragoza)
Resumen: En este trabajo se realiza una aproximación a la paleohistología de dos dinosaurios saurópodos, Galvesaurus herreroi Barco et al., 2005 y un saurópodo indeterminado. El primero procede del yacimiento Cuesta Lonsal de Galve (Teruel) de edad Kimmeridgiense superior mientras que el segundo se ha encontrado en el yacimiento La Peñuela en Camarillas (Teruel) cuya de edad es Berriasiense. Las observaciones histológicas realizadas a partir de láminas delgadas de los restos óseos en microscopio óptico, han permitido determinar el estadio ontogenético de los saurópodos en el momento de su muerte, tratándose en Galvesaurus y el saurópodo de La Peñuela de ejemplares adulto y senil, respectivamente. Así mismo, se ha realizado un estudio mineralógico de las muestras paleohistológicas combinando la microscopía óptica y electrónica de barrido de emisión de campo (FESEM). En el estudio se observa que los procesos diagenéticos son similares en los restos óseos de los dos ejemplares. El apatito que compone los huesos no ha sido modificado durante la diagénesis. Los rellenos en los canales y cavidades vasculares son mayoritariamente cementos calcíticos, granos detríticos y óxidos. El hecho de que los procesos observados sean similares en los distintos individuos se debe probablemente a la similitud litológica y de historia geológica de las formaciones en las que los ejemplares fueron encontrados.
In this work a paleohistological approach to two sauropod dinosaurs, Galvesaurus herreroi Barco et al., 2005 and an undescribed specimen have been performed. The former comes from the Cuesta Lonsal site in Galve (Teruel) and it is late Kimmeridgian in age whereas the latter have been found in La Peñuela site in Camarillas (Teruel) and it is Berriasian in age. The histological observations of the skeletal remains that were made from the thin sections in an optical microscope have allowed to determine the ontogenetic stage of the sauropods at the time of their death: Galvesaurus and the sauropod of La Peñuela were adult and senile specimens, respectively. A mineralogical study of the paleohistological samples has also been carried out, combining optical and field emission scanning microscopy (FESEM). In the study it is observed that the diagenetic processes are similar in the bone remains of the two specimens. The apatite of the bones has not been modified during diagenesis. The fillings in vascular channels and cavities are mainly calcite cements, detrital grains and oxides. The fact that the observed processes are similar in the two individuals is probably due to the lithological similarity and the geological history of the formations in which the specimens were collected.
