Se dan a conocer los vegetales fósiles (macrorrestos foliares, frutos y palinomorfos) y una asociación de
microvertebrados encontrados en yacimientos descubiertos en la “Unidad Intermedia” del Mioceno de Madrid.
Los restos paleobotánicos y palinológicos se encuentran en cinco yacimientos, mientras que los de microvertebrados aparecen en otro distinto, cercano a los anteriores y estratigráficamente por encima de éstos.
En general la palinoflora identificada es bastante uniforme en todos los yacimientos; no así la macroflora que
presenta peculiaridades en alguno de ellos. Los datos paleobotánicos ponen de manifiesto una vegetación muy
diversa con géneros y especies característicos de medios montanos, abanicos aluviales, márgenes lacustre-palustres
y lagunares. Los resultados del estudio de la macroflora y de los palinomorfos se representan y ubican en un perfil sintético y en un bloque diagrama esquemático.
[ABSTRACT]
Some palaeobotanical assemblages (spores, pollen, leaves, seeds and fruits) and microvertebrates found in the
“Unidad intermedia” from middle Miocene deposits of the Madrid basin are studied.
The fossil plants appear in five sites, and the vertebrate fossils in other site, near the formers, but
stratigraphically above these. The palynological assemblages are quite similar in all the sites, but the macroremains
associations present taphonomic peculiarities in some of them.The fossil plants identified show some elements
of acuatic, flooded, riparian and of river banks environments with some deciduous and evergreen forest taxa.
The palaeobotanical data are symbolized and ecologically located in a syntetic section and in a diagram. The
different environments which had been delimited are represented.
The vertebrate fossil assemblage is made of two taxa of Reptilia (one Lacertidae and one Anguidae), and,
among the mammals, the Sciuridae Heteroxerus cf. rubricati, the Gliridae cf. Armantomys sp., the Cricetidae
Megacricetodon collongensis - crusafonti, one Insectivora and some remains of Lagomorpha. From a biostratigraphical point of view, this faunal assemblage may corresponds to the Middle Miocene, to the Upper Aragonian, but not to latest among the Zones F, G1 and G2 (sensu Daams and Freudenthal, 1988a) that can be correlated with the NM 6 Unit (sensu Mein, 1975). This fauna suggests a mainly open environment and a relatively dry climate.
