Nuevas faunas de micromamíferos del Terciario continental de la Depresión Intermedia (provincia de Cuenca, España centro-oriental)

1986

In this paper the fossil content of nine new micromammal bearing localities and that of 15 levels in a borehole from the Loranca Basin (eastern Tague Basin, Prov. of Cuenca) is described. The age ranges from early Arvernian (Late Oligocene) to Turolian (Late Miocene). 47 rodent and lagomorph taxons have been found which are arranged in 8 biostratigraphic units. The Loranca-2 borehole contains 15 fossiliferous levels covering the Upper Oligocene/Lower Miocene. These additional data complete the faunal sequence published by Díaz & López(1919). The stratigraphic framework of the basin needs a revision because of the new faunal data.<br><br>Se presenta una serie de 9 nuevos yaci…

Quercomys bijmai gen. nov. sp. nov., a new dormouse of the subfamily Myomiminae, is described from the Oligocene/Miocene Boundary Interval of Santa Cilia (Huesca), Quel-1 and Fuenmayor-2 (La Rioja). Quercomys gen. nov. is characterized by its medium size, its hypsodont teeth, and its simple dental pattero. It is related to other genera, like Praearmantomys, Armantomys or Pseudodryomys , and its appearance is at a moment of high diversity of the family.

Taphonomic and Sedimentary Factors in the Fossil Record of Mammals

1990

The composition of the fossil assemblages of mammals (MFA) is traditionally considered as being controlled by historical factors. Its variations are attributed to biochronological changes due to evolutionary process or to biogeographic changes due to geodynamic process. The different MFA are compared as sampling units of similar nature. The presence or absence of taxa and their relative abundance are used as biochronologic and biogeographic indicators, and the samples (MFA) are considered homologous, although they appear in a different sedimentological, taphonomical, or tectonic context.
