Dental microwear analysis in Gliridae (Rodentia): methodological issues and paleodiet inferences based on Armantomys from the Madrid Basin (Spain)

In the present study we analyze the microwear of the species included in the lineage Armantomys aragonensis-A. tricristatus of two samples from two middle Miocene localities from the Madrid Basin (El Cañaveral and Casa Montero). The methodological part of the study compares light stereomicroscope ph...
