Inferences of dietary preferences of Miocene squirrels (Xerinae, Sciuridae) from the Iberian Peninsula and Namibia using microwear analyses and ename…

2020

In this work, we compared microwear features and enamel thickness from upper molars (M1 and M2) of extinct Xerinae squirrels from the Miocene of Namibia (Vulcanisciurus sp) and the Iberian Peninsula (Atlantoxerus nov. sp. and Heteroxerus rubricati). We also examined the microwear from young and adult specimens of one extant squirrel, Atlantoxerus getulus, to compare it with the extinct species. Both, the microwear features and enamel thickness showed that the Miocene African species presented a more abrasive diet than the Iberian ones.

I RODITORI DI CAVA MONTICINO (BRISIGHELLA, RA)

2021

Rodents are the most abundant group of small mammals occurring in Brisighella deposits. They are represented by 12 species in total, among which 2 hamsters (Apocricetus cf. barrierei and Ruscinomys cf. lasallei), 2 dormice (Muscardinus sp. and Myomimus sp.), 1 porcupine (Hystrix (Hystrix) depereti), 2 sciurids (Atlantoxerus cf. rhodius and Hylopetes sp.) and 5 species of muridae (Apodemus cf. gudrunae, Centralomys benericettii, Occitanomys sp, Paraethomys meini and Stephanomys debruijni). This association suggests a relatively dry open environment, interrupted by forest environment with more or less dense underground.

I roditori sono il gruppo di micromammiferi più abbondante presente a Brisighella. Sono presenti 12 specie in totale: due cricetidi (Apocricetus cf. barrierei e Ruscinomys cf. lasallei) due gliridi (Muscardinus sp. e Myomimus sp.) un istrice (Hystrix (Hystrix) depereti) due sciuridi (Atlantoxerus cf. rhodius e Hylopetes sp.) e ben cinque specie di muridi (Apodemus cf. gudrunae Centralomys benericettii Occitanomys sp. Paraethomys meini e Stephanomys debruijni). Questa associazione suggerisce un ambiente aperto relativamente arido intervallato da spazi di foresta secca con sottobosco più o meno fitto.
