Feeding ecology of Late Pleistocene Muntiacus muntjak in the Padang Highlands (Sumatra)
The Dubois Collectie comprises around 1000 isolated fossil teeth of Muntiacus muntjak from the Padang Highlands in Sumatra. The majority were retrieved from one of the three fossil cave sites Lida Ajer, Sibrambang or Jambu. Lida Ajer is the only cave, for which exact location, geology as well as the...

Summary: | The Dubois Collectie comprises around 1000 isolated fossil teeth of Muntiacus muntjak from the Padang Highlands in Sumatra. The majority were retrieved from one of the three fossil cave sites Lida Ajer, Sibrambang or Jambu. Lida Ajer is the only cave, for which exact location, geology as well as the age of the fossiliferous deposits are known. Using the mesowear method, we searched for differences in the dietary signal of Muntiacus muntjak and thus in the paleoenvironments of the three caves. Muntiacus muntjak from either one of the caves does not differ significantly in the composition of its diet, showing a mixed feeder signal. The samples of Lida Ajer and Sibrambang illustrate an increase of the mixed feeding component, which could be the result of higher seasonality.
La collection Dubois comporte environ 1000 dents fossiles isolées de Muntiacus muntjak, en provenance des Highlands de Padang à Sumatra. La majorité ont été récoltées dans trois grottes, Lida Ajer, Sibrambang et Jambu. Lida Ajer est la seule grotte dont on connaisse la localisation exacte, la géologie ainsi que l’âge des dépôts fossilifères. En utilisant la méthode de denture « Mesowear », on tente de trouver des différences dans le signal alimentaire de Muntiacus muntjak, et ainsi dans les paléoenvironnements des trois grottes. Muntiacus muntjak ne se distingue de façon significative d’aucun individu issu des autres grottes dans la composition de sa nourriture, se révélant ainsi un mangeur de nourriture mixte. Les échantillons de Lida Ajer et Sibrambang illustrent l’augmentation de composants d’alimentation mixte, qui pourrait résulter d’un plus net caractère saisonnier de la nourriture. |
