Resumo: | ABSTRACT: Bos and bison Bison (Bovinae, Mammalia) are closely related large mammals abundant in Pleistocene fossil assemblages. The determination of osteological elements of these bovines is traditionally based on morphological differences, but new molecular studies suggest the synonymy of both genera. Following recent advances in morphological classifying methods we implemented a two-dimensional geometric morphometric approach to analyse the occlusal surface of molars in Bos and Bison, and secondly on extinct bison species. We have applied this methodology in photographs of upper and lower molars using our new templates proposals to digitise the morphology. The digitalisation of the landmarks and semilandmarks was carried out with Viewbox 4 software and the statistical analysis with Morphologika2 2.5 and MophoJ softwares. Our results show an overlapping distribution regarding the main aspects of shape of the molars, with no discrimination between taxa. This can be due to the small sample size, and/or the different wear stages. |

A determinação dos elementos osteológicos destes bovinos é tradicionalmente baseada em diferenças morfológicas, contudo, novos estudos moleculares sugerem a sinonímia de ambos os géneros. Na sequência dos recentes avanços nos métodos de classificação morfológica, implementámos uma abordagem de morfometria geométrica bidimensional para analisar a superfície oclusal dos molares de Bos e Bison, e posteriormente, de espécies de bisontes extintas. Aplicámos esta metodologia em fotografias de molares superiores e inferiores utilizando os nossos novos protocolos para digitalizar a morfologia. A digitalização dos landmarks e semi-landmarks foi realizada com o software Viewbox 4 e a análise estatística com os softwares Morphologika2 2.5 e MophoJ. Os nossos resultados apresentam uma sobreposição na distribuição dos principais aspectos relativos à forma dos molares, sem qualquer diferenciação entre taxas. Isto poderá dever-se ao pequeno tamanho da amostra, e/ou às diferentes fases de desgaste.LNEG - Laboratório Nacional de Energia e GeologiaRepositório do LNEGGalli, EmiliaFidalgo, DaríoGarcía-Martínez, DanielRosas, Antonio2022-05-04T15:13:34Z2021-06-01T00:00:00Z2021-06-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.9/3834engGalli, Emilia...
