| comparative jaw muscle anatomy in kangaroos, wallabies, and rat-kangaroos (marsupialia: macropodoidea). | the jaw muscles were studied in seven genera of macropodoid marsupials with diets ranging from mainly fungi in potorous to grass in macropus. relative size, attachments, and lamination within the jaw adductor muscles varied between macropodoid species. among macropodine species, the jaw adductor muscle proportions vary with feeding type. the relative mass of the masseter is roughly consistent, but grazers and mixed-feeders (macropus and lagostrophus) had relatively larger medial pterygoids and s ... | 2009 | 19462457 |
| [topography and structure of the stylohyoid muscle in mammals]. | topography and structure of the musculus stylohyoideus (msh) have been studied in 78 species of mammalia from 12 orders. the muscle in question has specific peculiarities not only in its position and fixation, but also in a great variability of its structure. the msh is not revealed in philander opossum, lagostrophus fasciatus, guinea pig, meriones eversmanni, rhombomys opimus, nyctereutes procyonoides, thos aureus, mastelidae. various pathways of development and different functional loading def ... | 1988 | 3408352 |
| reconstructing the evolution of giant extinct kangaroos: comparing the utility of dna, morphology, and total evidence. | combined "total evidence" analysis of molecular and morphological data offers the opportunity to objectively merge fossils into the tree of life, and challenges the primacy of solely dna based phylogenetic and dating inference, even among modern taxa. to investigate the relative utility of dna, morphology, and total evidence for evolutionary inference, we sequenced the first near-complete mitochondrial genomes from extinct australian megafauna: a 40-50 thousand year old giant short-faced kangaro ... | 2019 | 30481358 |
| late pleistocene australian marsupial dna clarifies the affinities of extinct megafaunal kangaroos and wallabies. | understanding the evolution of australia's extinct marsupial megafauna has been hindered by a relatively incomplete fossil record and convergent or highly specialized morphology, which confound phylogenetic analyses. further, the harsh australian climate and early date of most megafaunal extinctions (39-52 ka) means that the vast majority of fossil remains are unsuitable for ancient dna analyses. here, we apply cross-species dna capture to fossils from relatively high latitude, high altitude cav ... | 2015 | 25526902 |
