Jaw shape and mechanical advantage are indicative of diet in Mesozoic mammals
Jaw morphology is closely linked to both diet and biomechanical performance, and jaws are one of the most common Mesozoic mammal fossil elements. Knowledge of the dietary and functional diversity of early mammals informs on the ecological structure of palaeocommunities throughout the longest era of mammalian evolution: the Mesozoic. Here, we analyse how jaw shape and mechanical advantage of the masseter (MAM) and temporalis (MAT) muscles relate to diet in 70 extant and 45 extinct mammalsdoi:10.1038/s42003-021-01757-3 pmid:33623117 pmcid:PMC7902851 fatcat:tb3osymvrzadjkavtfcylgy354
