Crotalus molossus oaxacus, or the Oaxacan black-tailed rattlesnake, is a subspecies of black-tailed rattlesnake which is native to its namesake, Oaxaca, Mexico.[1] As with all rattlesnakes, it is venomous.[2] While it is currently recognised as a subspecies, it has been suggested to be further researched and reviewed as a species by Muñoz-Mora et al. due to its being the basal and most divergent clade of the species, splitting around 7.5 million years ago in the Miocene.[3]
