Tetrapod toxic weaponry data

Dataset used for the paper 'tempo and mode of the evolution of venom and poison in tetrapods'. For each column, 1 denotes the presence of the trait, 0 denotes its absence, and NA denotes uncertainty (most often due to missing information in the literature, particularly where the species in question falls in an area of the phylogeny where the trait is both present and absent and not, for instance, nestled deeply within a unanimously venomous clade).
