Anurans (frogs, toads, escuerzos) have been an important part of terrestrial ecosystems since the Mesozoic era. Their bones, although relatively fragile, are frequently found as fossils, as well as in pellets, and carry useful taxonomic and ecological data, which in turn have the potential to inform about environmental and climatic conditions. However, these remains are often unidentified as such or, at best, identified as indeterminate anurans, thereby downplaying the value of isolated anuran bones. This situation has been fueled by the scarcity of specialists, but also by the lack of appropriate osteological collections and specialized literature that could provide tools for their study. With the aim of alleviating these shortcomings and hoping to spark interest in the study of amphibian osteology, we provide eight dichotomous keys (both in English and Spanish) for identifying isolated bones of medium- to large-sized anurans from Argentina, which make up most of its amphibian fossil record. In all cases, dichotomous keys allow for the successful identification of families and, in most cases, genera. A case study highlights the effectiveness of these keys in identifying a fossil Rhinella toad originally cataloged as Ceratophrys. We expect our dichotomous keys to be a useful tool for anyone dealing with the postcranial skeletal morphology of Neotropical anurans, including paleontologists, archaeologists, herpetologists, ornithologists, museum staff, and the general public.
