It is found in central and northern Argentina, Uruguay, southern Brazil, and southern Paraguay. It is tetraploid; diploid populations have been described as a new species, Odontophrynus cordobae.[1][2] Odontophrynus americanus is common throughout much of its range. It occurs in open grasslands and savannas. It is a fossorial species, but during the breeding season, these frogs are found at shallow, temporary ponds and flooded areas. Males can be heard calling at night from the edge of, or from within the water. The species tolerates substantial habitat disturbance and no significant threats have been identified.[1]References1. ^1 2 {{cite journal | authors = Aquino, L., Kwet, A., Reichle, S., Silvano, D., Scott, N., Lavilla, E. & di Tada, I. | title = Odontophrynus americanus | journal = IUCN Red List of Threatened Species | volume= 2010 | page = e.T57186A11583471 | year = 2010 | doi = 10.2305/IUCN.UK.2010-2.RLTS.T57186A11583471.en }} {{Commons category}}{{Taxonbar|from=Q2238385}}{{Amphibian-stub}}2. ^{{cite web |url=http://research.amnh.org/vz/herpetology/amphibia/Amphibia/Anura/Odontophrynidae/Odontophrynus/Odontophrynus-americanus |title=Odontophrynus americanus (Duméril and Bibron, 1841) |author=Frost, Darrel R. |year=2016 |work=Amphibian Species of the World: an Online Reference.
