Thalassocnus natans was found in the Pisco Formation in what is now Peru. It lived during the late Miocene (~6 mya). Other Thalassocnus fossils have been discovered in Chile that date to ~7.6 mya (Late Miocene) and the morphology suggests that these specimens might belong to T. natans (Canto et al. 2008).
