The '''Balumtun Sandstone''' is a geologic formation in Chiapas, Mexico. The formation is up to 760 metres thick, and consists of gray sandstone, that were deposited during the Upper Aquitanian stage of the Early Miocene.<ref>{{Cite journal|last1=Carbot-Chanona|first1=Gerardo|last2=Rivera-Velázquez|first2=Gustavo|last3=Jiménez-Hidalgo|first3=Eduardo|last4=Reynoso|first4=Víctor Hugo|date=December 2020|title=The first Pan-Carettochelys turtle in the Neogene of the American continent and its paleobiogeographical relevance|url=https://linkinghub.elsevier.com/retrieve/pii/S0895981120304685|journal=Journal of South American Earth Sciences|language=en|volume=104|article-number=102925|doi=10.1016/j.jsames.2020.102925|bibcode=2020JSAES.10402925C |s2cid=224976641 |url-access=subscription}}</ref>
