TheColhuehuapian age is a period ofgeologic time (21.0–17.5Ma) within theEarly Miocene epoch of theNeogene, used more specifically within theSALMA classification in South America. It follows theDeseadan and precedes theSantacrucian age.^[1]

The age is named after theColhué Huapí Member of theSarmiento Formation in theGolfo San Jorge Basin,Patagonia,Argentina.
