A 2022 Texas Journal of Science study by Wade E. Miller at Rancho Carabanchel, San Luis Potosí, produced remarkable findings. A charcoal sample tied to Equus mexicanus calibrated to AD 1025–1165 — nearly 500 years before Columbus. The site also preserved E. conversidens and E. tau remains.
Rancho Carabanchel fossil evidence extends horse survival to AD 1165
Key facts
- W.D. Miller and colleagues published a 2020 study 'Post-Pleistocene Horses from Mexico' in the Texas Journal of Science
- Site: Rancho Carabanchel in San Luis Potosí, Mexico
- Researchers conducted 19 radiocarbon determinations tied to fossil remains and stratigraphic units
- Identified Equus mexicanus, Equus conversidens, and E. tau in underlying units
- Calibrated horse-associated dates include ~1660-1508 BC, 1544-1424 BC, 548-400 BC, AD 73-226, AD 86-242, and AD 253-542
- Most extraordinary: a charcoal sample associated with Equus mexicanus produced calibrated date of approximately AD 1025-1165, nearly 500 years before Columbus and 300 years before Spanish arrival
- A mandible attributed to Equus mexicanus was recovered from the same stratigraphic layer as human lithic artifacts
