Stenomylus

Stenomylus is an extinct genus of miniature camelid native to North America that is known from the Oligocene and Miocene epochs(23.1~16.3Ma). Its name is derived from the Greekστενός (stenós, "narrow") and μύλος (mýlos, "molar").

Stenomylus was extremely diminutive compared to other ancient and modern camelids, standing only 2 feet (61 cm) tall on average. It was a slender animal with a long neck, having some resemblance to a modern gazelle. Based on theories about its biomechanics, unlike modern camelids, Stenomylus lacked padding on its hooves.
