surripimus

Surripimus is a newly described genus of small, herbivorous mammals that lived during the late Miocene epoch in what is now the central Sahara region. The name derives from the Latin words “surripuere” meaning “to dig” and the suffix “–imus” indicating smallness, reflecting the animal’s burrowing habits and relatively diminutive size. Fossils attributed to Surripimus were first discovered in 2021 by a joint expedition of the University of Montpellier and the National Museum of Natural History in Paris, following satellite mapping of potential paleo habitats.

Morphological examination shows that Surripimus possessed robust forelimbs and shortened hind limbs, adaptations consistent with fossorial behavior. Dental analysis reveals a typical ridged enamel suited for grinding fibrous plant material, placing it within the clade of early hyracoids. Comparative studies against the contemporaneous genus Cuspidipus highlight distinct skull proportions and a unique enamel pattern, justifying its classification as a separate genus.

The discovery of Surripimus provides insight into the adaptive radiation of small mammals in arid environments during the Miocene, shedding light on migration corridors between the African continent and the Arabian Peninsula. Current research focuses on isotope analysis to reconstruct its diet and environmental preferences. Future work aims to extend the fossil record and clarify its phylogenetic relationships within the Hyracoidea.
