Dental wear variation and implications for diet: An example from Eocene perissodactyls (Mammalia)

Palaeotherium medium is sampled in the late Eocene at La Débruge, and separate British range data place regional Palaeotherium loss near the Grande Coupure without dating a global extinction instant.

The profile uses Palaeotherium at genus rank within Palaeotheriidae, while ecological detail is explicitly restricted to the sampled species P. medium.

In the sampled Palaeotherium medium, molar wear facets, high occlusal relief and mixed sharp and rounded cusps provide the morphological basis for dietary inference; limb proportions are not claimed here.

The La Débruge Palaeotherium medium sample is consistent with leaf browsing plus a smaller fruit or abrasive-seed component; habitat and locomotor behavior are not inferred from tooth wear alone.

This profile represents western European study records from La Débruge and the Hampshire Basin rather than a complete genus-wide occurrence distribution.
