In Depth

       Members of the genus Xenohystrix are prehistoric relatives of Hystrix cristata,‭ ‬also known as the crested porcupine which lives in Africa today.‭ ‬Like with their living relatives,‭ ‬Xenohystrix would be expected to have a covering of sharp quills to protect them from predators.‭ ‬Also like living porcupines,‭ ‬Xenohystrix may have eaten plants and occasionally invertebrates while also scavenging carrion from time to time.
