Paraceratherium may look totally alien at first, but look again! You'll notice the resemblance to its modern relative, the rhinoceros!

Ever since the extinction of the northern white rhino, people have wondered whether the same technology that revived Paraceratherium could be used for rhino conservation. Unfortunately, such an effort is wasted without diverse genetic material. Low genetic diversity is not so much of a problem for animals that can't be released, like ours... ... but a wild population of revived rhinos would suffer from a genetic bottleneck.

Although it lacks the large horns of keratin we expect from rhinos, the face of Paraceratherium still shares many features with them. Particularly noteworthy is that triangular upper lip, a prehensile structure that helps them manipulate their food.

While a rhinoceros' smile could be considered rather unpleasant, the teeth of Paraceratherium make its smile something to behold! Beneath that long upper lip are two sets of tusks that point at odd angles from each jaw, making them look like they seriously need a visit from the dentist.
