An extinct mammal from North Africa, related to elephants and dating from the Eocene epoch, known for its distinctive paired horns.
From Greek Arsinoe (Egyptian queen) + thēr (beast). The genus was named by paleontologists to honor the Egyptian queen while describing a prehistoric mammal.
Arsinoitherium looked absolutely bizarre—a hippo-sized mammal with two massive paired horns like a rhinoceros but weighing as much as an elephant—and it's so different from modern animals that scientists call it a 'living fossil' of its time.
