重脚兽科(Arsinoitheriidae)是已灭绝重脚目下的一类哺乳动物。牠们的化石中东非洲亚洲罗马尼亚发现。重脚兽科的外表像犀牛,但是牠们却与犀牛并不怎么接近,反而与蹄兔目索齿兽目更为接近。

化石纪录

重脚兽科首先于始新世中期出现,土耳其原始的Palaeomasia也是在该时期出现。[1]重脚兽科下最后存在的重脚兽属,牠们首先于始新世末的法扬出现,并于渐新世早期与其他埃及重脚科一同灭绝Crivadiatherium是在罗马尼亚特兰西瓦尼亚发现,当地是雷兽出没最西边的地方。

命名

重脚兽科的学名是为纪念埃及托勒密二世的皇后阿尔西诺伊二世而取的,因为最初的重脚兽化石是在其宫殿的废墟附近发现。
