古风野牛（学名：Bison antiquus）是1万年前更新世晚期时北美洲最普遍的大型草食性动物，且是现存美洲野牛的直接祖先^[3]。

描述

西伯利亚野牛于更新世冰河时期（大约 240,000 至 220,000 年前）^[4]^[5]^[6]从西伯利亚迁徙至阿拉斯加。西伯利亚野牛于300万年前在北美洲发展成长角野牛。约距今2万2千年前，长角野牛被古风野牛所取代。古风野牛于1万8千年前开始大量繁殖，并于1万年前与其他更新世大型动物群一同灭绝^[5]，而在这之后美洲野牛出现，直到现今^[7]。古风野牛在拉布雷亚沥青坑中是最为普遍的草食性动物^[3]。

对比现今的美洲野牛属，古风野牛体型较高，骨头及角较大。体型上较现存的美洲野牛大上 15-25% ，肩高可达 2.27米（7.4英尺），体长可达 4.6米（15英尺），体重则可达 1,588千克（3,501英磅）^[8]。古风野牛双角角尖之间的距离约为 1米（3.3英尺）。
