旋角牛
哺乳动物物种
旋角牛（学名：Pseudonovibos spiralis）是柬埔寨及越南的一种牛科动物，也是旋角牛属的唯一已知物种，由于实证不足，其真实性至今存疑。

特征
编辑名称
编辑旋角牛的柬埔寨名字“kting voar”最初被西方译为“丛林绵羊”，故被误会是一种与羊有关的动物。这个柬埔寨名字事实上是“角像藤一般的野牛”。由于混淆，越南曾有报告称它们在当地的为名字“羚羊”，但其实那是当地人对鬣羚的称呼。
旋角牛的学名“Pseudonovibos spiralis”并不有效，因为其完模标本其实是一只家牛，而此学名的字面意思正好是“有旋角的伪家牛”。
争议
编辑最初支持旋角牛存在的证据是沃尔夫冈·皮特（Wolfgang Peter）在胡志明市市场购来的一些角。[1] 皮特认为这些角属于一个新的物种。[2]
由于没有解剖资料，旋角牛的种系发生学地位不明。皮特等人建议将旋角牛分类到羚羊族中[1]，但从形态分析却指它们应属于牛族[3][4][5]，更有学者认为是羊族。[6]遗传学分析却造成了更混淆的结果。[7][8][9][10] 不过这些DNA明显是受到了污染。[11][12][13] 所有相信是属于旋角牛及用来进行DNA测试的标本，其实都是人工制成的家牛牛角。[12][14]
怀疑者都认为旋角牛只是传说的动物，但也有学者认为传说的本身可能代表着一种野生牛族的存在。[5][15] 若后者是真的，旋角牛应是十分濒危或甚至已经灭绝。
