旋角牛學名Pseudonovibos spiralis)是柬埔寨越南的一種

特徵[编辑]

旋角牛最初被認為是像動物,有著一對長約45厘米及扭曲的角,身上有斑點。牠們一般會與拉上關係。

名稱[编辑]

旋角牛的柬埔寨名字最初被誤譯為「叢林草」,故被誤會是一種與有關的動物。這個柬埔寨名字事實上是「有像籐角的野牛。但是,其越南名字卻指牠們羚羊,產生了更多的混亂。

旋角牛的學名並不有效,因為其完模標本其實是一隻家牛。此學名的意思是「有旋角的偽家牛」。

爭議[编辑]

最初支持旋角牛存在的證據是沃爾夫岡·皮特(Wolfgang Peter)在胡志明市市場購來的一些角。[1] 皮特認為這些角屬於一個新的物種[2]

由於沒有解剖資料,旋角牛的種系發生學地位不明。皮特等人建議將旋角牛分類到羚羊族[1],但從形態分析卻指牠們應屬於牛族[3][4][5],更有學者認為是羊族[6]遺傳學分析卻造成了更混淆的結果。[7][8][9][10] 不過這些DNA明顯是受到了污染。[11][12][13] 所有相信是屬於旋角牛及用來進行DNA測試的標本,其實都是人工製成的家牛牛角。[12][14]

懷疑者都認為旋角牛只是傳說的動物,但也有學者認為傳說的本身可能代表著一種野生牛族的存在。[5][15] 若後者是真的,旋角牛應是十分瀕危或甚至已經滅絕
