The sphenoid bone forms the rostral part of the base of the neurocranium and is composed of two segments, the presphenoid [os praesphenoidale] and the basisphenoid [os basisphenoidale]. Rarely studied in osteology, we tested whether it can provide distinctive features between domestic sheep (Ovis aries L., 1758) and goat (Capra hircus L., 1758). For this goal, we studied a sample comprised by 53 dry modern skulls of adult sheep (n = 36) and goat (n = 17) subjects from a modern comparative collection by means of geometric morphometric techniques using a total of 26 anatomical points (2 saggital landmarks and 24 semilandmarks). Results showed that form (size + shape) differences appear between both species: sphenoid among sheep tends to be bigger, longer and wider than in goats, differences of width being mainly located on basisphenoid width.
蝶骨构成颅神经基底的前部，由两个部分组成，前蝶骨 [praesphenoid 骨] 和基蝶骨 [basisphenoid 骨]。蝶骨在骨科学中很少被研究，我们测试它是否能为绵羊（Ovis aries L.，1758）和山羊（Capra hircus L.，1758）提供独特的特征。为此，我们使用几何形态测量技术，对来自现代比较收藏的 53 个成年绵羊（n=36）和山羊（n=17）的干燥现代头颅标本进行了研究，总共使用了 26 个解剖点（2 个矢状标志点和 24 个半标志点）。结果表明，两种物种之间存在形态（大小+形状）差异：绵羊的蝶骨比山羊的更大、更长、更宽，宽度的差异主要位于基蝶骨宽度上。
