📖 描述 🖌️
四不像或稱四不像鹿尾巴似馬而非馬、蹄子似牛而非牛、角似鹿而非鹿、頸子似駱駝而非駱駝,因此取了名字叫四不像。角形態比一般鹿角特殊、複雜,角部沒有明顯的眉叉,角幹離頭部一小段之後,分成前後2枝,前枝斜向上伸延,再分成前後2根等長的分枝。在腹面常出現不規則的凸節。通常會再分枝一次,角部顯著;前枝會再分枝,長而直,向後伸延且不再分枝,若再分枝也只有幾個小叉而已。

四不像鹿角和其他種類的鹿角最明顯的差別就是表面有突出的疣狀顆粒。

這一個四不像鹿角 表面清晰可見成排的縱向骨質化血管溝痕,這是鹿角生長期血管留下的壓跡;其粗壯的鈍角轉折,正是四不像基部特有的分叉結構。最精采的是頂部斷面,外層緻密骨包裹著內部極為發達的網狀海綿骨結構,這是無可爭辯的哺乳動物骨骼證據。

其次,顏色亦透露了埋藏密碼。這一標本呈現深褐與焦糖色,並伴隨大面積墨黑,代表它曾長期埋藏於富含鐵、錳元素的還原環境(如古代河湖或沼澤泥炭層)中。

這件化石石化徹底、紋理清晰,完美記錄了冰河時期的古生態。
