舊鯊齒龍的正模標本(編號MB R 1938)是數節關節脫落的尾椎,位於尾椎中段。在正模標本的挖掘地點,另發現一節前段尾椎(編號MB R
1940)、兩節後段尾椎(編號MB R
2166),有可能跟正模標本都來自於同一個體。化石是在1909到1912年間發現於德屬東非(目前的坦尚尼亞)東南部,詳細地點是敦達古魯組(Tendaguru
Formation)地層的中恐龍段,地質年代約1億5400萬到1億5000萬年前,相當於侏羅紀晚期的晚啟莫里階到早提通階。舊鯊齒龍的標本,目前都存放在柏林自然科學博物館。在1925年,德國古生物學家沃納·詹尼斯(Werner
Janensch)將這些化石歸類於角鼻龍的一種(Ceratosaurus
roechlingi)[1]。由於缺乏可供鑑定特徵,這個種後來被視為疑名,只能確定屬於堅尾龍類。
命名與詞源[編輯]
在2011年,奧利佛·勞赫(Oliver
Rauhut)重新研究這些東非化石,並命名為新屬舊鯊齒龍(Veterupristisaurus)。模式種是米氏舊鯊齒龍(V.
milneri)。屬名意為「古老的鯊魚蜥蜴」,意指舊鯊齒龍是已知生存時代最早的鯊齒龍科恐龍;種名則是紀念古生物學家Angela C.
Milner[1]。
