在1920年,加拿大古生物學家威廉·狄勒·馬修(William Diller Matthew)將一個位在美國自然歷史博物館的頭骨與骨骸的照片,命名為原鵝龍(Procheneosaurus),該化石出土於加拿大亞伯達省的恐龍公園組,年代為上白堊紀的晚坎潘階[3]。原鵝龍的命名普遍不認為具有效性,而該標本後來被建立為Tetragonosaurus。但是,理查·史旺·納爾(Richard Swann Lull)反對Tetragonosaurus的用法,繼續使用原鵝龍。
P. convincens的化石是一個幾乎完整骨骼,只缺少口鼻部與尾巴末端,發現於哈薩克斯坦,年代為白堊紀晚期。該種是由蘇聯古生物學家羅特傑斯特文斯基(Anatoly Konstantinovich Rozhdestvensky)在1968年命名[8]。P. convincens可能是鹹海牙克煞龍(J. aralensis)的異名[9],也可能足以成立個別的屬[10]。
