很少科學家注意到上述物種,直到在70年代到80年代,加爾東重新檢驗稜齒龍類。在1973年,加爾東與詹姆斯·詹森(James A. Jensen)敘述了一個標本,該化石缺少頭部、手部、尾部,當時被歸類於雷克斯侏儒龍,而且可能在研究前受到損傷[19]。到了1977年,加爾東認為敏捷侏儒龍與雷克斯侏儒龍、新標本之間有極大差異,於是將雷克斯侏儒龍,獨立為雷克斯奧塞尼爾龍(Othnielia rex)[20]。這個1977年的研究,除了重要的橡樹龍分布於各大洲的研究以外,另外也將伴侶化石龍、纖細化石龍,歸類於雷克斯奧塞尼爾龍,並提出快速化石龍是個疑名[20]。而1990年新發現的德林克龍,一度被認為是奧塞尼爾龍的異名,使這個狀況更為複雜[7]。
