幻龙属目前已有约12个已命名种。模式种是N. mirabilis,化石发现于德国的壳灰岩阶(Muschelkalk,欧洲地层单元,相当于安尼西阶到拉丁尼阶)地层,是在1834年由德国古动物学家Georg zu Münster所叙述、命名。同样在1834年,Georg zu Münster命名了Paranothosaurus,化石发现于德国奥斯纳布吕克县,目前被改归类于幻龙属的一个种,巨型幻龙(N. giganteus)[2]。N. juvenilis的化石也发现于德国[3]。N. edingerae的化石发现于壳灰岩阶上层与考依波阶(Keuper,欧洲地层单元,相当于拉丁尼阶到瑞替阶)[4]。
N. jagisteus的化石发现于德国荷亨洛赫县的壳灰岩阶上层[5]。荷兰温特斯韦克更发现3种幻龙的化石,地质年代属于壳灰岩阶下层,包含:N. marchicus[6]、N. winterswijkensis[6]、温特斯韦克幻龙(N. winkelhorsti)[7]。N. cymatosauroides的化石则发现于西班牙的壳灰岩阶地层[8]。
