最近自然杂志(Nature,432:383—386,2004)发表了Chengetal.的文章,首次报道了胡氏贵州龙的生育模式、性双形和可能胎生的证据,这无疑是非常重要的,但认为产胡氏贵州龙的竹杆坡组的时代为中三叠世,这与近年来牙形刺的研究结果不符。牙形刺的研究已充分证明竹杆坡组的时代为晚三叠世的早期(卡尼期)(王成源等,1998;Chen&Wang,2002),比以前认为的时代要晚出现大约一千万年。
The recent article by Nature (432: 383-386, 2004) published in Chengetal. Is the first to report on the fertility pattern, sexual bisexuality and possible viviparous evidence of the Guizhou Huzhou dragon, which is undoubtedly important, The age of the Zhupanpo Formation of the Guizhou dragon in Guizhou Province is Middle Triassic, which is inconsistent with the findings of conodont in recent years. Studies of conodonts have well documented that the age of the Zhupanslope Formation was Early Late Triassic (Carney period) (Wang et al., 1998; Chen & Wang, 2002), about ten million years later than previously thought .
