摘要
目的是观察杨氏中国尖齿兽有无筛板骨，探讨Ｘ线ＣＴ在古生物学研究中的应用价值。方法：选择扫描参数用传统ＣＴ、高档ＣＴ及工业ＣＴ分别对杨氏中国尖齿兽头骨化石标本进行扫描。结果：杨氏中国尖齿兽脑腔、鼻腔之间存在筛板骨，高档及工业ＣＳ能清晰显示筛板结构。结论：Ｘ线ＣＴ是无创性观察化石内部结构的方法，在古生物学研究方法中占据重要位置。
Objective: To observe whether the presence of the cribriform plate in Sinoconodon and conform the application of X-ray CT in paleontology Methods: To scan the Sinoconodon with medical X-rayCT (traditional and modern) and industrial X-ray CT. Results: There has cribriform plate between the braincavity and the nose cavity of the fossil and the bone can be observed clearly by the modem medical CT andindustrial CT. Conclusion: X-ray CT is a non-destructive technique for visualization the features in thefossils and can play a important role in Paleontology
