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。
The purpose is to observe whether there is a sieve bone in the Chinese jagged beast of Yang, and to explore the value of X-ray computed tomography in paleontological research. Methods: Scanning parameters were selected by using traditional CT, high-grade CT and industrial CT respectively. Results: Young Chinese sharp tooth animal brain, nasal bone plate between the existence of high-grade and industrial CS can clearly show the structure of the sieve. Conclusion: X-ray computed tomography is a non-invasive method to observe the internal structure of fossils and occupies an important position in paleontological research.
