| Abstract: | 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 |
