探索恐龍化石的顯微世界

Open a Window for Investigating Jurassic Dinosaur Fossil by a Perspective View of Synchrotron

臺灣古生物研究團隊利用臺灣光源同步輻射紅外光譜顯微術及薄如蟬翼的化石試片製作技術透視侏儸紀祿豐龍的胚胎化石內部的成分及陸地上生物鏈頂端的肉食恐龍如霸王龍及鯊齒龍如牛排刀的尖鋸齒結構發展。依據二維紅外光譜影像及次其微米結構的結果，除了推翻化石內不可能保存有機物殘留物的推論之外，而且還提出肉食恐龍尖鋸齒結構形成的新概念。此研究獲得國際古生物界的重視，也將臺灣的古生物研究推向國際舞台。 Synchrotron-radiation-based infrared microspectroscopy and the technique of ultrathin sectioned fossil making in Taiwan Light Source open a new window of paleontology in unfolding mysterious Jurassic embryology and development of serrated teeth of carnivorous dinosaur. Taiwan paleontologists proved the paleontological possibility to reality of preservation of organic remain within 195 Myrs Lufengosaurus embryos, and proposed a novelty of serrated teeth development based on the investigations by using infrared microspectroscopy.
