Fullerenes in the fossil of dinosaur egg
- 化学化工－已发表论文 
By means of laser desorption post-ionization time-of flight mass specrometry (TOF) and high-pressure liquid chromatography (HPLC), fullerene C-60 have been found in a fossil of dinosaur egg shell from Xixia (N-33.3 E-111.4), China. These techniques verified also that fullerene C-70 is virtually absent fi om identical egg fossil of dinosaur at XiXia. Preliminary results suggest that C-60 occurrence and C-70 absence may be the outcome of environment (ambient temperature, and SO2 pollution of Earth's atmosphere, etc.) effects during the synthesis of fullerenes at 70 million years ago.
