Fullerenes in the Fossil of Dinosaur Egg

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 mat fullerene C 70 is virtually abse...

Description
Summary: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 mat fullerene C 70 is virtually absent from 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 SO 2 pollution of Earth's atmosphere, etc.) effects during the synthesis of fullerenes at 70 million years ago.
