From the pyrolyzed product at 200℃ of Gephyrocapsa oceanica a group of C〓 dicycle terpenoids were firstly identified. They were highly instable and sensitive to temperature because they can only generate at 200℃ and segregate or transform at higher temperature. Therefore they can not only be an indicator of special temperature of organic matter originated from G. oceanica, but can be used to distinguish organic matter from G. oceanica before the hydrocarbon generation peak.
