For replying Professor Chen, the writer sorts out some data to give reasons of that the ‘Qinghezhen Fauna’ and ‘Changtu Fauna’ are undoubtedly fossils.1. The fossils of the two faunas are obtained from the rock samples by acid treatment and have been directly discoveried in some rock samples, thin sections of rocks and on the residual samples of acid treatment. Those fossils are the same in characters.2. In total samples with acid treatment, there are samples less than one quarter producing the fossils and the recurrences of the fossil species are different in number.3. The analysis of chemical and mineral composition of the fossils with electron prob spectrograph and XRD show that the chemical composition is predominantly Caand the mineral composition is predominantly the minerals containing Ca2CO3. Comparison with the small shalls from southern Shaanxi the compositions of the samplesfrom northeastern China and southern Shaanxi are all predominantly Ca, but in addition, a lot of P in the samples of southern Shaanxi, suggesting the different geological setting in early Cambrian of the two places.The above facts lead the writer to believe that the fossils of the two faunas are really not pseudofossils but true fossils.
