Appendix 3Microfossils Identified from Mesozoic mudstones by Guangdong Institute of GeologicalSciences (GIGS)HK 9314, 09276 10860, Kan Nga Ling (GIGS)Cibotiumspora sp.Cicatricosisporites sp.Cyathidites mesozoicus (Theirgar) PotonieDeltoidospora sp.D. irregularis PflugGranulatisporites sp.Lycopodiumsporites sp.Lygodiumsporites subsimplex BolchovitinaLophotriletes sp.Neoraistrickia sp.Pterisisporites sp.Reticulatisporites changningensis BaiToroisporis sp.Laricoidites ? sp.Pinuspollenites sp.Piceaepollenites sp.Miospores dominate the organic residue recovered from this sample. Significant numbers ofReticulatisporites changningensis, Lycopodiumsporites subsimplex, Cyathidites mesozoicus,Deltoidospora and Lophotriletes sp., Granulatisporites sp., Cibotiumspora sp. and othersindicate a Mesozoic age in South China.Age : Jurassic.HK 9329,10320 12245, Lantau Peak (GIGS)Classopollis sp.C. annulatus (Verbitskaja) LiC. parcus (Brenner) Xu & ZhangCerebropollenites sp.Psophosphaera sp.Psophosphaera minor (Verb.)

Classopollisannulatus and Psophosphaera minor dominate the sample and indicate the Late Jurassic,Age: Late Jurassic.164
