The Hawkesbury Sandstone is not 
more than 100 feet in thickness 
around Mt. Victoria. These 
sandstones are singularly desti- 
tute of organic remains. Good 
impression of Tliinnfeldia may 
be found at Mt. Piddington. 
The Narrabeen Shales will be 
readily recognised in the cut- 
tings on the Hartley-road. 
Glossopteris , Vertebraria, but no 
Marine fossils. Associated with 
the Kerosene Shale and fine- 
grained sediments with ripple- 
mark. 
The Coal occurring here, 2,900 
feet above sea level, is the 
same which proved by the 
Cremorne bore to lie 2,900 feet 
below Sydney. 
The Marine Beds of Bonnie Blink 
abound in fossils such as Pro - 
ckictus, Terebratula, A phanaia , 
Pecten, M odiola , Conocardiutn , 
Martinia, Euomphalus, Platy- 
schisma, Gonidaria, Stenopora, 
Fenestella , Protoretepora.
