Permian marine fossils (sourced from rocks some distance above here).
We leaned against the rocks at the bottom of the stair down from the end of Flinders Esplanade (north section) and Pat talked about the fossiliferous boulders that occur here. They are from the Permian sedimentary rocks in the hills above were deposited ( around 240-260 million years ago Mya))..
But the main rock sequence exposed here is much younger - a mere 40 million years, when earthquake tremors caused massive landslips deposits to accumulate south/eastward of the Taroona Fault line (positioned in line with the main road, above here).
Taroona, at this time ( 60-40 Mya) was a series of lagoons with plant life. Not marine but freshwater. Ancient turtle fossils were found very near here .
Observations:
All nestled in at the mouth of the creek (no name as yet) that disgorges onto Dixons Reef. The larger pebbles are all piled up like on a strand. On one hand washed down by the creek and on the other hand tumbled and thrown back by the sea. A few coast walkers came by looking over our shoulders to see what we were up to with our maps. To the south a clear example of the tilt of the sedimentary layers.
