    A number of Sydney’s old buildings have walls of sandstone blocks.Today, the Hawkesbury Sandstone is mainly used for ornamental purposes.So when fossils are found in sedimentary rock layers, they are identified within the context of where they fit in the evolutionary ‘tree of life’, and a millions-of-years ‘age’ is therefore assigned to the fossil and the rock accordingly.2 In recent years a variety of techniques have been developed to ‘date’ some rocks and minerals using the decay of radioactive elements in them.These methods include potassium-argon, rubidium-strontium, uranium-thorium-lead and samarium-neodymium dating.Because of its relative isolation over millennia, Australia has a rich, unique fossil record, dating from approximately 3.2 billion years ago, close to when the Earth was stabilising its formation.Since separation of the former continent Gondwana, an almost continuous record of the distant past is present in Australia today.Chemical fossils are the organic compounds and microscopic organisms that have left their mark in the rocks.

    Because of its hardness and durability, the Hawkesbury Sandstone not only provides a solid foundation for downtown Sydney’s skyscrapers, but is an excellent building material.They are used, for example, on layers of volcanic rocks above and below fossil-bearing sedimentary rock layers.Thus these methods, though not directly dating the fossils, have often ‘confirmed’ the millions of years ages assigned to the rocks and fossils by their interpretation within the uniformitarian and evolutionary framework.Sarah Taylor (Ph D Candidate, USyd): A Hydrogeochemical study of shallow saline groundwater in south west Sydney, Australia.
