Document Summary
Why research victorian dinosaurs: only diverse (more than 200 different species of plants and animals known as fossils) polar dinosaur assemblage in the world, represents an ecosystem that has no modern counterparts. Cool temperate assemblage that experiences long dark period but not continental glacial conditions. In rocks of the right age and type: early cretaceous rift related river sediments: along the coast of the otway ranges, along the cape paterson coast. Inland in both areas casterton area baraboolhills (geelong) morningtonpeninsula 38- Cretaceous location & environment: age: 115-110 million years ago, early cretaceous period (valanginianto early albian) Latitude: >70osouth = below the antarctic circle = dark for at least 3 months of the year in winter. Fauna: fish including lungfish and primitive bony fish (palaeoniscoids) that live beyond their time elsewhere in the world, amphibians - labyrinthodonts, which live several million years longer on the australian continent than elsewhere in the world.
