Explore the fascinating world of polar ecosystems from over 100 million years ago in this 59-minute lecture from the University of Melbourne's Science Festival 2021. Discover the types of forests and animals, including dinosaurs, that inhabited Victoria during the Cretaceous period. Learn about the Rift Valley, plant fossils, and the diverse fauna of the time. Delve into the environmental conditions, research methods, and evidence used to reconstruct these ancient ecosystems. Examine primitive fruits, ginkgo trees, and the effects of anoxia. Investigate temperature changes, carbon dioxide levels, and the emergence of ants. Gain insights into Australian fauna, rapid transitions in ecosystems, and the use of histology in paleontological research. Uncover the mysteries of ancient marsupials and the evolution of pine trees in this comprehensive journey through Cretaceous polar life.

The course spoke about the Cretaceous polar life, the plan was enriched, we spoke about the rifting stage of the oceanic opening of plate tectonics. of the faunal and floristic evolution, of herbivorous and carnivorous dinosaurs. of the evolution of mammals and birds.
The doctor also spoke about the environment and the living environment of the fauna. we saw the evidence of the extinction of dinosaurs in the Cretaceous (fusion of quartz, traces of iridiome, the canyon of Yucatan (meteorites fall ...), geophysical methods).
