The cliff in front of you dates back to the Cretaceous period in the Mesozoic era.
- Precambrian: the most ancient time in Earth’s history: from its formation 4.5 billion years ago up to 542 Ma (million years ago). The life forms were mostly unicellular bacteria.
- Paleozoic era (542 to 251 Ma): appearance of the first marine animals and then vertebrates. The continents began to be conquered first by plant life and then by animals.
- Mesozoic era, (251 to 66 Ma): arrival of big reptiles and dinosaurs. The first mammals, flowering plants and birds also evolved.
- Cenozoic era (66 Ma to today): proliferation and diversification of mammals (including Man!) and flowering plants.
