The Badlands looked vastly different millions of years ago than it does today. Layers of sediment would have been visible as well as ash from nearby volcanic eruptions.
The Paleolithic Age, also known as the Old Stone Age, spanned from about 2.6 million years ago to around 10,000 years ago. It is characterized by the use of stone tools and the growth of early human societies.
Artifacts can date back thousands to millions of years, depending on the material and preservation conditions. The oldest known artifacts, such as stone tools and cave paintings, date back to millions of years ago.
Yes, the Ice Age came before the Stone Age. The Ice Age happened millions of years ago, while the Stone Age followed afterwards, around 2.6 million years ago.
The Alps mountain range has been present for tens of millions of years. The formation of the Alps began during the Tertiary period, around 65 million years ago, through the collision of the Eurasian and African tectonic plates. Over millions of years, the mountains have undergone various geological processes, including uplift and erosion, to reach their current state.
Millions of years ago, when these rocks formed, it is likely that the environment was very different from the present. It could have been a marine environment with shallow seas, indicating the presence of marine organisms. Alternatively, it could have been a terrestrial environment with rivers, lakes, or forests, suggesting the presence of land-dwelling organisms. The specific characteristics of the rocks can provide further insight into the environmental conditions at that time.
Formation of the South Dakota Badlands, or White River Badlands, began about 69 million years ago when sediments from the great sea were deposited across what is now the Great Plains. Significant erosion of the badlands began about .5 million years ago and continues today.
