Five million years ago, Southern California likely featured a diverse environment characterized by a mix of coastal and inland ecosystems. The region may have included lush forests, grasslands, and wetlands, with a warmer climate than today. Fossils from this era suggest the presence of various prehistoric animals, including ancient marine life and terrestrial mammals, indicating a rich biodiversity. Additionally, tectonic activity would have shaped the landscape, leading to the formation of mountains and valleys.
