The Dakota Group refers to a geological formation that is primarily composed of sedimentary rocks and is widely recognized for its extensive fossil records. This group is named after the Dakota City in Nebraska, USA, where the rocks were initially studied and described. The Dakota Group is known to span across various regions in North America, including parts of the United States, particularly in the midwestern and central areas, as well as parts of Canada.
Geologically, the Dakota Group is classified as part of the Cretaceous period, specifically the Late Early Cretaceous, dating back roughly 100 to 115 million years ago. It is often found underlying or immediately following the older Dakota Formation. The rocks within the Dakota Group are characterized by their fine-grained nature, indicating deposition in a predominantly terrestrial environment, primarily floodplain and delta systems.
The Dakota Group has proven to be a significant source of paleontological evidence, providing invaluable information regarding the flora and fauna of the Cretaceous period. Fossils found within these rocks include a diverse range of plant material, such as pollen and spores, as well as vertebrate remains, including dinosaurs, turtles, and crocodiles. These fossils have contributed greatly to our understanding of the ecosystems and biodiversity during the time of the dinosaurs.
In summary, the Dakota Group is a geological formation consisting of sedimentary rocks from the Cretaceous period. It is renowned for its rich fossil content, shedding light on the ancient ecosystems and organisms that inhabited the Earth millions of years ago.
