"This igneous rock formed as ongoing volcanic activity covered the area with lava. Absolute dating shows this igneous rock ranges from 50 million to 47 million years old. Over time, those lava flows solidified into the rock we see today, and subsequent layers of sedimentary rock have accumulated above it. The presence of fossils within the overlying sedimentary layers indicates that life began to thrive in this region millions of years after the volcanic activity ceased, providing valuable insight into the geological history and the evolution of life in this area."
