Weaubleau eggs are a type of rock which only forms in the area around Weaubleau, Missouri. They are spherical nodules, composed primarily of chert nucleated around siltstone clasts from the Northview Formation.[1] These nodules have been found as far away as Newton County, Missouri, approximately 125 miles southwest of the impact area.
