Underprints

“Brontosaur bulges." Mid-way through the picture we can observe four bulges in a sandstone layer, depressing downward the underlying layers. These have been interpreted as a dinosaur trackway viewed in cross-section. A large sauropod left these “underprints" by deforming soft sediment while walking. Very specific conditions (e.g, sediment cohesiveness, rate of sedimentation, exposure vs submergence) are necessary for the preservation of footprints in the rock record. Scale bar is 40 cm long. Photo taken at Dinosaur Ridge, Golden, Colorado.
