| Description: |
A natural cast of a hadrosaur footprint, lifted from the ceiling of a Cretaceous coal mine and bearing the trace of a single moment some seventy-five million years ago. The duck-billed maker, likely Prosaurolophus or a closely related hadrosaurine, pressed its broad padded sole into the saturated peat of a Western Interior swamp during the Campanian Stage of the Late Cretaceous. Before the spongy peat could rebound to its undisturbed state, an overbank flood deposited fine silt into the depression and sealed it. Across the long quiet of geological time the peat compressed into coal, the silt hardened into sandstone, and the footprint inverted itself, hanging downward as a sculptural protrusion from the strata above the seam. The Blackhawk Formation of east-central Utah and the Mesaverde Group of western Colorado yielded thousands of such casts during the active mining decades of the twentieth century, the great hadrosaur herds of North America writing their passage in negative.
Very good condition. Repaired with some small parts reattached. Losses and chipping in areas. Otherwise, nice presentation.
