Sculpting "Specter of Howe Quarry"

in 2011 Mark was commissioned by a private collector in Colorado to create a 1:7 scale, polychromed bronze sculpture of Allosaurus fragilis. The concept was derived from a painting done for the Siber & Siber Museum, Switzerland, based on a Late Jurassic mass mortality event at the Howe Quarry,Colorado. Here many dozens of diplodocid sauropods died of dehydration and exposure after they congregated in an ever-dwindling waterhole, and were scavenged by the apex theropod predator.
