About the stamp design: Stamp pictures artwork by James Gurney of Rhinebeck, New York (best known as the author and illustrator of the Dinotopia books).
First Day City: The World of Dinosaurs stamps were dedicated in a ceremony at the Museum of Western Colorado’s Dinosaur Valley Museum in Grand Junction, Colorado. Grand Junction is known as the “Dinosaur Triangle” of western Colorado and northeastern Utah. Many dinosaur fossils have been found in the area over the years.
Second Day Ceremony: The second-day ceremony was held on May 2nd at the Berger Dinosaur Hall of the Museum of the Rockies in Bozeman, Montana. Consultant Jack Horner was the main speaker. Horner’s famous long-time rival, Dr. Robert Bakker, had attended the first-day ceremony, making one wonder if, perhaps, Horner had decided not to attend in order to avoid him.
About the World of Dinosaurs set: Originally to be four stamps, Gurney was later asked to do eight designs, then 10, and finally 15. This was partially inspired by complaints USPS had received in the past about wasting paper on big souvenir sheets. Gurney arranged the dinosaurs in two panoramic shots, one representing the Jurassic Period (150 million years ago) and the other representing the Cretaceous (75 million years ago). The artist consulted with famous dinosaur expert Jack Horner as well as Michael Brett-Surman of the Smithsonian, Ken Carpenter of the Denver Museum of Natural History, and Phil Currie of the Royal Tyrell Museum of Paleontology in Alberta, Canada.
In addition to offering suggestions for less-common dinosaur species, Gurney said “The scientists also provided me with lots of information about other creatures that would have shared the world with dinosaurs: frogs, turtles, insects, crocodiles, pterosaurs, mammals, and birds – as well as the plants: sequoias, cycads, tree ferns, and horsetails… Recreating the full texture of this environment was very important to me. Too often, illustrations give the impression that dinosaurs just trotted around on dry lakebeds looking grumpy while a volcano chugged away in the background. In fact, their world was a rich and diverse ecosystem. There were plenty of plants and animals that looked a lot like what you would find today in Florida.”
History the stamp represents: Mounted in a Berlin museum is a Brachiosaurus skeleton measuring 80 feet long and 39 feet high. In life, the creature probably weighed 75 tons and was capable of holding its head 42 feet in the air. At one point, Brachiosaurus was thought to be the largest land animal that ever lived. But the discovery of a nine-foot-long shoulder blade bone suggests other dinosaurs, dubbed Ultra- and Supersaurus, attained lengths of over 100 feet and weights of 100 to 150 tons.
Brachiosaurus differed from other giant plant eaters in that its front legs were longer than its back legs, giving a head-to-tail slant to its backbone. Like a giraffe, Brachiosaurus sought food in high places. Food was plentiful during the Jurassic Period, a time when forests developed and spread. And this giant creature needed a lot of it – three or more tons a day.
Like other massive plant-eating dinosaurs, the Brachiosaurus lived in herds which roamed about, browsing on vegetation. Extremely slow moving, their main defense was their enormous size. And although an Allosaurus may have tried to size a stray young one or sick adult, it would never attack a healthy, full-grown Brachiosaurus.
