In a luminous top-floor workshop closed to the public at the American Museum of Natural History in New York, artists work with scientists to re-create scenes from lost or vanishing worlds. This is the birthing room for the museum’s elaborate dioramas, such as the brace of Northwest Indians who air-paddle their canoe through a fluorescent entrance hallway, or the 94-foot blue whale that swoops down from the duplex ceiling of the Ocean Life Hall, or the herd of elephants with fearsome tusks and windblown ears that charges through the Hall of African Mammals.
In recent months, artists in the workshop have been putting finishing touches on a special exhibit called Fighting Dinosaurs. In a diorama for the new exhibit a fierce Velociraptor, looking like a thinned-down turkey with frighteningly large teeth, stalks a Protoceratops. With a flanged crest and beaked mouth that make it look like a goat-sized version of its larger and more famous cousin, Triceratops, the Protoceratops sees the predator coming and snarls. The scene is so vivid that some visitors may glance around nervously to be certain they haven’t been whisked back 80 million years by a hidden time machine. “When you come upon a diorama,” says David Harvey, the museum’s vice president of exhibitions, “it transcends all of the data. It becomes a real experience.”
Yet it is precisely that experience with which a growing number of scientists have a big problem: There is precious little data about dinosaurs to transcend. What the museum scientists know about Indians, whales, and elephants is more than enough to mimic real life. But when it comes to dinosaurs, all they really have to work with is an incomplete jumble of bones. Indeed, if the exhibits department were limited to just skeletal data for its dioramas and reconstructions, these halls would take on a most unromantic flavor. For instance, the Indians in the canoe would lack noses, ears, and breasts, and the
