Here's what usually happens: "You'd take all the bones apart, and all the bones go in individual cases," Kenneth Lacovara, a Drexel University paleontologist, says. Researchers can easily build made-to-measure plywood cases for the bone pieces, cushioning the fossils with foam. "We use packing peanuts. We use foam that is meant for home insulation," Lacovara says. "Sometimes we use the foam that you'll see in, like, expensive camera cases." What foam he and his lab members use depends on the size of the bone, he says.
