A museum grows by the animal, adding each new specimen to the stack in the cabinet drawer. The latest, perched at the top, push the older ones down like tweets; in this way dinosaur bones are found deep inside the earth. Accumulating, their bodies feather the collection until the building can grow another wing. Generations pile up to be prepared, to be labeled and described. The features of their bodies mean that everything can change. Beaks grow, claws shrink. A perfectly round egg is laid, but what hatches from it is an IMAX theater.
