A rare Jurassic crocodile (est. $70,000-90,000) is a formidable offering, as is the skeleton of a massive wooly rhinoceros of the last Ice Age (est. $70,000-90,000.) A giant prehistoric "Irish Elk" skull with antlers measuring five feet across the width (est. $30,000-35,000) represents the largest species of deer to have ever existed.
