Reptilicus

Danish miners Svend Viltorft dig up a section of a giant reptile's tail from the frozen grounds in Sápmi (area), where they are drilling. The section is flown to the Denmark's Aquarium in Copenhagen, where it is preserved in a cold room for scientific study. But due to careless mishandling, the room is left open and the section begins to thaw, only for scientists to find that it is starting to regenerate.
