This "creature" is what is known as a "gaff"(a Google search will bring up zillions of adds and sites advertising fishing gaffs, a long pole with a hook on the end for taking large fish out of the water by hooking through their lip or gills) I do not know where the term comes from.
Basically they are creatures that are created from all sorts of things including actual skeletons, skin, hair, fur, claws, teeth-and whatever else might be employed including modern materials such as silicone, latex and resins.
They have been created for all sorts of purposes including side shows at fairs, circuses and carnivals-some famous examples are the Fiji Mermaids and the Cardiff Man-also for movie props, publicity and promotions and to sell as curiosities-and of course to hoodwink the unwary as outright hoaxes.
Some artists can create what look to be authentic remains of bizzare animals-and only close scrutiny will reveal they are not what they seem to be.
One very common example here in the U.S. is the "jackalope"-a creature created by gluing the horns of the American pronghorn antelope onto the stuffed body of a common jackrabbit-both denizens of the Western US.
To someone who is not very savvy about animals it looks darn real-and some of these creations are so lifelike it is virtually impossible to tell they are not genuine remains of real creatures-and some of them are downright terrifying-check out these websites-one discusses the "fairy" issue and pretty much debunks the thing-and the other features a "chupacabra" carcass that looks so real and hideous it will give you nightmares.
