Cant imagine a taxidermist sitting down and making this. It appears to be made from the skin of a goat, cut and stitched together. I do not know what the underlayment is, but the hooves have what looks like wrapping on them, with a resin on top, as though the whole skeleton was made by hand.
The horns have the same wrapping as the hooves, they are not plastic. It stands over 16" tall, and is 17" long. Look closely at the pictures.
