This nifty little dragon fossil turned up in a twitter post while I was Googling for a halloween prop. Unfortunately, the post didn't include any information on who actually created it. Following up on the information in the specimen tag lead me to The Sorcerer's Library site. They helpfully identified James Brierly as the original sculptor. It was just one of an entire series of collectibles, but it appears the line died out just after the turn of the century.
