I've been keeping an eye out for a stegosaurus plates for a while and I came across this guy. From some of the pictures it looks like a piece of neck armor. The shape and size seems about right but it's hard to tell if the base and tip are the right width ratios. Additionally looking at it zoomed in I'm not really seeing blood vessels and it looks more like a piece of sand stone so I'm not convinced it's real but I've been lurking on the site for a while and want to get some advice from others what they thought before paying the price
