I did an Internet search on, "skeleton dragon," to see just what I could find. I was surprised at just how many exist, currently, on the market! They have a wide price range, and quality for gamers, varies, as well.
Here are some links to what I found:
1. 36" Dragon Skeleton Halloween Decoration, $62.98 USD, from Oriental Trading. Large, but the details are seriously lacking for its size.
2. Crazy Bonez Large Skeleton Dragon (Draco-Lich #1), $24.99 USD, on Amazon. It is 24" W x 16" L x 10" T. It is available in a few color schemes, beside bond: gold, and Oil Slick (multi-color black), but these are also slightly smaller in size.
3. 2+ foot Dragon Skeleton, $95.99 USD, on TMP link This thing lacks detail, but it is h-u-g-e, standing 27.2" T! Too big, really, even for an Ancient Great Wyrm, in 2e AD&D rules.
4. Ashland 13"; Dragon Skeleton (Draco-Lich 2.0), $16.78 USD, on Amazon; also available at Michaels. It is 11.81" L x 13.2" W x 5.31" T.
5. Gothic Dragon Skeleton Statue, $46.90 USD, on Amazon. It is 5" x 7.5" x 7", with some remnants of skin stretched between its wing ribs; its neck also appears to be covered in flesh, as it is much more than neck vertebrae; the skull also appears to have flesh covering most of it. This one could be painted up in any desired color, with plenty of flesh still attached to it, in the front, at least.
6. Crazy Bonez Light Up Skeleton Gargoyle, $14.99 USD, on Amazon. It is 7 x 10 x 9.5 inches, with blue LED eyes that light up.
7. Animated Majestic Dragon Skeleton, $59.99 USD, on Halloween Costumes. It is 36" L by 10" W by 27" T. Activated by sound: red eyes flash, jaw moves up/down; poseable.
8. Dragon Skeleton, 7.5", $6.99 USD, at At Home. This is 4.0" L x 7.5" H x 7.5" W. It's jaw is fixed, not moveable; it has molded flesh covering each wing, but it is otherwise just bone.
9. Halloween Dragon Skeleton, $129.99 USD, at Wal-Mart. Size: 49" long from snout to tail tip and 36" high from wing tip to foot. Low in detail, big. Very big.
Let's compare all of these to a legitimate, Pathfinder gaming miniature: Pathfinder Battles Deep Cuts – Gargantuan Skeletal Dragon, $32.00 USD, on Amazon.
If you read the customer reviews of the Pathfinder Draco-Lich model, you will see that many complain about it being too brittle! Many have had it break, requiring a glue job, to repair. Note that the non-gaming figures listed above, are all made of plastic. The three I have looked at, and handled, were all made of some durable plastic -- breaking them would require some effort! Dropping them three feet, onto a concrete floor, is not likely to break them! Also, I find the sculpting of the plastic Halloween decorations to be better, in many cases than the Pathfinder gaming model.
Prices are all over the map! Here is a Google Search for Skeleton Dragon, showing gaming miniatures, as well as many examples, posted above, with really different prices being offered! It pays to shop around. Cheers!
