I would definitely agree with ratite tarsus (not foot exactly), but could be emu (as far as I can tell without checking).
My first thought was snake, because the broad scutes look like ventrals, but the other scales are not ophidian-like and such a combination occurs in no squamate of sufficient size. Non-overlapping polygonal scales are typical of archosaurs.
After reading John Scanlon’s post, and looking at some photos of boots (is that cheating?) I withdraw my snake vote and say it does truly look like ostrich leg.
Definitely not a caiman(or any other crocodilian) belly, which have multiple scutes per transverse row, nor a crocodilian’s tail, where the distalmost whorls do have one ventral, but the laterals are also enlarged. Lizards are out for the same reason– those with enlarged ventrals have multiple scales in each transverse row. Snakes have a single enlarged ventral, but the laterals look more irregular in size and arrangement than I would expect on most snakes. I have insufficient knowledge of ratite (ostrich, emu, etc.) feet to make an informed comment on that possibility.
That, in longer words, is the reasoning that was taking me towards a snake too.
But just to be different and split the difference, how about an axolotl? (Now having to check the size of axolotls … and their spelling! Typically 23, max 30cm ; doesn’t look likely.
OK, having considered scale scale, it’ll have to be a big snake : python, boa or anaconda? On which point … I hear my space ship (a Cobra Mk3, out of Lave on the Tionisla run) calling …
Oh yes, of course. I don’t get to see many amphibians – severe declines here over the last few decades – and I’d forgotten the silky smoothness of their skin.
Yep, it’s ostrich leg, as several people have noted (pat yourselves on the back!). The “scales” indicate to me the reptilian ancestry of birds, but perhaps they’re not homologous chracters. Some reader will know.
Thank you for another excellent post. Where else may anybody get that kind of information in such an ideal means of writing? I have a presentation subsequent week, and I’m at the look for such info.
Alligator tail.
/@
Handsome pair of boots! I would go with alligator tail also.
I’ll compromise with 1 and 2: Caiman tail?
Cayman.
Or, in Ferengi, “Cay-mon.”
Dragon. The windpipe.
Goat
Ostrich’s feet?
Desnes Diev
Yes, I think so too.
Wouldn’t it have two toes then?

Gila monster belly.
Lemme revise that to caiman tail.
Looks like the belly of a snake.
My thought, too, but obviously not….

The Welsh Three-toed Hopping Catfish? It’s definitely not axolotl this time…
I think ostrich leg skin.

Can’t be an axolotl– amphibians don’t have epidermal scales.
Oh yes, of course. I don’t get to see many amphibians – severe declines here over the last few decades – and I’d forgotten the silky smoothness of their skin.
Upon further reflection, I think it’s the big toe of a ratite. Can’t tell if it’s ostrich or emu.
Dungar DoraThen crafted those from the big toes on the front foot of the Black Dragon Giedromax, Terror of the southern Narlmarches.
Homo sapien – Feet
(Those boots can’t fool me!)
Some type of monitor lizard
*monitor lizard belly*
Ostrich legs!
It could also be giant turtle legs? 😉
Stingray tail.

They are homologues.
Here are some photos of ostrich legs and feet:

Too late to guess but must say they’re nice lookin’
