This bird-like/dinosaur-like skeleton was found in a Western US cave in 2006. It was about a half mile into the cave within a very small crawlspace opening. They had some cans and bottles with them that they put out and proceeded to take photos. There was no way they were leaving the cave with this item. It had mineralized, part of the trachea was there and very brittle, some hide on it appears to still be on it. The finders did not really understand what they had found, but shared it with someone who recognized it was very unusual, MK Davis. MK was kind enough to share this with me to put out there for the public to puzzle over and see if anyone can identify what this was.
It was a large - what at the time looked like an ostrich sitting on its haunches, head missing, tail missing, upper arms missing and lower part of the hind leg articulation is missing....This is one of those mysteries that we hope to settle and I would seriously appreciate any input into what this was... Thank you Jim Heater, host of Paranormal Geeks Radio, for cleaning up the pics with this clearer version above.
A thank you to Bruce Hoch, who mentioned the lower legs and skull might have been taken by a shaman or tribe member long ago as trophies for the skull and claws or for powerful symbols. Very good. Keep the theories coming --
From the size of the discarded can in the background, the body section would seem to be at least a yard long from the base of the neck to the tail. Thunderbird skeletons are indeed allegedly discovered from time to time, I can think of at least three such alleged discoveries from Sanderson's files that come to mind. But this is the first allegation that comes with any backup documentation.
The fact that you cannot see any wishbone either bothers me. Perhaps it was also removed. We could tell if the bird could fly or not if we had the wishbone.
It would seem that MK Davis is keeping the location of the cave a secret but it is a safe bet it is in the central Rocky Mountain area generally, possibly just North or South of that.
