CIVIL WAR-ERA DINOSAURS?

These two photos apparently show Union soldiers standing over the corpses of an unknown species of giant bird. The upper photo is reputed to be of the so-called "Thunderbird" of American Indian myth, while the lower photo has been tentatively identified to show some form of pterosaur. Unfortunately, little is known about when or where these pictures where taken or what happened to the corpses.

The image below was taken sometime in the late 19th Century. It too shows a form of pterosaur, apparently killed on a ranch in Texas. However, as with many photos of this nature, the exact details are unknown.
