April 20th 1890, Two ranchers were returning from a trip to the Huachuca mountains (about 38 miles south-west of Tombstone), when they discovered a huge winged monster resting on the desert between the Huachucas and the Whetstone mountains. The beast -- described as resembling an alligator with an extremely long tail and giant wings -- lifted into the air to escape, but was apparently exhausted when found and capable of making only short flights at the time. After the initial shock of the moment had passed the two ranchers, Winchester rifles in hand, rode after the fantastic critter. After chasing the monster for several miles as it presumably kept taking a series of short flights to escape them, the men finally had it in range and opened fire on the gigantic creature. It turned to attack, but "owing to its exhausted condition" was easily evaded by the men who kept shooting at the animal, which soon partly rolled over and became motionless.
The ranchers took time out to examine and measure their strange prize: from head to tail-tip it measured ninety-two feet, with a greatest diameter of about fifty inches. The animal only had two feet, a short distance in front of where the wings were attached to the body. The head alone was eight feet long, with jaws thickly set with straight, sharp teeth, and eyes the size of a dinner plate that protruded out of the head. The wingspan of the beast was an astounding 160 feet from wingtip-to-wingtip! The animal's body had no hair or feathers, just smooth skin which was easily penetrated by a bullet; the wings were nearly transparent membranes.
