Skeletons, from Kent.com
Human skulls with horns were discovered in a burial mound at Sayre, Bradford County, Pennsylvania, in the 1880's. Horny projections extended two inches above the eye-brows, and the skeletons were seven feet tall, but other than that were anatomically normal. It was estimated they were buried around AD 1200. Some of the bones were sent to the American Investigating Museum in Philadelphia, where they seem to have disappeared.
In 1837, a number of tiny human skeletons from 3 to 4 1/2 feet tall were found buried in tiny wooden coffins near Coshocton, Ohio. There were no artifacts found, but the number of graves led one observer to note that they "must have been tennents of a considerable city."
Seven skeletons were found in a burial mound near Clearwater Minnesota, in 1888. They had double rows of teeth in the upper and lower jaws and had been buried in a sitting position, facing the lake. The foreheads were unusually low and sloping, with prominent brows.
In 1911, miners began digging guano from a cave 22 miles southwest of Lovelock, Nevada. Soon, a mummy was found, a 6 1/2 foot tall person with "distinctly red" hair. According to the ancient legends of the local Paiute Indians, a tribe of red-haired giants, the Si-te-cahs, were once the mortal enemy of the indians in the area, who had joined forces to drive the redheads out. Measuring the femurs of some of the skeletons recovered, researches decided that they belonged to people between 6 and 10 feet tall. Others, however, have stated that the tallest is no more than 5'11, which is still considerable height for the time and place, but hardly a giant. Also, they point out, taking a black-haired mummy from a dark cave often causes the hair to turn red. It is unclear if this happened in Lovelock or not.
