Alien autopsy, Roswell, New Mexico, 17 July 1947 - This is actually a color foto of a Hollywood prop!
This body was observed to be in a state of significant deterioration. It had been preserved with formaldehyde solution but not otherwise dissected. Picture 2. The cadaver was 44 inches long with a weight of 27 pounds when the preservative solution had been drained.
The external appearance of this cadaver was of a human embryo with an enlarged hairless cranium. Hands and feet were normal. Finger and toenails had been pared. Fingerprints of a swirl-left pattern were observed and taken. All ten fingers and toes were apparent. There was some vestigial webbing between first and second fingers and toes.
Sexual organs appeared to be those of a male. They were in an embryonic state and revealed no evidence of pubescence. Ears were partially formed, and showed some evidence of surgical intervention. Folds of skin had been drawn out from the surface of the scalp in an apparent attempt to create the impression of a more fully developed ear than was actually present. Lips were vestigial and the mouth contained no erupted teeth. The nose was also in an incomplete state of growth and had also received surgical intervention, resulting in what appeared to be a very thin and delicate organ.
Eyes were distinguished by extensive surgical intervention. They were almond-shaped and by far the most prominent facial feature. The eyeballs were not matured and appeared to have been sutured with opaque artificial lenses of an unknown type. Because of their extremely unusual condition, dissection of these eyes was not attempted. Picture 1.
An incision was made from the thorax to the scrotum. The skin was first extended from the fascia and the fascia was observed to be consistent with the appearance of an immature human male. The fascia were then dissected and the internal organs were observed. The position of the heart was observed to be vertical, as would be consistent with a very early fetus, prior to the fourth month. The organ was prominent and was weighed to be 1/70th of the mass of the body. When the organ was dissected it was found that there was direct communication between the two auricles through the formen ovale. The Eustachian valve was observed to be large. A ductus arteriosus was observed to communicate between the pulmonary artery and the descending aorta. This ductus opened into the descending aorta just below the origin of the left subclavian artery. Picture 3.
Alterations in the structure of the circulatory system suggested that this body had been surgically corrected to detach it from placental dependence in an artificial manner. The stomach was opened and found to be free of any food substances. The cardiac orifice was apparently atrophied, although the deterioration of the corpus made this difficult to determine. It is possible that this individual did not eat.
The liver was prominent and it was clear that the blood of the umbilical vein would traverse it before entering the inferior cava. The umbilical vein itself had been severed of its placental crown and returned to the circulatory system by a means that was beyond the scope of this dissection to establish.
The lungs were not developed. There were lateral pouches on either side of the central diverticulum, open through into the pharynx. The larynx was somewhat cartilaginous and the trachea was developed. It is probable that this individual did not breathe. The means of sustaining life is unknown, if he was ever alive in any practical sense.
The cranium was dissected and it was found that the skull was formed of exceptionally thin and pliant cartilaginous material, appearing to be bone precursor that had been affected in some manner, making it more than usually thin and delicate. The brain itself was extensively and surprisingly formed. There was an unknown cortex superimposed on the forebrain and extending as far back as the fissure of Ralando. Because of this extraordinary formation it was decided not to pursue dissection of the brain at this time. The organ was extracted and placed in fluid preservation pending further study.
Overall, this corpus presented the appearance of a human embryo of three to four months duration that had been the subject of considerable alteration and modification, some of it obviously surgical. Other modifications, such as that of the brain, were harder to understand. In addition to the alterations, there was the matter of the size of the body and the relatively mature condition of the epidermis and nails. It would appear that this fetus was separated from its mother and brought to a semi-functional state by artificial means.
This is a human fetus that has been subjected to forced maturation without normal gestation. Its degree of functionality while living if it ever was alive is unknown.
