Beyond existing photos of aliens which are usually at best of a mysterious provenance, actual alien remains, either in original or fossilized form, have surfaced from time to time..
The Roswell aliens are perhaps the most famous, although unconfirmed alien corpses found on earth. The Kyshtym Dwarf, nicknamed Alyshenko (top left) is another noted cadaver of an alien, reportedly found prior to its death by Tamara Prosvirina in the village of Kaolinovy in the Urals. Alyshenko was a highly diminutive alien of about a foot tall who was briefly sustained by its adoptive parent. The alien was found after Prosvirina was arrested. It was autopsied and as is usually the case with alien remains and data, lost from public scrutiny.
Most physical manifestations of alien presence on earth have been purely of human creation, produced by agents of popular culture for entertainment and commerce. The small alien in a jar at bottom left used in a film is such an example These specimens seem to represent an amalgam of images of other alien remains and photographs that have come to light over the years.
Alien remains are similar to alien photographs in that they seem to defy scrutiny even in their physical presence. While alien photographs beg for the presence of the blurry characters they contain, once their bodies are actually recovered, there are few, if any, additional discoveries to be made. These creatures tend to be extremely small and fetal-like in appearance. As newborn babies often defy easy gender identification, so do these " baby" aliens appear to be androgynous. Perhaps larger, more mature versions (if any are ever discovered) would reveal sexual characteristics. In the meantime, however, alien remains are doubly genderless in their infant-like development and in their perceived superhuman origins.
