Woman discovers ‘alien’ creature in backyard after hearing scream

A woman has posted images of what appears to be an ‘alien’ type creature online, sparking speculation of what exactly it is.

Photos of the slimy, pink looking creature were posted on Facebook by California woman Gianna Peponis.

‘I heard something scream at like 11.30 last night and went out on my side yard and found this thing.

‘It was dead when I found it… Share with your friends.’

Social media users were sent into a frenzy trying to work out if it was a partially developed animal fetus or… alien.

One user wrote it was ‘clearly an alien’ while another offered a more realistic explanation – “It’s half of a deer fetus which has been chewed on by scavengers/predators.”
