A grim scene discovered behind a door in a kitchen during renovations of an old home has left thousands of people stunned after a photo was posted to social media.
A man from the US state of Michigan shared the photo to a Facebook page dedicated to mysterious discoveries on Monday, writing: "A friend of mine was remodelling her kitchen when she found this behind the pocket door".
The photo shows a pile of skeletal remains which were discovered behind a sliding door.
The man didn't provide any additional details, but many people speculated that the remains belonged to rodents or opossums.
The post got more than 4400 comments and shares before it was deleted.
Many people expressed their horror at the discovery and some were also disturbed by a huge collection of what appeared to be dead worms seen piled up at the base of the door.
"Someone put out rat poison and it got carried back to the nest where they all died. I’m guessing meal worms came to eat the dead rats, and some of them died from the poison too," one person speculated.
Others had more creative suggestions about what animals the skeletons had belonged to, with a man writing: "Scorpion skeletons".
Many had trouble deciding what they thought of the discovery, with one woman writing: "Soo sad and cool".
"Rad find but also really sad," another wrote.
Post sparks many questions about mystery remains
Another person presented an explanation behind the large prevalence of what seemed to be dried up worms.
"The 'mealworms' are actually larder beetle larvae casings. Museums will use larder beetles to clean carcasses, they can strip them down to clean bone very quickly if there are enough of them," they wrote in a comment.
Others were shocked the home occupants had been unaware of the decomposing matter, given its likely the rotten bodies emitted a stench at some stage of their deterioration.
It is not know if the house had been vacant for a long period of time.
"I can’t believe no one ever smelled the decomposition or wondered where the flies came from," one said.
"Can't imagine what that would've smelled like before they got to this stage," someone else wrote.
