A 4.5m-long mystery creature with fur and flippers has washed up on a UK beach, leaving locals stunned.
A video released by Pen News showed the badly decomposed carcass washed up on Merseyside Beach in Liverpool on Wednesday.
The man who discovered the dead creature told the Liverpool Echo it "stunk" and had four-foot-long (1.2m) bones sticking out of its body.
"[It looked] like a half whale that had eaten a horse whilst giving birth to a snake."
The man said the creature had an extra "thing" attached to it and guessed it might have been giving birth when it died.
After pictures were posted in the Ainsdale Community Group Facebook page, users began guessing what the creature could be.
One user said: "A woolly mammoth? yes I'm aware they're extinct but honestly what it looks like to me."
Another user joked: "2020 what a year, the aliens have arrived."
Majority of social media users said they thought it was a cow or horse.
Natural England senior advisor Stephen Ayliffe told The Sun the unidentified animal is likely to be a species of whale.
