A mysterious “alien-like” creature with four limbs and a “reptile” skull has washed up on a beach in Australia.

Queensland man Alex Tan was stunned to come across the remains while walking on Maroochydore Beach on the Sunshine Coast, about 63 miles north of Brisbane, earlier this week.

He said he came across creature not long after floods hit the area.

“I’ve stumbled across something weird,” he said to the camera in an Instagram post. “This is like one of those things you see when people claim they’ve found aliens.’

The as yet unidentified creature has four limbs, a reptile-like skull and a tail.

People responding to Mr Tan’s post suggested the remains might be those of a baby kangaroo or a wallabe.
