A zoo in the US has appealed to the public to try and identify a mysterious creature which popped up on their security footage.

The strange creature was discovered around 1.25 am on May 21 outside a perimeter fence at the Amarillo Zoo in Texas.

“Was it a person with a strange hat who likes to walk at night? A large coyote on its hind legs? A Chupacabra? It is a mystery – for Amarillo to help solve,” the City of Amarillo said in a press release.

“It is important to note that this entity was outside the Amarillo Zoo. There were no signs of attempted entry into the zoo. No animals or individuals were harmed. There were no signs of criminal activity or vandalism,” City of Amarillo Director of Parks and Recreation Michael Kashuba said in the release.
