A bizarre video has emerged of a man having a bath while dressed in an oversized T-Rex costume.

The footage, captured at a home in California, USA last month, shows the dinosaur thrashing around in the bathtub for a while then sinking down for a relaxing soak.

The video is part of a series documenting the fictional life of a Jurassic Park exhibit.

"This video was made as it's tough working in Jurassic Park and it's nice to come back to a soothing tub," the filmer wrote online.

"I did this video since the bath bomb featured is a dinosaur and is 10 pounds!"

"Having a big body in a small tub leads to lots of problems and helps educate the world about T-rex problems," he added.
