London gets very festive this time of year and the dinosaurs at the Natural History Museum are getting involved.
The animatronic T-Rex at the museum is wearing a giant Christmas jumper and a very large Santa hat.
The designers used recycled materials to make the jumper which fits him perfectly.
Zips make it easier for staff to get him dressed.
The jumper has dinosaurs on it, with red hats so it resembles T-Rex himself.
Sam Barnes explains the importance of the jumper.
The dinosaur Christmas jumper is available to buy in the museum shop, in all sizes.
What's more, there are dinosaur socks, scarves and hats.
The seasonal jerseys are fun, but also serve an important role.
Every year it works with researchers around the world to publish more than 700 scientific research papers.
The research requires funds to continue and the jumpers and festive clothing will hopefully help the museum learn more about our natural history.
The design of the festive jumpers changes every year.
Who knows which exhibit will be chosen next year.
