Dive back in time to meet the fiercest marine reptiles ever to swim the oceans, from giant ichthyosaurs to plesiosaurs, in this immersive deep-sea exhibition.
On the way in you get a small pamphlet, and each information station along the route has an embossing stamp for a different sea monster. Time Out's critic admitted the idea is as old as time and said it was still really fun.
The show covers the marine reptiles of the dinosaur era: ichthyosaurs with their strange eye sockets, long-necked plesiosaurs, marine crocodiles and the mosasaur, billed as the T. rex of the sea. The fossils get bigger as you go and end with a complete plesiosaur. In between are short films and a lot to touch, including a real mosasaur tooth and some fossil poo. It's the only place in South Kensington where touching poo is encouraged.
Time Out gave it four stars and called it more consistently entertaining than the 2023 Titanosaur show, though with less screen-based interaction and a smaller finale. The Museum says most people spend 40 minutes to an hour inside, and recommends it for ages 8 and up.
The full plesiosaur
The last and largest fossil in the show; look closely for bite marks where sharks fed on the body after it died.
A real mosasaur tooth
You can touch it, and it's almost 70 million years old.
The megalodon film
One of several short films on the ancient oceans, and the one Time Out singled out as particularly horrifying.
Leedsichthys
A giant filter-feeding fish the size of a whale shark, one of a dozen or so species most visitors won't have heard of.
The scaly fish hide
A replica of a Jurassic fish's skin that you can run your hand over; Time Out's pick of the touch objects.
