This spring, history and prehistory collide in spectacular fashion as Patagotitan mayorum, one of the largest animals ever to roam the planet, arrives at Peterborough Cathedral.
From 13 April to 31 May 2026, visitors will be able to stand beneath the colossal skeleton of this titanosaur inside one of England’s most awe-inspiring historic buildings. The exhibition, presented in partnership with the Natural History Museum, marks the giant dinosaur’s first appearance outside London in the UK.
It promises to be a truly unforgettable encounter across deep time.
Meet Patagotitan: The Giant of Patagonia
Patagotitan belongs to a group of dinosaurs known as titanosaurs, long-necked plant-eating sauropods that dominated the Earth during the Early Cretaceous Period around 101 million years ago.
Its sheer scale is almost beyond comprehension.
- Length: Around 37 metres, longer than nine London fire engines lined up
- Height: Roughly 8 metres tall from ground to head
- Weight: An estimated 57 tonnes, heavier than nine African elephants
- Diet: Plants, stripped from trees with peg-like teeth
- Movement: Four immense pillar-like legs supporting its vast body
Even its thigh bone measures 2.38 metres, taller than most adults.
Photographs simply don’t capture the true magnitude of a dinosaur like this. Seeing the skeleton in person delivers a powerful reminder of the astonishing diversity of life that has existed on Earth.
A Discovery by Chance
The story of Patagotitan began unexpectedly in 2010, when a ranch worker in Patagonia, Argentina noticed a massive fossil bone protruding from the ground at La Flecha Ranch.
What followed was one of the most significant dinosaur discoveries in recent decades.
Between 2012 and 2015, palaeontologists excavated the site and uncovered around 280 fossil bones, belonging to at least six individual dinosaurs. The animals had been buried by ancient flood deposits millions of years ago, preserving their remains in extraordinary detail.
Because the fossils are so complete, scientists have been able to calculate the dinosaur’s size with remarkable accuracy.
The name Patagotitan mayorum reflects its origins:
- Patago – referencing Patagonia
- Titan – highlighting its enormous size
- mayorum – honouring the Mayo family who owned the ranch
From Grapefruit-Sized Egg to Giant Titan
Perhaps the most astonishing fact about titanosaurs is how small they began life.
Despite growing into animals weighing tens of tonnes, their eggs were only about the size of a grapefruit.
Fossil evidence suggests young titanosaurs grew at an extraordinary rate. In just two months, hatchlings may have increased to ten times their birth weight—a survival strategy in a prehistoric world filled with predators.
A Dinosaur Beneath Cathedral Stone
Seeing Patagotitan inside Peterborough Cathedral will create a breathtaking visual contrast.
The cathedral itself is constructed from Barnack limestone, a Jurassic stone rich with tiny fossil fragments from ancient marine life. In other words, the building already carries echoes of deep geological time within its walls.
Now, beneath its soaring Romanesque arches, visitors will encounter a creature that once wandered prehistoric forests.
The moment you stand beneath the skeleton, stretching dramatically across the nave, it becomes easier to imagine the living animal towering above ancient landscapes, calmly stripping leaves from tall trees.
A Moment of Awe for All Ages
Dinosaurs have fascinated generations since the word itself was first coined in the nineteenth century. But few experiences compare to seeing one on this scale.
Patagotitan transforms science into something immediate and tangible.
It is a moment of wonder that reminds us our planet has hosted worlds vastly different from our own—and creatures far larger than anything alive today.
For families, dinosaur enthusiasts and curious explorers alike, this exhibition is set to become one of the most exciting cultural events in Peterborough this year.
