'To hold a fossil in your hand is to be offered the gift of time travel and a clue to the mysteries of life.“ This quote, attributed to ”TT“, is stitched into a sampler near the entrance to Seaton Jurassic,which opens its doors for the first time on Saturday 26 March.
Ever since Unesco awarded World Heritage Site status to this 95-mile stretch of East Devon and Dorset coast, different places have competed to be its “Gateway”. Exmouth, at the extreme western – and oldest – end, has the Geoneedle where you can play Jurassic hopscotch, while Lyme Regis, the youngest section, has ammonites galore scattered tantalisingly along its shore. The eastern end is marked by Old Harry Rocks, starkly white chalk sea stacks, and the much-photographed natural arch of Durdle Door.
Throughout the coast's length are visitor centres and museums explaining the geology and proudly displaying their fossils. The most impressive of all, the skull of a pliosaur, “the world's biggest bite”, is in the Dorset County Museum in Dorchester. It's nearly two and-a-half metres long, which gives a clue to the reptile's full size: around 18 metres. Probably our most fearsome marine predator ever, its four powerful flippers allowed it to speed through the water in pursuit of prey some 155 million years ago.
One thing you'll learn from the many interpretation boards is that the Jurassic Coast is all about colour: notably, red, white and blue(ish). The cliffs reveal their age at a glance. Red is Triassic, mind-numbingly old at 250 million years, when southern England was a tropical desert close to the equator and part of the super-continent of Pangaea. This era gave way to Jurassic, as tectonic plates collided and Pangaea started to break up. Devon and Dorset slipped beneath the ocean and marine reptiles rapidly evolved in a world very much to their liking with plenty to eat, including each other. When they died their bones fossilised in the blue-grey mud and silt. Finally the Cretaceous era, 145 million years ago, brought us the white chalk cliffs consisting of millions of tiny sea creatures, heaved up and tilted by ever-advancing tectonic plates. Until: bang! A meteor hit Earth, calling time on dinosaurs and the Cretaceous.
The Jurassic Coast displays the most complete record anywhere in the world of the 185 million years of the Earth's history that we call the Mesozoic era. So, back to Seaton. This is the only town along the coast where you can see all three Mesozoic components in one place. Look west, and the chalk cliffs of Beer (Cretaceous) reflect their whiteness in the sea; then slabs of interloping red Triassic provide a backdrop to the beach; and finally there's some grey Jurassic by the Undercliff and the Great Bindon landslide which plays a major role in the new Seaton Jurassic centre. Forget dinosaurs; the centre celebrates and explains the story of life, in an imaginative and fascinating way. It's the prehistoric marine and flying reptiles that left their remains in this region, and the Bindon landslide of Christmas Day 1839 put Seaton at the centre of geological research and discovery.
TT, the author of the fossil quote, is Time Traveller, who guides the visitor through the new centre. There’s no solemn explanation of the wonders of the natural world, but interactive displays. There are drawers and books to open, buttons to press, knobs to twiddle. You can even row TT's time machine and view the marine world outside the portholes. At the end of Cretaceous there is nothing but water and sand. That's what mass extinction looks like.
Are you as strong as a starfish? Squeeze this handle and find out. Or as clever as a cuttlefish? Dress in a camouflage cloak and see. Would you be predator or prey if shrunk to the size of a limpet? Put it to the test. The Timeline Corridor leads from the first building blocks of life itself, a billion years ago, to homo sapiens, and explains some of the subtleties of evolution. Look at the skeleton of a dolphin compared with an ichthyosaur: one a mammal, one a reptile, millions of years apart, but so similar. That's convergent evolution. And look at a human arm and a dolphin's flipper: same bones, different size and uses: divergent evolution.
Come soon, before the crowds catch on, and, if you bring children, be warned. Afterwards they will want to show off their new knowledge exhaustingly. As might you, come to that.

The Jurassic Coaster bus runs from Exeter to Poole once a day (bit.ly/JurassicCoaster).
Seaton Jurassic (01297 300 390; seatonjurassic.org). Open daily 10am-5pm, admission £8 adults, £5 children, valid for a year. Lyme Regis Museum (01297 443370; lymeregismuseum.co.uk) and Charmouth Heritage Coast Centre (01297 560772; charmouth.org) have fossil displays and hold fossil walks.
The Fairwater Head Hotel provides comfortable accommodation in a country house with access to all the Jurassic Coast (01297 678 349; fair waterheadhotel.co.uk). Doubles from £104 including breakfast.
