Why you should visit the West Coast Fossil Park

​By Roxanne Reid
Drive about 90 minutes north of Cape Town and you’ll find a strange place where giant creatures roamed long before the appearance of man on Earth. Here at this heritage site a fascinating journey has been quietly waiting more than five million years for you. Find out why you should visit the West Coast Fossil Park.

​Step back in time. This is the West Coast, but not as we know it. Gone are the Sandveld and the Mediterranean climate. In their place are lush subtropical forests, open grasslands and an estuary with lots of water.

Sivathere, a short-necked giraffe, and some of her buddies are trying to cross a river swollen with flood waters, convinced the grass is greener on the other side. It’s a mistake. Many of them get swept away by the current and drown.

But instead of being washed out to sea, their bodies become trapped by an outcrop of phosphate rock. You might think Sivathere is this story’s main character, but she’s not. The outcrop is – because if it didn’t trap the bodies here none of this story would be known today.

Hyenas and vultures have a field day, feasting on the flesh of Sivathere and her friends, and exposing the bones. Years pass. Sediment covers the bones and protects them from the elements. Over the next hundred years or so the sea level rises steadily and water floods the valley. The bones are buried deeper and deeper under layers of sand.

There they lie for millions of years, bone slowly turning to stone. And that’s how the West Coast Fossil Park’s story began. 

Mining uncovers the fossils
Fast forward five million years to 1976 when some of these buried fossils were uncovered during phosphate mining on the West Coast. Although mining stopped here in 1993 it’s thought that many tons of fossils were crushed up with rocks before anyone knew they were there. ‘Something like 80% of what there once was has probably been destroyed,’ guide Martina Mabuza told us. Since the phosphate rock was turned into fertiliser, you or your parents may have spread crushed five-million-year-old fossils on your lawn without knowing it.

Although about a million fossil specimens were collected and stored in the Iziko Museum in Cape Town, some of the larger bones have been left on site for visitors to marvel at. Iziko Museums and the mining company became partners to form the West Coast Fossil Park, which opened in 1998. Then in 2014 the entire 700ha was declared a National Heritage Site.

Tour a dig site
Martina took us on a short walk to a dig site protected from the elements by a shade-net dome. On the Anysberg hill nearby, Stone Age tools have been discovered, but our focus was to go back much earlier than the appearance of man in the area. Inside the dome, cables divide the site into one-metre squares. There are so many fossilised bones, it’s hard to believe they all ended up here naturally and haven’t just been collected for display.

​Palaeontologists have worked on a 10cm layer at a time. If it’s hard they add some water and wait for it to soften. It’s a painstaking process, digging with a trowel while being careful not to damage the fossil bone or tooth – both of which can tell palaeontologists a great deal – then using a paintbrush to carefully brush away the sand. Their toolbox even includes a small dental pick for fine work. Once the fossil is revealed, it has to be identified and catalogued.

Bones of a long-necked giraffe were also found here, as well as an animal related to the okapi that still occurs in the Democratic Republic of Congo where it moved when global warming changed the climate on the West Coast from subtropical to Mediterranean. In all, the bones of nearly 300 species of animals have been found in three different quarries.

In another section of the dig site, Martina drew our attention to the jawbone of a hippo and parts of a baleen whale and seal, showing how land-based mammals like sivatheres, freshwater mammals like hippos, and marine mammals were all buried together in this place.

The exhibition hall
When we first visited the West Coast Fossil Park a few years back, the visitor centre was rather cramped and dingy in what used to be the phosphate mine’s offices. In December 2017, a swish new visitor centre opened, with a museum, education centre and restaurant. Built using R67 million from the National Lotteries Commission, it stands on a rise overlooking the dig site where visitors can see for themselves the amazing number of fossilised bones.

​Part of the new visitor centre is an amphitheatre and exhibition hall that is stuffed with interesting information about the area from 37 million years ago until now. It tells the story of how sea levels changed and the subtropical climate and vegetation transformed to what we know of the West Coast today. The most interesting phase is around five million years ago, because that’s the period from which came most of the fossils at the dig site you see on your tour.

It makes you understand how much the environment has changed over the past 37 million years, and how important it is that we protect what we have now for the Earth’s future.

​Read about fascinating creatures that are now extinct, like the gomphothere (a kind of four-tusked elephant), giant pigs and predators like sabre-toothed cats and African bears. Unlike these large animals that are no longer with us, some micro-mammals like golden moles, elephant shrews and mice that were walking around this part of the world way back then have modern examples still living in the area today. 

​The huge central hall enjoys wonderful natural light from a skylight roof. In pride of place are wood sculptures of three enormous sivatheres, which are the most common large mammal fossils found at this site. The figures were sculpted by Egon Tania using found alien wood. They give visitors a three-dimensional sense of what sivatheres used to be like. 

There’s plenty room for more exhibits in the side passages and Martina hinted that now the Fossil Park has an appropriate space to show off fossils that were found here, they’re negotiating with the Iziko Museum in Cape Town to bring some of them back home.

In a sheltered courtyard outside the exhibition hall, enjoy the garden that has been created using plants similar to those that occurred here five million years ago. You’ll notice palm trees, cycads, and tree ferns in what used to be rich subtropical vegetation, which is very different from the scrubby fynbos we know today – all the result of a change of climate.

10 cool facts about West Coast fossils

• Fossils have proved that now-extinct animals used to live here, like sabre-toothed cats, short-necked giraffes (sivatheres), African bears and three-toed horses.
• Fossil bones discovered here vary in size, from the tiny the ear bones of a golden mole to the huge jawbone of a whale.
• The African bear stood 3m high when on its hind legs and weighed up to 750kg. Given that the grizzly bears of North America today are about 2m on their hind legs and weigh around 300kg, the African bear must have been pretty darn intimidating. In fact, it was probably the biggest land-based carnivore in southern Africa in the last 15 million years.

​Things to do at West Coast Fossil Park
1. Take a guided fossil tour to an actual dig site to see bones of the short-necked giraffe and other animals where they have been uncovered. It’s a fascinating insight into a place that holds the keys to unlock the deep history of the West Coast. You can book online.

2. Don’t miss a visit to the Pliocene Garden and the exhibition hall, which is packed with fascinating facts about prehistoric times and the fossils found here.
3. Hire a mountain bike (or bring your own) to enjoy one of the four mtb trails at the site. Choose from 3km, 5km, 8km and 10km, depending on your staying power.
4. Go on one of four walking trails to see some birds and plants and to enjoy the views towards Saldanha and Vredenburg. The trails are beautiful in August and September when the spring flowers are in bloom.
5. Book ahead with the educational centre for kids or students to take up a trowel and paintbrush at a mock dig, where they can have fun learning what it’s like to be a palaeontologist. On our first visit to the Fossil Park, we watched young tourism students really enjoying this hands-on part of their experience.

6. Enjoy coffee or lunch at the restaurant, either indoors or under umbrellas on the deck. You’ll find dishes like toasted sarmies, burgers and gatsbys on the menu. Specials of the day may include quiches and wraps and of course there are always sweet treats like lemon meringue pie and carrot cake. Let the kids play on the jungle gym outside the restaurant to enjoy the fresh West Coast air.
7. If you’re a keen birder, book a guided walk with a bird boffin for a chance to see and photograph typical West Coast species.
8. Visit the shop at the visitor centre to pick out a memento to take away with you, from T-shirts and scarves to toiletries, mugs and books.
