Britain's extinct giants

Ever wondered about the UK's ancient megafauna? Find out about the prehistoric giants that roamed Britain.

When you think of the British landscape, what wildlife springs to mind?


Badgers, foxes, deer and even wild ponies make their homes on this green island. But Britain hasn't always hosted the same inhabitants.


You might be surprised to learn that huge beasts – the kind more often associated with myths and legends – once roamed these fair isles. Back then, the UK looked very different indeed.


Read on to learn about some of the wonderful giants of Britain's past.


Why did giants roam Britain?


In prehistoric times, Britain's landscape was affected by several ice ages – the last of which ended around 10,000 years ago. This meant that, for many years at a time, the landscape was covered in ice or glaciers.


During periods of glacial retreat, woodland began to replace the ice sheets and eventually took hold, resulting in large areas of sparse forests – perfect for megafauna to thrive.


As the climate gradually warmed and became suitable for human habitation, the first people arrived, having migrated out of Africa and into Europe. These intrepid travellers would have been greeted by some giant – and rather scary – animals. 


Sadly, all of our megafauna are now extinct. We learn about these creatures through what they left behind in fossils and bones. We've even found a few deep-frozen examples that have been preserved for thousands of years – though not in Britain.


Scientists across the globe have helped paint a picture of the prehistoric landscape by studying these artefacts using methods such as radiocarbon dating.


We'll soon explore  why these ancient giants died out. But first, let's meet a few of them.


The giant short-faced hyena


Vastly different from the African spotted hyenas we see today, the giant short-faced hyena is just one of the varieties of Ice-Age hyenas that once lived in Britain.


It would have been a fearful sight for our Neanderthal and Homo Erectus ancestors, standing at one metre in height and weighing up to 240 pounds. That's nearly the size of a lioness. Eek!

Much larger than modern hyenas, the giant short-faced hyena was also known to prey on humans. Scary indeed.


The cave lion 


Would you believe Britain was home to the largest cat ever thought to have existed? Cave lion bones have been found in Torquay, so we know for a fact that they were here. (Enjoying a seaside holiday, perhaps.)


Beautiful but fearsome creatures, their coats were sandy and mottled and they could reach a whopping 800 pounds. Somehow, though, they could still run at around 30 miles an hour. Now that is a humongous and speedy cat!

Sabre-toothed cats 


Around the size of modern-day tigers and lions, sabre-toothed cats tended to live in plains and grasslands.


Using their environment to hide, the cats waited in ambush for their prey rather than chasing them down. They hunted animals like mammoths and bison, piercing their flesh with those large, sharp teeth.


The woolly mammoth


The poster child of prehistoric animals, the woolly mammoth is an iconic beast. To think, this elephantine ancestor used to roam the wilds of Britain. How amazing!


Mammoth remains found in Shropshire
suggest that mammoths may have lived here until about 14,000 years ago – not 21,000 as previously thought.


A relative of the African elephant, mammoths lived in a considerably colder environment, so their skin was covered in dense fur. They looked a bit like an elephant wearing a woolly jumper – hence the name.


The auroch


Aurochs were part of the Bovidae family of animals, which includes cloven-hoofed ruminants such as yak, cattle and goats.


All domestic cows are descended from ancient aurochs, which were once common across the globe. Just like modern cows, they were grazers in the grasslands of prehistoric Britain and their dung helped create highly fertile ground.

Rewilding scientists in Britain are currently researching the possibility of reintroducing aurochs to Britain, following a successful back breeding programme in Europe.
The woolly rhinoceros


This sizeable vegetarian is thought to have arrived in Britain around 300,000 years ago, having migrated from Europe across Doggerland. This sunken land mass used to stretch between Britain and France.


Just like Britain's mammoths, woolly rhinos were covered in fur, which allowed them to thrive in harsh conditions. Similar in size to their modern-day cousins, they are thought to have died out in Britain around 8,000 years ago. 


So, what happened to them all? 


Debate rages among the scientific community as to how and why our megafauna became extinct. 


Some think that the arrival of humans was the death knell for our megafauna, as we were able to hunt as a team with purpose-built tools such as spears.


Were we so successful at harvesting these beasts that they simply could not sustain their populations? Some argue that it's too simplistic to place the blame solely at our ancestors' feet. They argue that other factors, such as climate change and the knock-on effects on food availability and habitats, must also have played their parts.


Perhaps our arrival happened to coincide with other factors that were already placing stress on the megafauna. It may be that we just tipped the balance.
