Many of Scotland's native species are at risk of extinction, according to a new report.

Experts say one in 11 of our flora and fauna could die out if more is not done to conserve nature.

There have been thousands of species which once flourished in our climate, which are no longer roaming around.

The horrifying looking Arthropleura grew up to two metres long and apparently moved quickly across the forest floor in Caledonian forests.

Tracks have been found in Arran showing the speed at which it moved, and recent research shows that it was a herbivore.

Arthropleura became extinct at the end of the Carboniferous period, when the moist climate began drying out, destroying its rainforest habitat.

You are probably very lucky not to have been alive in the time of the cave lion.

They are thought to have been 25% bigger than current species of lion, and fed mostly on reindeer (another former Scottish native) and occasionally bear cubs.

The Hibbertopterus was a giant sea scorpion which was capable of moving on land.

They mostly inhabited freshwater swamps and rivers, feeding by raking through the soft sediment with attached blades to capture small invertebrates.

So basically they were over a metre-long, with attached blades and could move in and out of the water.

It's lucky they have been extinct for millions of years then.

If you wanted to see a woolly rhinoceros and were fortunate to have cheated evolutionary science so you were alive 27,000 years ago, then Bishopbriggs was apparently the place to be.

Evidence for its existence in the area has been found in the form of a metacarpal bone, tibia, humerus and molar tooth.

The species lived across Europe and northern Asia, and can be found in early cave paintings.

The grey wolf still exists in many places across the world, but were hunted from existence in the UK.

According to local folklore, Sir Ewen Cameron of Lochiel shot the last wild-living British wolf in 1680 in a Perth town, but records exist mentioning the species until the late 18th century.

Some wildlife campaigners want to reintroduce wolves back into Scotland to keep deer numbers down in the process of 're-wilding''.

Brown bears are still in Scotland, but are contained to imported specimens captivity.

It is believed they became extinct in Britain as a result of intensive hunting.

They are extremely fast, having been recorded at speeds of around 30 miles per hour.

The woolly mammoth is perhaps the best known extinct animal.

The emomous beasts were up to four metres tall and weighed around 8 tons. Much is known about the species due to the preservation of carcasses found in Siberian permafrost.

They were known to roam Scotland, and tusk section from a 46,000-year old was found near Kilmarnock.
