Matt Sewell's follow-up to the mega-hit Dinosaurs is a beautifully-illustrated large format look at the amazing beasts that time forgot - from the relatively well known, such as the sabre-toothed tiger and woolly mammoth, to the obscure monsters that walked the earth millions of years ago - many now forgotten. New findings are being made every year, and research is showing us exactly how these beasts looked and how they lived.

Creatures illustrated and described include:

• Sabre tooth tigers and woolly mammoths
• Glyptodon - an armadillo as big as a VW Beetle car
• Megalodon - a monster 60 foot (18m) shark
• Water King penguin - a red and grey penguin the size of a man
• Ornimegalonyx - a huge Cuban flightless owl, the largest owl that ever existed, at over 3 feet (1m) tall
• Indricotherium - looking like a cross between a huge giraffe and a rhino, the largest land mammal ever to exist. Adults were 20 tons in weight and over 25 feet (8m) tall
• Deinotherium - a strange-looking and huge, elephant-like creature with tusks positioned on its lower jaw and curved, facing downwards
• Short-nosed bear - a massive fearsome bear that kept North America human free
• Aurochs - the wild bull, striped and with huge horns
• Megatherium - the giant sloth, as large as a modern elephant
• Mastodons - related to the mammoths but with shorter legs and a longer body The giant otter, that weighed 35lb (18kg)

Less celebrated than the dinosaurs, the range of beasts is equally impressive, every one a scary, amazing creature that actually stalked the planet.

Like the dinosaurs, these beasts are awe-inspiring in their variety, with amazing details not seen on animals today and in a wide variety of furs, feathers and colours, making for a stunning collection of illustrations.
