The Government body responsible for maintaining the nation's historic monuments has been forced to withdraw a children's guide to Stonehenge because it was littered with factual errors.
The book, called The Ghastly Book Of Stonehenge, has become a laughing stock among archaeologists because of its many blunders.
English Heritage, which receives £129million a year in Government funding, has recalled 4,500 copies of the £3 book and now plans to pulp them.
A spokeswoman said last night that an 'incorrect proof' – an earlier, unedited version of the book – had been sent to the printers.
The schoolboy errors include a passage in which the Bronze Age was mistakenly placed before the Stone Age, and an Ice Age mammoth was used to illustrate a chart showing Iron Age to medieval times.
Mammoths finally became extinct around 1700BC – almost 1,000 years before the Iron Age began in Britain.
An entry about 5th Century king Aurelius Ambrosius – believed to be the historical basis for King Arthur – mistakenly called him Aureole Ambrosias, a spelling error that appears to have been copied from the internet.
One paragraph states that Bronze Age bluestones, which archaeologists believe were transported to the site in Wiltshire from Wales, arrived in around 2550BC, while 'about 200 to 300 years' later, 'New Stone Age people added some much bigger stones'.
Grammatical errors are also rife, including examples such as 'Prehistoric carvings of daggers and axes on the stones is discovered by a photographer'.
