article_snippet.sent: But now a new theory is set to re-write the history books after the examination of more than 23,500 mammoth bones found more than 23,500 mammoth bones riddled with osteoporosis and lacking in calcium.
article_snippet.sent: Dr Leshchinsky, the head of the laboratory of Mesozoic and Cenozoic continental eco-systems, said: 'In some collections that we examined almost 100 per cent of more than 23,500 mammoth bones (pictured) had signs of osteoporosis' The major mineral deficiency - which came from the impact of rising temperatures on soil and water - resulted in more than 23,500 mammoth bones breaking more than 23,500 mammoth bones limbs and spines, and left more than 23,500 mammoth bones unable to walk.
article_snippet.sent: Dr Sergey Leshchinsky spent a decade analysing bone and teeth samples from mammoths that roamed western Europe and Russia between 10,000 and 30,000 years ago.
article_snippet.sent: Shown is a young mammoth jaw riddled with bone disease.

article_snippet.sent: Experts spent a decade analysing bone and teeth samples from mammoths ('graveyard' pictured)  that roamed western Europe and Russia between 10,000 and 30,000 years ago .
article_snippet.sent: Dr Leshchinsky, who wrote about his findings in the Archaeological and Anthropological Sciences journal, added: 'The articular surfaces of the limb bones in some specimens were not just damaged, some specimens were mutilated with disease. '
article_snippet.sent: The palaeontologist said that in The palaeontologist opinion the cause of the deaths was a metabolic disorder caused by mineral starvation.
article_snippet.sent: The palaeontologist is thought that mammoths did try to make up for mammoths calcium shortfall by eating clay on the waterfronts or in mud baths, but it was not in sufficient quantities to strengthen bones.
