Pachyrhinosaurus. The mystery of the horned dinosaur / Пахиринозавр. Тайна рогатого динозавра

The hard layer of rock followed the cliff top, then stopped. Jim McCabe was dismayed. If the rock ended, the layer of fossils beneath it probably ended as well, and much of the work he and Darren Tanke had done would be for nothing. It was June 1986. McCabe and Tanke were science technicians from the Royal Tyrrell Museum of Palaeontology, in Drumheller, Alberta. Their mission here, high on a bank above Pipestone Creek, a 12-hour drive northwest of Drumheller, was to dig through dirt, mud, and rock to a layer of dinosaur bones. What they found would determine whether the museum explored the site further. 
McCabe and Tanke knew where to find the fossils. A 12-centimetre-thick layer of bones striped the bank, 10 metres above the creek. The fossils were part of a bonebed, a jumbled collection of many animals’ remains. <...>
