Dino Update

Family values: were dinosaurs the first social creatures? -
World History, World - The Independent: "The majority of dinosaurs were peaceful, plant-eating creatures that developed the Earth's first strong social communities.

Herds, packs and families of dinosaurs were commonplace. Many fossils have been found where groups of dinosaurs died together, such as the ones which sank in the quicksand off the Isle of Wight. In Alberta, Canada, a mass grave has been discovered containing at least 300 grazing dinosaurs of all ages and sizes. This herd was swept to death by a flash flood while trying to cross a deep river. In Montana, in the USA, an even bigger herd of about 10,000 dinosaurs has been discovered. These creatures were poisoned by volcanic gases and buried in ash. Their fossilised bones stretch out in a straight line for more than a mile."
