How dinosaurs were born to be big: Their biology 'was skewed towards giant species'Palaeontologists had thought size distribution among dinosaurs was similar to modern animalsNew findings shed light on the differences in life in the age of the dinosaurs and now | UPDATED: 13:07 GMT, 21 December 2012 The biology of dinosaurs explains why there were more giant species among the prehistoric animals than are found among modern vertebrates, a paper published yesterday claims.
