Document Summary

There is a close relationship between how the earth has changed and how dinosaurs evolved. Nigersaurus early cretaceous, africa teeth are all in the front, broad snout, very fragile thin struts specialized for low feeding with dental batteries. Much smaller at front of snout, highest rate of tooth replacement for dinosaurs; individuals got new teeth every 2 weeks: rebbachisaurids: bizarre, early late cretaceous diplodocoids of sa, africa and. Europe most are recently discovered: e. g. Malawisaurus elongated neck, small head, quadrupedal gate: titanosairia: very successful clade, only sauropods at the end of the cretaceous - wide heavy bodies and more flexible vertebral articulations some had. Futalognkosaurus: late cretaceous, sa the legs are apart: large range of body size: some titanosairia were relatively small sauropods and others were the largest that ever lived. Alamosaurus most are incompletely known but estimated to be 35m long and approx. 75 tonnes sizes are huge biggest terrestrial animals.
