Discussions by Yann Oliver
Our vision of dinosaurs lifestyles has got through much change during the last decades. Dinosaurs are now considered to be active, terrestrial animals rather than half-asleep, semi-aquatic reptiles. They are now recognised to have been able of fast running, to have had efficient feeding capabilities, and some evolved social behaviour (see also the discussion about warm-bloodedness allowing sustained activity).
Moving discussing dinosaurs common postures, running capabilities, briskness...
Habitat . A summary of the discussions about the putative aquatic habitat of some dinosaurs (mainly sauropods and hadrosaurs), leading to the conclusion that they were probably terrestrial.
Feeding describing the adaptations of lots of dinosaur groups to particular and efficient ways of feeding, showing that dinosaurs did not eat soft, aquatic plants.
Behaviour showing social behaviour such as sexual displays, care to the young, structured herds, known from several dinosaurs.
