Dull teeth, long skulls, specialized bites evolved in unrelated plant-eating dinosaurs
(PHYSorg.com Archaeology & Fossils)
 




Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn`t all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time and time again. An investigation of the skulls of 160 non-avian dinosaurs revealed the evolution of common traits in the skulls and teeth of plant-eating members of otherwise very different families of these extinct reptiles. These new examples of convergent evolution in plant-eating dinosaurs appear December 5 in the journal Current Biology.
