DESCRIPTION:Non-avian dinosaurs are some of the most intensive
 ly studied of all extinct animals\, but the origin
  of the group remains contentious. The discoveries
  of dinosaur 'precursors' and early dinosaurs in A
 rgentina and Brazil have led to a consensus that d
 inosaurs originated in South America during the ea
 rly part of the Late Triassic\, around 235 million
  years ago. However\, this conclusion might be the
  result of biased sampling\, as few Middle and ear
 ly Late Triassic dinosaur sites are known from any
 where else. New study of historically collected sp
 ecimens and additional fieldwork in southern and e
 astern Africa are now starting to add more informa
 tion to this debate and have the potential to re-w
 rite the narrative on dinosaur origins. The pictur
 e currently emerging from South Africa\, Tanzania\
 , Zimbabwe and Zambia suggests that early dinosaur
 s and their ancestors were more geographically wid
 espread than recognised previously and the origin 
 of dinosaurs was rapid\, followed by a slow rise t
 o ecological dominance.
