How many dinosaurs are there?

Answer 1

Approximately 700 species have been named so far, although recent research suggests that half of these have not been sufficently differentiated from existing species. Recent studies have estimated that there are still 700-900 more genera to be discovered, and many more species in the existing 540 genera.

As far as the number of dinosaurs as individuals, recent finds in Alberta indicate that the Centrosaurus and Styracosaurus travelled in herds of hundreds if not thousands. This makes dinosaur numbers like the numbers of wildebeast in the old African movies or buffalo on the North American plains.

Answer 2

There are over 1,000 different species of non-avian dinosaurs, over 9,000 species of avian dinosaurs, over 500 genera of non-aviandinosaurs, and nobody knows how many individual non-avianor individual avian dinosaurs there are.
