Dinosaurs existed during the Mesozoic era, from about 230 to about 65.5 million years ago (Late Triassic to Late Cretaceous). Their descendant taxon Aves (the birds) persists to this day, however.

Answer:
Dinosaurs lived on Earth for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous period (about 65 million years ago). At the end of the Cretaceous an extinction event caused the death of most dinosaur species. Only birds, which evolved from theropod dinosaurs during the Jurassic period, survived until the present day.
The dinosaurs didn't suddenly "appear" on the earth. Animals evolved over millions of years to the point where they took the forms we are familiar with now as dinosaurs. The fossil record is clear in this. Smaller, less sophisticated creatures gave way to larger and more complex critters. Some 230 million years ago is the general time that paleontologists consider the dinosaur first appeared. Things rolled along until about 65 million years ago when the lights went out for the dinosaurs.
A link to the Wikipedia article on the dinosaur is provided.
Dinosaurs first appeared during the Triassic period, around 280 MYA (Million Years Ago), and died out around 65.5 MYA. They evolved from Archosaurs, or "Ruling Reptiles". It is still unknown why they died out.
230-65 milllion years ago.

Never
The plants, insects, fish and dinosaurs lived on earth during the late Cenozoic era. Now all that is left on the earth are the fossils.
700,000,000,000 Years ago, after the Dinosaurs were killed by the asteroid.
Non avian dinosaurs appeared during the Carnian stage of the Triassic period about 220 million years ago. They diversified in the Jurassic and even more in the Cretaceous, but they died out 65.5 million years ago. All non avian dinosaurs lived during the Mesozoic era, but birds, which are a group of dinosaurs, continue to exist today.
I know that the angiosperms were most dominant during the cretaceous period but im not too sure about the dinosaurs dominant era. I would assume they were both dominant in the same era but I am not 100% sure.Read more: http://wiki.answers.com/Dinosaurs_and_angiosperms_were_dominant_lineages_during_with_geologic_era#ixzz1G5bqBpQR
During the Mesozoic era, dinosaurs, pterosaurs, and large marine reptiles diversified. Early mammals evolved. Eventually, flowering plants evolved. At the end, dinosaurs died out, leaving mammals to fill the many empty niches.

Paleozonic era
Dinosaurs and mammals coexisted during the Mesozoic era. If you count birds as dinosaurs, then they still coexist now in the Cenozoic.

100 types of dinosaurs lived during the mesozoic era.
Dinosaurs existed from 230 to 65.5 million years ago. That was from the mid Triassic period to the end of the Cretaceous period. All three periods were in the Mesozoic era.
The dinosaurs, those giant lizard creatures, dominated the face of Earth for about 165 million years. This period of time is called Mesozoic Era, and during this time the planet suffered several violent changes.
From about 230 million to 65 million years ago during the Mesozoic era.
After the dinosaurs died out came the era of mammals.
