They dominated the Earth for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous period (65 million years ago).

Yes. Between around 230million years ago and 65million years ago dinosaurs (more than 1000 different species discovered) were the dominant terrestrial vertebrates.
