A quick search for 'Dinosaurs' using Wikipedia and, a brief read through the information yielded the following bits of 'knowledge'... Dinosaurs were the dominant vertebrate animal of Terrestrial ecosystems for >160 million yrs., from the late Triassic period (approx. 230 million yrs. ago) until the end of the Cretaceous period (65 million yrs ago) when most of them became extinct or, so we have been led to believe.
