The saurials were pretty significant in 2E Forgotten Realms. There were four races: finheads (hadrosaurs), hornheads (ceratopsians), bladebacks (stegosaurs), and fliers (pterosaurs), all Neutral Good, brought to the Realms from some far-off world by the evil (and now dead) god of filth, Moander, and liberated by the new demigod, Finder Wyvernspur.
They were converted to 3.0 as PC races in an issue of Dragon Magazine a couple of years ago, and WotC eventually put the article on their site for free. It shouldn't be too hard to find them there.
