Saurial

The Saurials are a race of humanoid dinosaurs from Dungeons & Dragons. Although published with statistics in the Forgotten Realms setting, their game-lore actually depicts them as hailing from another world entirely, as they had been brought to Toril by the malevolent deity Moander to serve as its slaves. This ploy was foiled, and the surviving Saurials have attempted to make a new home for themselves in the Lost Vale, where they were initially held prisoner.

Saurials were first introduced as part of the "Finder's Stone Trilogy" novels, and subsequently received racial writeups in both the Complete Book of Humanoids (Advanced Dungeons & Dragons) and in Dragon Magazine #292, as well as appearing in monstrous write-up for AD&D in the Monstrous Compendium Forgotten Realms Appendix II and the Monstrous Compendium Annual III.

Saurials apparently come in many varieties, but because only four varieties made it to Faerun, we only know of these; Finheads (hadrosaurid), Bladeback (stegasaurid), Flyer (pteranodon), and Hornhead (ceratopsian). Their defining trait is that they can't speak Common; their voices are apparently "too high-pitched" for humans to make out, which is one of the stupidest racial quirks to come out of AD&D.

They are notable as one of the very few demihuman races, alongside the Lupin and Rakasta who could actually be Paladins in AD&D - in fact, one of the warrior kits in the Complete Book of Humanoids was the Saurial Paladin, to account for this. Of course, as with a lot of AD&D stuff, it was basically shoehorning the plot of the novels into game-crunch; intended to make the character "Dragonbait/Finder" game-viable, it was restricted to the Finheads alone.
