Where can I find official lore information on Saurials?

In D&D 5e, Tomb of Annihilation includes Dragonbait, a saurial. This is a race that I have gathered in my online research existed in previous editions of D&D, but besides the slivers of information included on Dragonbait, to the best of my knowledge 5e does not have much to say about them.

I’m interested in learning more about this race from previous editions. What source books (or magazines of whatever) from previous editions would I best look into in order to do that? I believe it’s likely to be 2e or 3.Xe material, but I still don’t know the names of the books/magazines to look into.

Note that I’m only interested in lore, not information on mechanics, stats, gameplay, etc. I’m not interested in books that only describe gameplay information.

In this case, lore includes things like lifespan, behaviour, habitat, religion, etc (some of this I’ve found on the Forgotten Realms wiki, but it doesn’t go into much detail, for example it doesn’t mention their lifespan).
