I read page 88 of 6th ed. rulebook, I think I can actually select to fight with the spear or the sword for the whole unit once per fight.
I vaguely remember people switching back and forth between spears and hand weapon and shield, but I don't know if that was an official rule or a common house rule.
Fun fact, Saurus used to have two attacks and it was only fairly recent, either 7th or 8th edition that supportng ranks only got one attacks. So if you had a two attack profile and spears, will for a period of time, all competitive players chose spears over hand weapons for Sauri.
Anyway there were lots of variations of special rules that nerfed this. At one point, I remember a Saurus specific rule that their supporting attacks didn't get the full attack profile. At another point Saurus had A1 but they had a special power that gave them a bonus bite attack so whatever their weapon was, their extra attacks were at base Strength and Weapon skill with no add-ons (which made Temple Guard sort of annoying as you got a halberd attack plus a weaker follow up attack, kind of like horses attacking after the knights attack.
After several evolution of Saurus Warrior bonus attacks, in 8th edition we got Predatory Fighter.

I'm pretty sure spears could only generate 1 supporting attack in 8th Edition.
Yes, but there was a period in 6th edition where we had an intermediate list from a White Dwarf magazine where Saurus infantry with spears got two attacks from the supporting ranks, and I remember the Temple Pyramid Vault gradually developing a consensus that spears were far superior to handweapons.
