Actually spiders never really got that big, as far as we are aware.

Interesting. We know for sure that scorpions, dragonflies, and certain worm types were hundreds of times larger than today's species.

Well, that was maybe 250 mln years ago, and mammals only appeared maybe 80-100 mil years ago, when insects were already closer to today in size

Weren't they micro fauna initially? Like prey to pretty much anything?

Afaik, the first proto-mammals were therapsids, which were not that small. However, most mammals (or all?) I can't remember - came from rodent-like creatures after the cretaceous extinction event 65 mil ago. But that time insects were definitely even smaller...

Not really. Back then mammals were much smaller so our records aren't to scale
