In fact, no spider that large has ever been found; but, at the time the series began production, the sea scorpion Megarachne had been mistakenly interpreted as a spider. The correct classification was not made until Walking With Monsters was well into production, and the giant spider was left in and called "Mesothelae" instead of Megarachne. Megarachne servinei had up until this time been considered the largest known spider.
Well, this is both saddening & disappointing - I feel like I've been lied to now.

Especially as finding evidence from the carboniferous period is extremely hard at best, not to mention we're talking about a species of animal that rarely if ever leave behind fossils that survive a million years let alone 300 million +.

I'll just have to suffice with these instead.
