Science Resurrects Prehistoric Spiders

That intentionally "whip you into a needless frenzy" headline is on purpose. Because in truth, the smart people who do things like this have only done so by way of 3D X-Ray technology. Which, looking at these evil looking monsters, is already crossing the line. These things are gone for a reason (and thank goodness too).
The article about these 8-legged nightmares doesn't say how big they got, but putting the words pre-historic and spider together conjures images I would much rather not think about. Fortunately, no one is trying to clone one of these. Yet.
