From a quick search these spiders aren’t that big

25-28mm body length is quite a considerable size. I think a cousin of these is often dubbed the "UK's largest spider", even though it technically isn't. But they are up there. Yes, the US has tarantulas, giant house spiders and some larger wolf spiders, but Dolomedes is up there as well.

The sizes make sense - the turtle is on the smaller end and likely a juvenile, but both seem appropriately sized - the spiders can grow that big, especially if female.

I found this in a group for spider enthusiasts - these are the kinds of geeks that will look at a spider leg and get it down to class. AI is not good at generating invertebrate species specific traits yet. While this is pretty spectacular - not a daily event - these are both species that can be found in the same area, and these spiders will attack vertebrate pray.

"I wouldn't call it funny, per se, but I remember it..."

Yeah, many larger spider species will go after smaller vertebrates. Goliath bird eaters (South American) will go after snakes much larger than they are - despite the name, they aren’t inclined towards birds though.
