It's a prehistoric fossil, I need to know how big (or small) this was. Since it's so old my mind is just like, yahhh go ahead and assume its like 2 feet long, but its probably only an inch or two at max.
Kids, always include a scale with your models.
If Wikipedia is correct, this order has an upper limit of 5cm. So big, but not a spot on the largest extant spiders.
