One remarkable drawing, a Nazcan spider, measures some 150 feet in length formed by one continuous line. What is remarkable about this drawing is that it depicts a unique spider -- a member of a spider genus known as Ricinulei which is of such rarity measuring less than an eighth inch in size and is found only living beyond the reach of sunlight in the Amazon rainforest nearly 1,000 miles from these Nazcan drawings.
In other words, the drawing is Nazcan; the spider isn't!

A usually overlooked fact about these drawings has to do with their location.
All these drawings are extant today because they were constructed in a region
of limited rainfall on soil that hardly erodes and becomes muddy. Those ancients think of everything, don't they?
