I’m afraid these geoglyphs are not like the Nazca lines.....and I think we are straining a bit to see these patterns, we could do the same with clouds if we could hold them still......The geoglyphs in Nazca were for people in flying aircraft......and that is still a mystery
You seem to have nailed it.
Figure 6: This artificial landform could represent a hedgehog.
Coordinates of hedgehog are -15.65154,-70.1334 (upside-down).
HEDGEHOG!?! How old are these geoglyphs geophantasamicons* supposed to be?
There are 17 species of hedgehog in five genera, found through parts of Europe, Asia, Africa, and New Zealand. There are no hedgehogs native to Australia, and no living species native to North America; those in New Zealand are introduced.

I have wasted hours of my life looking at 'pictures' and 'figures' in clouds, linoleum, plywood paneling, "picture" sandstone, toast, burnt bottoms of frying pans, and abstract "art"...but all that was really there were natural, random, abstract patterns that the brain could arrange into familiar seeming figures.
*geophantasamicons: imagined pictures seen in land forms. (Akin to linoleophantasmaicons, the imagined figures seen in abstract linoleum patterns) i,e. SEEING 'CLOUD PICTURES' IN LAND FORMS!
