Excerpt: Enormous cat etched into a hillside in the desert in Peru. Home to the geoglyphs of a hummingbird, a monkey, a spider and a human, the newly revealed form of the feline is about 37-meter-long, and expected to be dating back more than 2,000 years.
Edit: Updated source with higher quality photo. OP picture replaced with this photo.
It’s a pampas cat, per PBS.
