Thank you for your comment! You’re absolutely right, South America does indeed have fascinating tunnel networks, some of which were likely created by extinct megafauna like ground sloths and glyptodonts. These large creatures are believed to have dug these tunnels as they moved through the region. The claw marks on the tunnel walls provide compelling evidence of their activity. It’s amazing how these ancient animals left behind such enduring structures that we can study today 🌍🦕 Thanks for your contributions 🚀
