I really don’t think so. I don’t know if the link showed the very sculpted rocks. Rectangular blocks. Did you already go to Chichen Itza? When I went I saw very rectangular stones with a tree growing like in the middle of the structure. That was a little pyramid before but with the tree right in the middle destroying the structure you could think that that was geological because it was so destroyed, but perfectly rectangular rocks are not a normal thing in the geological system.
Nature grow above and inside the pyramid of the Serra do Mar and destroyed the structure but I think this case is similar to what I observe in Chichen Itza.
In the medle of the Brazilian Amazon we have a Stonehenge:

Brazil it is not such a terrible Third world country. The corruption of the politics take money away from things like studying a lot of ancient structures we have here. There are some universities trying to do their work studying and saving this structures but if the government helped we would discover so many great things to rewrite the history of humanity. I talked about the corruption but don’t get me wrong, I love to live in Brazil. The people here are very happy and very kind. I love my people. What I don’t like it is that the government doesn’t care about the great things we have here.
What makes things more difficult is that on Amazon we have a lot of indigenous tribes that never ever contacted civilization and they are protected by FUNAI. I agree with this protection but I wonder what is hide on Amazon that we are never know?
