Live Science describes the dead animals as having “chalky sodium carbonate deposits outlining their bodies. “A calcified flamingo, preserved by the highly basic waters of Tanzania’s Lake Natron and photographed by Nick Brandt,” reads National Geographic’s caption of one of the photos included in the Facebook post. The photographs included in the post were taken by photographer Nick Brandt in 2013, who collected the animal carcasses around the lake’s shoreline and posed them for the pictures, the outlet reported. The dead animals in the photos were not instantly turned to stone by the lake, but rather became calcified due to the characteristics of the lake, according to National Geographic. “Any animal which touches the lake turns into stone.” (RELATED: Does This Image Show A Heart-Shaped Pond In Zimbabwe?)

“Natron Lake in Tanzania is the most (sic) deadliest place for animals,” reads text included in the image.

The image shows what appears to be the petrified remains of two birds sitting on a body of water. An image shared on Facebook claims it turns any animal that touches it to stone. The unique biodiversity was named to the Ramsar List of Wetlands of International Importance by Tanzania, recognizing the fundamental ecological functions of the lake. The home, and breeding grounds it represents for flamingos, make it even more important to preserve it in all of its beauty. Lake Natron in Tanzania is a saltwater lake with a pH of 10.5 (nearly as high as that of ammonia) and temperatures up to 140 degrees Fahrenheit, according to Smithsonian Magazine. Lake Natron is a prime example of a natural wonder.
