Lake Natron in Tanzania has high levels of sodium carbonate and pH that can petrify animals.
Infact verdict: True (91/100).
The claim that Lake Natron in Tanzania has high levels of sodium carbonate and pH that can petrify animals is supported by multiple high-quality sources. Live Science confirms that the lake's high alkalinity, due to sodium carbonate and other minerals, can preserve animals as calcified mummies. This process is not true petrification but rather a form of preservation due to the lake's caustic environment. The evidence supports the claim's factual basis, though it clarifies the nature of the preservation process.
