"Ibn Sina made the following observation on the theories held at the time on fossils and the petrifaction of plants and animals: ""If what is said concerning the petrifaction of animals and plants is true, the cause of this (phenomenon) is a powerful mineralizing and petrifying virtue which arises in certain stony spots, or emanates suddenly from the earth during earthquake and subsidences, and petrifies whatever comes into contact with it."
ಸಸ್ಯಗಳು ಮತ್ತು ಪ್ರಾಣಿಗಳ ಕಲ್ಲಾಗುವಿಕೆಯಿಂದ ಪಳೆಯುಳಿಕೆಗಳು ಹುಟ್ಟುವುದಕ್ಕೆ ಸಂಬಂಧಿಸಿದಂತೆ, ಇಬ್ನ್‌ ಸಿನಾ ಈ ಕೆಳಗಿನ ವಿವರಣೆಯನ್ನು ನೀಡಿದ: If what is said concerning the petrifaction of animals and plants is true, the cause of this (phenomenon) is a powerful mineralizing and petrifying virtue which arises in certain stony spots, or emanates suddenly from the earth during earthquake and subsidences, and petrifies whatever comes into contact with it.
