11. Another interpretation of these structures is fossilization . 12. Depictions are necessarily conjectural, because petrification and other fossilization mechanisms do not preserve colors. 13. The fossilization began when the water receded. 14. Sometimes, though, fossilization can begin fast enough to prevent the eggs from being cracked. 15. The spores showed considerable damage from both the fossilization process and the subsequent weathering and specimen collection. 16. Since phosphate is mobile only in organic form this suggests the eggs were already decaying before fossilization . 17. Deprived of oxygen the wood undergoes the process of fossilization and a long process of morta formation. 18. Still, when it comes to modern fossilization , the conditions don't get much better than this. 19. Despite this effort, there still is a good deal of distortion from the fossilization processes that took place. 20. As soft parts are not prone to fossilization , little can be surmised as to their soft part anatomy.
