Phosphatic Fossilization - How IT Happens

How It Happens

Plenty of phosphate is required, either from seawater or from the tissues of the decaying organism. In some cases microbes control the phosphatization, and the remains of the microbes that were "feeding" on the preserved tissue form the fossil. In other, the tissue itself is the source of phosphate and its phosphatized remains form the fossil. In the intermediate case the phosphatized tissue retains the impressions of the phosphatizing microbes.

Famous quotes containing the words how and/or happens:

    Funny ain’t it. Here I am worrying about a woman. Men don’t worry much about women when they’re around. But when it gets way off from home like we are now, and where he knows he’s going a lot further away ... I mean that’s when a woman gets workin’ in your mind. You reckon you’re a fool for not noticin’ before how, how big a part of things they be. There ain’t nothin’ like seein’ a woman’s face.
    Dudley Nichols (1895–1960)

    Oh, I love Proust. We all learned from him how to go back in time. The difference is that Proust stayed in his room, and he observed himself. He was Proust lying in his bed looking at Proust at the window who was looking at Proust in bed. In our generation’s case, we are always in the middle. We are never on the outside. Whatever happens, happens to us.
    Elie Wiesel (b. 1928)
