Following burial, the minute shells may recrystallize or dissolve unless they are secured by mud that blocks the circulation of water, and those that survive as fossils are extremely beneficial to paleontologists thanks to their unaltered biominerals.

[fifty one] Because of the specialized and unusual situation expected for just a Organic composition to fossilize, only a little share of lifetime-varieties might be envisioned being represented in discoveries, and every discovery represents only a snapshot of the process of evolution. The changeover alone can only be illustrated and corroborated by transitional fossils, which will never show an exact half-way point.[fifty two]
