In addition to the organic films, parts of many Burgess Shale creatures are preserved by phosphatisation.

Phosphatisation and the presence of other enzymes means that guts and mid-gut glands are often preserved.

However, phosphatisation was very rapid in the Doushantuo, so it's possible that faster preservation allowed embryos in different regimes to be preserved.

The preservational mode of the Doushantuo formation involves very early phosphatisation on a cellular level - with cells being replaced by phosphate before they degrade.

This cannot result from phosphatisation, which is usually responsible for 3-D gut preservation, for the phosphate content of the guts is under 1%; the contents comprise quartz and muscovite.

In some cases microbes control the phosphatization, and the remains of the microbes that were "feeding" on the preserved tissue form the fossil.

No guano deposits are present in the caves; phosphatization is believed to occur from river water containing organic matter penetrating the cave.

(3) Phosphatization: Phosphatization is a type of rare diagenetic processes.

The preserved embryos from China and Siberia underwent rapid diagenetic phosphatization resulting in exquisite preservation, including cell structures.

(1985) showed more active leaching and mineralization, notably phosphatization, of the underlying soil, with rapid run-off of soluble nutrients to the sea.

Phosphatization can be microbially mediated, especially in decay-resistant groups such as arthropods; or substrate-dominated, where phosphate-rich tissue leads the mineralization process (as in fish).

Many fossils, such as the Cambrian Small Shelly Fauna (SSF), are preserved through secondary phosphatization.

Phosphatization can happen quickly: The chitinous structures that support bivalve gills can be replaced by calcium phosphate, with a little help from co-occurring bacteria, in just two to six days.

Since the Georgina assemblage includes larger fossils and most Early Cambrian halkieriids are preserved by the same method, phosphatization, it is unlikely that preservational bias has produced an unrepresentative sample.

Higher concentrations of phosphate in the sea water do not enhance phosphatization, as may seem natural; rather, it increases the rate at which the organism breaks up, perhaps because the mineral "fertilizes" the decay micro-organisms.
