All of the changes that occur to a fossil (or more generally any sediment) after initial burial; includes changes that result from chemical, physical as well as biological processes. The study of diagenesis is part of taphonomy.

In geology and oceanography, diagenesis is any chemical, physical, or biological change undergone by a sediment after its initial deposition and during and after its lithification, exclusive of surface alteration (weathering) and metamorphism. These changes happen at relatively low temperatures and...

All chemical, physical, and biological modifications undergone by a sediment after its initial deposition.

In geology, the physical, chemical, and biological processes by which a sediment becomes a sedimentary rock. The main processes involved include compaction of the grains, and the cementing of the grains together by the growth of new minerals deposited by percolating groundwater. As a whole, diagenes...

The set of processes that cause physical and chemical changes in sediment after it has been deposited and buried under another layer of sediment. Diagenesis may culminate in lithification.

All the physical, chemical, and biologic changes undergone by sediments from the time of their initial deposition, through their conversion to solid rock, and subsequently to the brink of metamorphism.

The physical and chemical changes undergone by a sediment during lithification and compaction, excluding erosion and metamorphism.

The process that changes sediment into rock. This happens by the water being squeezed out, mineral grains being organised or chemically changed and the whole being cemented by minerals precipitated from peculating mineralised water.
