In geology, petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Many animals regularly visit mineral licks to consume clay, supplementing their diet with nutrients and minerals. In tropical bats, lick visitation is associated with a diet based on wild figs (), which have very low levels of sodium, [3] [4] and licks are mostly used by females that are pregnant or lactating.
Animals are thought to better absorb, digest, and use mineral chelates than inorganic minerals or simple salts. [1] In theory lower concentrations of these minerals can be used in animal feeds.
