3.7" Prehistoric Coprolite Fossil Specimen Poop Dung Miocene Age Madagascar COA Mako these chemical reactions cause malachite

these chemical reactions cause malachite to crystallise slowly in successive layers

the continuous deposition of minerals leads to permineralization or petrification

is characteristic of fish that feed near the water’s surface

allowing it to catch and subdue large prey

which hunted them during these migrations
