What is Lignite? (with picture)
Some geologists estimate that it formed roughly 251 million years ago, during the Mesozoic and Cenozoic eras. In general, the fuel is thought to have been formed from peat at shallow depths and at temperatures less than 212°F (about 100°C).

Coal
The younger era of coal formation began about 145 million years ago, during the Cretaceous Period, and reached its peak approximately 66 million to 2.6 million years ago, during the Paleogene and Neogene periods of the Cenozoic Era. Most of the coals that formed during this later era are lignites and subbituminous (brown) coals.
