They said "the epithet carboniferous is of obvious application to this series".

Henry Shaler Williams (1891) proposed Pennine System as the name for the Carboniferous.

The amoeba has no hard part, but some single cell organisms produce microscopic skeletons or shells. Fossil evidence is consistent with these gene-based estimates. which, from a supposed resemblance.the blossom of a liliaceous plant have been denominated Encrinites". But things changed in the : There were no land animals and extinctions were confined to water life.

It mentions the following periods to indicate how long ago coal was formed: Carboniferous followed by 359,200,000 - 326,400,000 years ago Dinantian series or epoch from the Lower Carboniferous system in Europe 326,400,000 to 313,400,000 years ago Namurian stage in the regional stratigraphy of northwest Europe are found - Silicious Grit, providing stone for building and millstones - Shale - then lime-stone and toadstone alternately.

The veins of metallic ores appeared in the limestone.

The end-Frasnian extinction was most pronounced in tropical environments, particularly in the reefs of the shallow seas.

Reef building sponges called stromatoporoids and corals suffered losses and stromatoporoids finally disappeared in the third extinction near the end of the Devonian.

372,200,000 to 358,900 years ago Famennian age of the separated by about 10 million years.

About 375 million years ago, towards the end of a time interval called the Givetian.

It is suggested that analysis of sedimentary pyrite from the Belingwe sedimentary basin in Zimbabwe may provide evidence for bacterial reduction at this date.

2,500,000,000 to 542,000,000 years ago The Proterozoic Eon: the most recent part of the Precambrian Supereon.

The end-Frasnian extinction (the largest) about 375 million years ago.

The about 365 million years ago during the Famennian.

By carboniferous [carbon bearing] soils, Richard Kirwan in 1799 meant the "various sorts of earth or stone among or under which coal is usually found".
