first geological surface map of England. In addition, based on rock specimens in his possession, he also
drew underground geological maps for some regions, which made a major contribution to the
advancement of modern geology and to determining the Earth's geological time frame. Thanks to the
information contained in his maps, the nature and contents (iron seams, coal, etc.) of the strata

immediately beneath the surface could be known, even if the rocks themselves were covered in
vegetation.
Fossils played a vital role in the acquisition of all his information. The geological time frame from the
Precambrian Period to the Quaternary period was drawn up using the data indicated by fossil beds, and

is still in use today. Thanks to investigations of rock structures, the stages undergone by the Earth at
different periods were identified, and the fossils inside rocks provided information about the organisms
that had existed during different periods. Combining these two together produced a chronology,
according to which the history of the Earth is separated into two eons, with those eons being subdivided

into eras and eras into periods.

In order to make natural history more
comprehensible, geologists and
paleontologists divided the history of
the Earth into geological periods.
While determining these periods, the
formation of rocks, their ages and the
fossils they contain play an important
role.
