These gaps are represented by the periods from where there are no relevant fossils records.
Romer's gap is given by the paleontologist i.e Alfred Romer, who was the first to coin it. Romer's gap spanned from about 360 to 345 million years ago, with the corresponding gap to first occur over the period of 15 million years of the Carboniferous Period.
Du to the distinctions found in the geochemistry of the rocks that did not favor the development of the fossils may be due to the evolution of history or the occurrence of a natural disastrous event.
