The Ottoman Empire was an imperial state that was founded in 1299 after growing out of the breakdown of several Turkish tribes. The empire then grew to include many areas in what is now present-day Europe. It eventually became one of the largest, most powerful and longest-lasting empires in the history of the world.
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.
