Input (English): This period saw the once dominant armored placoderm replaced with a wide diversity of sharks. During this period, Gondwana collided with Laurussia while southern Gondwanaland was glaciated, although that glaciation may have been a holdover from an earlier time. It saw the development of the amnoite egg, which allowed for extended dominance over land by some tetrapods. Trilobites were rare during this period but crinoids and gastropods were numerous and there were also many species of Eurypterids flourishing. It saw the appearance of bark-bearing trees and an overabundance of plants made the oxygen levels significantly higher allowing the evolution of giant-sized insects. Divided into the Pennsylvanian and Mississippian, FTP identify this last period of the Paleozoic Era, which started about 359.2 million years ago and which was named for the large amount of coals beds dating to that period.
