Gideon Mantell recognized dinosaurs as evidence for reptilian dominance over the land in addition to the dominion over the sea held by ichthyosaurs and plesiosaurs. He therefore declared the Mesozoic era to be the "Age of Reptiles". Distinguishing the Mesozoic "Age of Reptiles" from the Cenozoic "Age of Mammals" highlighted the differences ...
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of gymnosperms such as cycads, ginkgoaceae and araucarian conifers; a hot greenhouse climate; and the tectonic break-up of Pangaea.
During the Lower Paleozoic Era, Proto-Europe acquired a large piece of crust, known as East Avalonia, that would eventually become northwestern Scotland. [1] Avalonia itself would eventually separate into the eastern coastal region of North America, divided by the Atlantic Ocean, from southern Ireland, England, Wales, Belgium, and the Netherlands.
The mountains of northwest Ireland were formed during the collision, as was the granite that is found in locations in Donegal and Wicklow. The Irish landmass was now above sea level and lying near the equator, and fossil traces of land-based life forms survive from this period.
A European school led by Gabriel de Mortillet asserted that there was a gap between the earlier and later. Edouard Piette claimed to have filled the gap with his naming of the Azilian Culture. Knut Stjerna offered an alternative in the "Epipaleolithic", suggesting a final phase of the Paleolithic rather than an intermediate age in its own right ...
Alternatively, many hold the view that this happened with the bearers of the Bell Beaker culture, probably Indo-European speaking, reaching Ireland during the earlier stage of the Bronze Age. [56] The Celtic languages of Britain and Ireland, also known as Insular Celtic, can be divided into two groups, Goidelic and Brittonic.
Reconstruction of a hunter-gatherer hut and canoe – Irish National Heritage Park. Evidence of human activity during the Mesolithic period in Irish history has been found in excavations at the Mount Sandel Mesolithic site in the north of the island, cremations on the banks of the River Shannon in the west, campsites at Lough Boora in the midlands, and middens and other sites elsewhere in the ...
The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. Both the start and end of the period are marked by major extinction events . [ 10 ] The Triassic Period is subdivided into three epochs: Early Triassic , Middle Triassic and Late Triassic .
