Online exhibits: Geologic time scale: Mesozoic Era. The Triassic Period. In many ways, the Triassic, lasting from 251.0 mya to 199.6 mya,* was a time of transition. It was at this time that the world-continent of Pangea existed, altering global climate and ocean circulation. Geologic History. Today, Utah is a land of great geologic diversity and scenery. Many factors have determined the evolution the state has undergone through time. In a sense, it could be said that Utah has had many different faces. Through geologic time, what is now Utah has been covered by oceans and inland seas as well as completely dry land.Quaternary to Mesozoic. Figure D.13-1 shows the geologic time scale indicating the breakdown of geo-logic time units and corresponding ages.

The Mesozoic Era was the geological era in which dinosaurs lived, as well as the first mammals. It lasted about 186 million years, starting 252.2 mya (million years ago) with the P/Tr extinction and ending 65 mya with the K/T extinction (the one that killed all dinosaurs except birds). [1]

Reptile - Evolution, Paleontology, Adaptation: The first land vertebrates, the Tetrapoda, appeared near the middle of the Devonian Period. The earliest known reptiles, Hylonomus and Paleothyris, date from the Late Carboniferous. The Mesozoic Era is known as the “Age of Reptiles.” Today's reptiles represent only a fraction of the reptile groups and species that have lived.Mesozoic翻译：中生代的。了解更多。 Mesozoic igneous activity is largely responsible for this diversity of mineral deposits and the mineral concentrations have been variably enhanced by hydrothermal activity associated with faulting.Numerous plants and animals abruptly cease to appear in the fossil record when transitioning from rock strata marking the end of the Cretaceous to those denoting the start of the Cenozoic (the era succeeding the Mesozoic). Frequently, there is a slender layer of clay between the final layer of Cretaceous rock and the initial layer of Cenozoic rock.The onshore Canning Basin covers an area of about 530,000 km 2 in central-northern Western Australia, and extends offshore for a total basin area of more than 640,000 km 2, of which 110,000 km 2 is in State waters. The succession in the onshore basin ranges in age from Ordovician to Cretaceous, but is predominantly Paleozoic.Mesozoic (252-66 million years ago) means 'middle life' and this is the time of the dinosaurs.

During the Mesozoic era on the passive continental margin in the northern part of Bengal and Bangladesh, there was a 100-km-wide shelf that deepened eastwards into the ocean basin (Johnson and Alam 1991 ). It began to subside in the Lower Cretaceous (at 127 Ma) when the Indian plate drifted away from Antarctica.Mesozoic (Smithsonian Institution) The world during the Mesozoic Era was a place both foreign and yet familiar when compared to Earth today.
