Mesozoic

related rocks slightly changed from their Mississippian positions compare to the subjacent Paleozoic shelf rocks. (2) The eastern limit of the lower Paleozoic oceanic rocks is the approximate trace of the Roberts mountains thrust, and (3) if a regional Mesozoic decollement extends from eastern to western Nevada, it lies deeply within or below the Paleozoic shelf succession. In addition, the position and extent of the Antler orogeny is uncertain outside the central…

turbinates in dinosaurs indicates that they were likely to have maintained reptile-like metabolic rates during periods of rest or routine activity. But there are also several logics which indicate these hypotheses may be false. • The climate in the Mesozoic era was varied, and dinosaur fossils are found in some areas that were cooler and less mild then, including high altitude and polar regions. • Not all adult dinosaurs were large. The weight range was from about 5 kg to 80 or so tons. Even the…

George Gaylord Simpson (1902-1984), an American paleontologist who moved often from New York's American Museum of Natural History, where he was curator, to lecture halls and also to visit far away fossil fields that weren't open to the public. His total understanding and grasp of the fossil record allowed for significant advances in theoretical evolution and taxonomy. To further explain the previous paragraph the reader must understand a few terms. A curator is in charge of keeping up with…

TECTONIC HISTORY The Smackover Formation of Texas is located in the East Texas Basin, in North-East Texas, and is “one of three Mesozoic basins flanking the northern rim of the Gulf Coastal Plain” (Foote et al., 1988, p.3). “Subsidence from rifting and crustal attenuation in addition to subsequent sediment loading results in a maximum of 23,000 feet of subsidence in the center of the basin” ( an idea originally published in Seni and Jackson,1984, quoted from Foote et al., 1988, p.3). The area…

Whilst on holiday in São Paulo, Brazil, I noticed that the soil colour was completely different to the soil colour in the UK and in order to understand why, I visited the ‘Museu Catavento Cultural e Educacional’. I discovered that the soil has a high-iron content because it originates from what was possibly one of the largest volcanic spills in the Earth’s history and as the spill contained magnetite, the soil in southern Brazil is incredibly fertile where it’s called Terra Roxa. This type of…

could swear I saw the word vrmmorpg mixed in with the pile of sub-standard console games. I moved these “gems” aside until I found what I was looking for. It was indeed a vrmmorpg game. I’d never seen one in the bin-o-crap before. It was called Mesozoic wars. The cover showed an action shot of a caveman jumping towards a armor clad humanoid reptile while holding a big rock over his head. Surprisingly, I knew nothing about this one, which was rare as I keep myself well informed on everything…

the Jurassic Time Period and it will give information about that dinosaur as well. Vertebrates taking to the air like the pterosaurs and the first birds. This was the Jurassic Period, 199.6 to 145.5 million years ago, a 54-million-year chunk of the Mesozoic Era. Air, land, or sea, dinosaurs came in all shapes and sizes in many different places around the world. The first dinosaur that I will be telling you about is the Dilophosaurus, this carnivore walked on two legs and unlike the movie…

represented in the basement rocks or eastern Australia. The rocks make up one third of Australia’s landmass. The orogeny extends along the eastern seaboard from the Tasmania in the south to Queensland in the north. In the early Paleozoic to early Mesozoic Australia was located on the eastern side of the Gondwana super continent. It was situated above Antarctica to the northeast of India. The tectonic processes that increased in the size of the Australian continent to the size that it…

referred to as the Permian-Triassic extinction, in Earth’s history shifting Earth into a new era: The Mesozoic Era. Frequently mentioned to as “Age of Reptiles” due to the amount of reptiles that predominated the lands, however they were not alone; land-dwelling vertebrate animals and vast amount of plants, insects and fish also existed among them. By the time span of 180 million years the Mesozoic Era has been divided into three major divisions, from oldest to youngest, Triassic Period, the…

Developmental Stages This term is interesting to me for multiple reasons. I enjoy watching those around me grow and develop. I find fascinating how different people mature. How some pick up different ideas and things quicker than others. For example, watching one of my friends lose her mother last year has taught her to mature and try to become a mother figure herself for her younger siblings. I, on the other hand, have my mother, therefore, I do not have to be a mother figure to my sister.…
