作者: RC Fox 摘要: The term Mammals, MesozoicMesozoic Mammals is purely informal and convenient, used to refer to mammals that lived during the Triassic, Jurassic, and Cretaceous periods, that is, during the first two-t DOI: 10.1007/3-540-31078-9_79 被引量: 14 年份: 1979 收藏...
The Mesozoic era brought substantial changes in global ocean chemistry, including several carbon isotope excursions (Fig.2c–f). These changes do not provide an unambiguous record of the relative magnitude of weathering inputs as geochemical proxies record contributions from multiple, simultaneous geolog...
If so, and if one considers differences of cycles of the same order between the periods of this era, it is difficult to apply "standard" hierarchical classifications to the documented cycles. The hypothetical uncertainty of the hierarchy of the Mesozoic long-term eustatic cycles is an important...

Mesozoic era is also called the age of reptiles. Reptiles dominated most of the Mesozoic era. The dinosaurs dominated the Jurassic period, while birds, flying reptiles, tiny mammals, tortoises and lizards lived in the Mesozoic era. What animals and plants lived during the Jurassic period? Cycads...
The era is subdivided into three major periods: the Triassic, Jurassic, and Cretaceous, which are further subdivided into a number of epochs and stages. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth’s history, and ...
Mesozoic Era is divided into three major geologic periods, which may be more familiar to us: the Triassic, the Jurassic, and the Cretaceous. The era is bounded by two mass extinctions at the end of the Paleozoic Era and the beginning of the Cenozoic Era, and is known as the Age of ...
The Mesozoic and Upper Palaeozoic have good hydrocarbon source rocks in Subei basin.However,suffered from the limitation of the seismic data and the reconstruction of multi-period tectonic movements,distribution and preservation of the Mesozoic and Upper Palaeozoic are controversial for years.In order to...
But this finding does not mean that they cooccurred in a stable fashion. We cannot rule out the possibility that ephippia were introduced from the surrounding (permanent or temporary) lentic water bodies during some high water periods, or by some lotic waters. Most commonly, the contents of ...
Finally, 474 of them can be linked to their closest parent plants and Eco-Plant model at family or order level. Based on the demands of the parent plants to different humidity conditions, the Eco-Plant model separates between hydrophytes, hygrophytes, mesophytes, xerophytes, and euryphytes....
