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...
The taphonomic conditions within these ‘Arctic’ paleo- polar sites were strongly influenced by long periods of pre-depositional transport.Similar content being viewed by others New Cockroaches (Dictyoptera: Blattodea) from French Guiana and a Revised Checklist for the Region Article 19 March 2019 ...
The cold climate of the second order of magnitude began with the last phase of the Jurassic period. High latitude snow increases, while the tropics are more humid than the Triassic and Jurassic periods. But glaciers are only found in high latitudes, while seasonal snow is still visible at low...
enhanced organic carbon burial and caused widespread ocean deoxygenation on a scale sufficient to drive recurrent anoxia. This model complements volcanic outgassing-centred hypotheses for triggering these events by demonstrating well-quantified basaltic sources of phosphorus release during periods of intense we...
The Age of Dinosaurs is the Mesozoic Era, which is divided into three periods: the Triassic (245-208 million years ago), Jurassic (208-145 million years ago), and Cretaceous (145-66 million years ago). The earliest dinosaur fossils, recently discovered i

(c) Mesophytes are plants that have some ability to resist periods of drought or to regulate their water metabolism in moist areas such as dry meadows or pine forests. (d) Xerophytes are plants that can resist long periods of drought and are living in stony steppes and dry rock outcrops...
Differences in the magma source area during different periods. Overall, a similarity on magma origin and a consistency of magma evolution have been observed according to geochemical characteristics of REE, trace element and isotope of volcanic rocks, sub-volcanic rocks and intrusive rocks in the ML...
New field investigations in the western part of the Greater Caucasus have allowed for the documentation of geological objects, the palaeogeographical interpretation of which indicates the existence of island mass in three time slices representing all periods of the Mesozoic, namely, the Induan (...
