Cenezoic
The Cenozoic Era spans the interval from 66 million years ago to present. It is divided into the Paleogene Period (66–23 million years ago) and Neogene Period (23 million years ago to present).

Cenozoic ...The Cainozoic ( Cenozoic) is the current geological era. It began 66 million years ago and continues today. Before it was the Mesozoic . During the Cainozoic the continents moved into their present positions. The climate started warm, but cooling continued steadily. Finally ice ages occurred. The Western Ghats-Sri Lanka biodiversity hotspot is home to three endemic Lygosomine (Reptilia, Scincidae) skink genera—Kaestlea, Ristella and Lankascincus.Phylogenetic reconstructions in the past have suggested a sister relationship between the Western Ghats endemic Ristella and the Sri Lankan endemic Lankascincus, while the placement of Kaestlea has been uncertain.Sea level was higher during most of the Cretaceous than at any other time in Earth history, and it was a major factor influencing the paleogeography of the period. In general, world oceans were about 100 to 200 metres (330 to 660 feet) higher in the Early Cretaceous and roughly 200 to 250 metres (660 to 820 feet) higher in the Late Cretaceous than at present.It was also the time when the Earth’s flora and fauna evolved toward those of the present. The Cenozoic, from the Greek for “recent life,” began c. 65.5 million years ago and is divided into three periods: the Paleogene (65.5–23 million years ago), Neogene (23–2.6 million years ago) and Quaternary (2.6 million years ago to the present).

Feb 24, 2019 · The Tertiary Period (65 million years ago to 2.6 million years ago) The first period in the Cenozoic Era is called the Tertiary Period. It began directly after the K-T Mass Extinction (the “T” in “K-T” stands for “Tertiary”). At the very beginning of the time period, the climate was much hotter and more humid than our current climate. We propose that the Cenozoic ultrapotassic mafic rocks in the central Tibetan Plateau originated in the lithospheric mantle metasomatized by the subduction-related components, and are the magmatic response to the detachment of the subducted Tethyan slab. Post-collisional (ultra)potassic lamprophyre dykes are the key probes for understanding ...
Over the Late Cenozoic (from 30 Ma), we predict a long-term decrease in preserved continental sediment volume. Negative rates in Fig. 5A represent erosive periods (particularly along continental margins) that translate into stratigraphic hiatuses and explain the observed mismatch between estimated and simulated sediment accumulation rates ( …Figure 13. Evolving slab windows according to the reconstruction of Dickinson (1997). In this reconstruction, plate boundaries are plotted on an unrestored base map of southern California. For each time (23, 19.6, and 17.5 Ma), the corresponding slab window is delimited on its north and east by solid lines. The east-west line along the northern boundary of each window represents the Mendocino ...
