FIG. 1,'11111 ...The team found that in their Late Cretaceous ecosystem in Alberta, mean annual temperature was about 16–20 degrees C (61-68 degrees F), a bit cooler than modern-day Louisiana, but much warmer than Alberta today, reflecting the hotter greenhouse climate that existed globally about 76 million years ago. Characterizing how these ecosystems were ...

(Note that the Cretaceous System is only divided into an Upper Cretaceous and Lower Cretaceous System. Although some geologists refer to a "Middle Cretaceous", that is not a formally recognized unit. If you want to talk about the upper part of the Lower Cretaceous and the lower part of the Upper Cretaceous, it is best to refer to it just as the ...The Lower Cretaceous system includes the major sedimentary cap and the main oil-bearing series in the area (Wang et al., 2012). The potential source rocks are mainly distributed in the K 1 s, K 1 d, K 1 t, and K 1 a 2 Formations.Cretaceous Period - Dinosaurs, Plants, Marine Life: Although the fossil record is irregular in quality and quantity for the Early Cretaceous, it is obvious that dinosaurs continued their lengthy dominance of the land. The Late Cretaceous record is much more complete, particularly in the case of North America and Asia.

To understand the diversity of dinosaur clades prior to this event, as well as recovery by avian dinosaurs (birds), we need a better understanding of the global fossil record.Both surface and bottom waters were affected, although the cooling signal is more evident in the data for surface waters. This pattern of cooling ascribes the deterioration of the Late Cretaceous climate to decreased CO 2 in the atmosphere and changes in the oceanic circulation correlated with enhanced meridional circulation.
Geology Subdivisions The Cretaceous is divided into Early and Late Cretaceous epochs, or Lower and Upper Cretaceous series. In older literature, the Cretaceous is sometimes divided into three series: Neocomian (lower/early), Gallic (middle) and Senonian (upper/late).
