Kansajsuchus Extensus
''Kansajsuchus'' is an extinct genus of paralligatorid mesoeucrocodylian. It is holotype, based on Paleontological Institute of Russian Academy of Sciences, PIN 2399/301, a right premaxilla, one of the bones of the tip of the snout. This specimen was found in rocks of the lower Santonian-age Upper Cretaceous Yalovach Svita of Konsoy, Kansai, in the Fergana Valley, Fergana Basin of Tajikistan. Additional fossils including vertebrae and osteoderm, bony armor have been assigned to this genus. It would have been a large animal, estimated at between long. ''Kansajsuchus'' was described in 1975 by Mikhail Efimov. The type species is ''Kansajsuchus extensus''. Classification Halliday ''et al.'' (2013) confirmed the validity of the species ''K. extensus'', and its phylogenetic position among other basal (phylogenetics), basal goniopholidids from Asia. ''Sunosuchus shartegensis, "Sunosuchus" shartegensis'' was found to represent its sister taxon, and both species were placed in a ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...
