The early Cretaceous is marked by a major diversification of small theropods and ornithischians migrating to the riparian belt of central Kiravia. The paleobotany of the region appears to have changed in the period towards more leafy materials more easily digestible by small unspecialized browsers. This migration and change in vegetation is thought to be the main cause for the extinction of several lineages of [[Thagomizeroid|thagomizeroid]] species during the early Cretaceous, having been outcompeted by the more rapidly breeding and growing ornithischians. Paleontological evidence suggests however that the north of Kiravia did not change much during the early Cretaceous and that it continued to be inhabited by sauropods, large ornithischians like [[Thagomizeroid|thagomizeroids]] (notably ''[[Thagomizersaurus]]'') and the theropods that preyed on them.<ref>Lyukquar, Ansar: ''Kiravia and the Mesozoic'', pg. 81-88. 2015.</ref> | The early Cretaceous is marked by a major diversification of small theropods and ornithischians migrating to the riparian belt of central Kiravia.

During the late Cretaceous, the continent of Great Kiravia collided with the North Pole forming [[Kiroborea]]. This increased volcanic activity in the region, causing a number of minor local extinctions as evidenced by the layers of basalt and obsidian in the region.

This increased volcanic activity in the region, causing a number of minor local extinctions as evidenced by the layers of basalt and obsidian in the region. Towards the very late Cretaceous ({{circa}} 70-66 million years ago), the large [[Thagomizeroid|thagomizeroid]] dinosaur ''[[Ĥosaurus|Ĥosaurus rexkiraviensis]]'' was abundant in both the northern and riparian central regions of Great Kiravia, living alongside a wide variety of ornithischian and smaller theropod dinosaurs.<ref>Lyukquar, Ansar: ''Kiravia and the Mesozoic'', pg. 102-107. 2015.</ref> There is good evidence to support another major eruption of the supervulcano [[Gimænbayer]] around 66 million years ago, not unlike the [[Triassic–Jurassic extinction event]], which would have undoubtedly caused major waves of extinction within the Great Kiravian paleoecologic system. It is ultimately considered a contributing factor to the ultimate {{wp|Cretaceous–Paleogene extinction event}} which occured when a major meteor struck central [[Daxia]], causing the mass extinction of something resembling 75% of all life on Earth.<ref>Konsaháken, Vurdhan: ''Paleogeology of Great Kiravia'', [[University of Belarus]], pg. 4-5 + 49-53. 2012.</ref><ref>Balboa, Maximus: ''A comprehensive history of paleontology'', pg. 204-206. 2004.</ref> | ||
