The '''Kubagne Archipelago''' is a paleogeographic region of central [[Kubagne]], [[Yonderre]]. Whilst currently deep within the modern nationstate [[Yonderre]], the region represented an archipelago within an inland sea of the supercontinent [[Sarpolevantia]] during the early [[Cretaceous]] period {{circa}} 130-120 million years ago. The Kubagne Archipelago was made significant through [[Paleontology in Yonderre|paleontological]] expeditions to the sites of the previous archipelago that have uncovered important discoveries from which paleontologists could extrapolate much not only about early Cretaceous paleobiology and paleoecology but which also confirmed established theories regarding {{wpl|Island syndrome|island syndrome}}, not least regarding {{wpl|Insular dwarfism|insular dwarfism}} and {{wpl|Island gigantism|island gigantism}} in the Cretaceous period. The Kubagne Archipelago is thus made significant beceause very few other definite islands and archipelagos are known from before the {{wpl|Cretaceous–Paleogene extinction event}} 65.5 million years ago, and none have been studied as thoroughly as the Kubagne isles. | The '''Kubagne Archipelago''' is a paleogeographic region of central [[Kubagne]], [[Yonderre]].

The Kubagne Archipelago was probably located at least 200 kilometres (120 mi) from the nearest land mass. The Kubagne Archipelago itself was surrounded primarily by a deep marine basin, unlike some of the surrounding islands and land masses which were surrounded by shallow seas that is thought to on occasion have frozen solid enough that it allowed migration between the islands. During the {{wpl|Barremian}}, the climate of the Kubagne Archipelago was subtropical, with an average temperature of 20–25 °C (68–77 °F). The island experience marked rainy and dry seasons, but despite this, the plant life on the island was mainly tropical in nature. Carbon isotopes indicate dry woodland conditions. This seeming contradiction between the seasonally dry climate and tropical plant species can be explained by the fact that tropical plants can thrive in a seasonally monsoonal environment today as long as they have access to sufficient amounts of water year-round, and the [[Kubagne]] environment seems to have been dominated by braided rivers and lakes. Early rock layers are dominated by volcanic deposits, but these are absent in higher layers, indicating that volcanic activity dropped off during this time. | The Kubagne Archipelago was probably located at least 200 kilometres (120 mi) from the nearest land mass.
