Galagadon (/ ɡ æ l ʌ ɡ ə d ɒ n /) is an extinct genus of small carpet shark that lived during the Late Cretaceous period. It contains one species, G. nordquistae. It was named after the video game Galaga due to a resemblance between its teeth and the spaceships in the game, [1] and Field Museum volunteer Karen Nordquist.
Location of Hawaii in the Pacific Ocean. The O‘ahu ‘ō‘ō ( Moho apicalis ) is among dozens of bird species that became extinct after the human settlement of Hawaii. This is a list of Hawaiian animal species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before ...
This list of the Cenozoic life of Hawaii contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Hawaii and are between 66 million and 10,000 years of age.
The monstrous predator — which measured as long as a great white shark — belongs to a brand new species, according to a Dec. 12 University of Cincinnati news release.

The oldest of the Hawaiian islands is Kauai, of the archipelago's northwest.Kauai preserves lava flows that formed slightly more than five million years ago. [2] No non-avian dinosaur fossils have ever been found in Hawaii because the volcanic activity responsible for their creation did not begin until after their extinction. [3]
Megalodon sharks were “the size and weight of a railroad car” and reigned over the world’s oceans “roughly 23 to 3.6 million years ago,” according to the National Museum of Natural History.
The otodontid sharks have been considered to have been ectotherms, so on that basis megalodon would have been ectothermic. However, the largest contemporary ectothermic sharks, such as the whale shark, are filter feeders, while lamnids are regional endotherms, implying some metabolic correlations with a predatory lifestyle.
