Exutaspis megista is an extinct, "giant" buchanosteid arthrodire placoderm. Its fossils have been found in the Late Emsian-aged marine strata of the Jiucheng and Haikou Formations in Wuding, Yunnan.

It was originally described as a phlyctaeniid. Later, after comparison with the Chinese Buchanosteus guanxianesis, Exutaspis was reappraised as a buchanosteid. The holotype, a "head roof," is 21 cm (8.3 in) long.

The Bronze Age is a historical period lasting from approximately 3300 to 1200 BC. It is characterized by the use of bronze, the use of writing in some areas, and other features of early urban civilization. The Bronze Age is the middle principal period of the three-age system, between the Stone and Iron Ages. This system was proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition.

The Cretaceous is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin creta, "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation Kreide.

Toyotomi Hideyoshi, otherwise known as Kinoshita Tōkichirō and Hashiba Hideyoshi, was a Japanese samurai and daimyō of the late Sengoku and Azuchi-Momoyama periods and regarded as the second "Great Unifier" of Japan. Although he came from a peasant background, his immense power earned him the rank and title of Kampaku and Daijō-daijin, the highest official position and title in the nobility class. He was the first person in history to become a Kampaku who was not born a noble. He then passed the position and title of Kampaku to his nephew, Toyotomi Hidetsugu. He remained in power as Taikō (太閤), the title of retired Kampaku, until his death. It is believed, but not certain, that the reason he refused or could not obtain the title of shogun (征夷大将軍), the leader of the warrior class, was because he was of peasant origin.
