- Dimetrodon (/daɪˈmiːtrəˌdɒn/ or /daɪˈmɛtrəˌdɒn/; lit. ’two measures of teeth’) is an extinct genus of non-mammalian synapsid belonging to the family Sphenacodontidae that lived during the Cisuralian age of the Early [Permian](Permian period, around 295–272 million years ago. With most species measuring 1.7–4.6 m (5.6–15.1 ft) long and weighing 28–250 kg (62–551 lb), the most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It was an obligate quadruped (it could only walk on four legs) and had a tall, curved skull with large teeth of different sizes set along the jaws.

Chanbara (チャンバラ), also commonly spelled “chambara”, meaning “sword fighting” films, denotes the Japanese film genre called samurai cinema in English and is roughly equivalent to Western and swashbuckler films. Chanbara is a sub-category of jidaigeki, which equates to period drama. Jidaigeki may refer to a story set in a historical period, though not necessarily dealing with a samurai character or depicting swordplay.
