Archimedes (bryozoan) distanced rimmed pores. Inside the branches, neighbouring individuals were in contact through small canals. Bryozoans are stationary epifaunal suspension feeders. The majority of fossils of this genus are distributed throughout Europe and North America, but they have also been found in sediments of Afghanistan, Canada, Russia, and Australia. Archimedes (bryozoan) Archimedes is a genus of bryozoans belonging to the family Fenestellidae. The first use of the term "Archimedes" in relation to this genus was in 1838. This genus of bryozoans is named "Archimedes" because of its corkscrew shape, in analogy to the Archimedes' screw, a type of water pump which
SS Archimedes the Archimedes' screw, named after Archimedes of Syracuse who lived in the 3rd Century BC. It was not until the 18th century however, and the invention of the steam engine, that a practical means of delivering effective power to a marine screw propulsion system became available, but initial attempts to build such a vessel met with failure. In 1807, the world's first commercially successful steam-powered vessel, Robert Fulton's "North River Steamboat", made its debut. As this vessel was powered by paddlewheels rather than a propeller, the paddlewheel thereby became the "de facto" early standard for steamship propulsion. Experimentation with screw
