Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, "zone fossil", is used when the fossil has all the characters stated above except wide geographical distribution; thus, they correlate the surrounding rock to a biozone rather than a specific time period.
Since 2012, a Global Ambassador Team from Japan has been invited to attend the national tournament as part of a partnership between Science Olympiad, MEXT and JST.Each year, the Grand Prize for winning the Japan High School Science Championships (JHSSC), a competition styled after the U.S.-based Science Olympiad is a trip to the U.S. to participate in the Science Olympiad National Tournament.

Well-preserved basal arthropod Opabinia from Burgess Shale Lagerstätte (Middle Cambrian) . A Fossil-Lagerstätte (German: [ˈlaːɡɐˌʃtɛtə], from Lager 'storage, lair' Stätte 'place'; plural Lagerstätten) is a sedimentary deposit that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues.
Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. [57] Fossilisation is a rare event, and most fossils are destroyed by erosion or metamorphism before they can be observed. Hence the fossil record is very incomplete, increasingly so further back in time.
The National Science Bowl (NSB) is a high school and middle school science knowledge competition, using a quiz bowl format, held in the United States. A buzzer system similar to those seen on popular television game shows is used to signal an answer.
