An index fossil is a rare object that is more common than it should be due to occurring from small objects surrounded by empty space.
Examples
- Lidka is a 29,055-generation methuselah. As of July 8, 2022, Catagolue's combined C1/G1 censuses would have 56,503 methuselahs lasting between 29,000 and 30,000 generations if the number of methuselahs in each grouping of 1,000 generations decayed exponentially. However, as of that day, it has 71,735 (×1.27), which is explained by an abundance of Lidka results. (http://catagolue.hatsya.com/census/b3s23/C1/methuselah)
- There is a 1,376-generation diehard in even fourfold rotational symmetry (C4_4) that consists of four H' (generation 22 of the Herschel without the glider) and four blocks. As of July 8, 2022, the number of diehards in the 1100-1199, 1200-1299, 1300-1399, 1400-1499, and 1500-1599 bins are 20227, 6435, 5593, 6041, and 651 respectively; the huge boost to the 1300-1399 and the 1400-1499 bins can be seen. The reason both bins get boosted is because it often takes time to get to the generation with the canonical H'. (http://catagolue.hatsya.com/census/b3s23/C4_4/messless)
- Omnibus is a 40-cell still life. Its initial configuration of a pi-heptomino and two blinkers can be see on its page; as it takes a lot of space to form, it requires empty space around it.
