The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself.

Eve's footprint is the popular name for a set of fossilised footprints discovered on the shore of Langebaan Lagoon, South Africa in 1995. They are thought to be those of a female human and have been dated to approximately 117,000 years ago.
A derived, reworked or remanié fossil is a fossil found in rock that accumulated significantly later than when the fossilized animal or plant died. [100] Reworked fossils are created by erosion exhuming (freeing) fossils from the rock formation in which they were originally deposited and their redeposition in a younger sedimentary deposit.
Bison antiquus is known from fossils found across North America south of the Laurentide Ice Sheet (whose southernmost extent is around the modern United States-Canada border), ranging from southern Canada (southern Alberta [8] and Ontario [10]) in the north, and Washingon State [11] and California [12] in the west, southwards to Southern Mexico [9] and eastwards to South Carolina and Florida.
Prehistoric Trackways National Monument is a national monument in the Robledo Mountains of Doña Ana County, New Mexico, United States, near the city of Las Cruces.The monument's Paleozoic Era fossils are on 5,255 acres (2,127 ha) [1] of land administered by the Bureau of Land Management. [2]
State fossils are distinct from other state emblems like state dinosaurs, state stones, state minerals, state gemstones or state rocks and a state may designate one, a few, or all of those. For example, in Arizona , the state stone is turquoise and the state dinosaur is Sonorasaurus thompsoni yet the state fossil is petrified wood .
The fossils were first uncovered during the school’s modernization project, which began in 2022. The first find was unearthed in June 2022 beneath the school’s main courtyard, ...
The evidence of fossil flora and fauna using indicators such as the fossilized teeth of voles, which provide very accurate dating evidence, pushes the lower limit back to at least 840,000 years ago. On this basis, the range of possible dates for the deposition of the sediments that the footprints were found in stretches from 850,000 to 950,000 ...
