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.
As of 2020, estimated costs of production are $1–1.80/kg for grey hydrogen and blue hydrogen, [177] and $2.50–6.80 for green hydrogen. [177] 94 million tonnes of grey hydrogen are produced globally using fossil fuels as of 2022, primarily natural gas, and are therefore a significant source of greenhouse gas emissions.

Stromatolites are a major constituent of the fossil record of the first forms of life on Earth. [24] They peaked about 1.25 billion years ago (Ga) [ 22 ] and subsequently declined in abundance and diversity, [ 25 ] so that by the start of the Cambrian they had fallen to 20% of their peak.
Thomas is mounted in a "growth series" with the youngest-known Tyrannosaurus rex fossil, a two-year-old, 11-foot-long (3.4 m) specimen, and a 13-year-old, 20-foot-long (6.1 m) juvenile specimen. [99] This fossil is one of the geologically youngest T. rex specimens known, discovered very near the Cretaceous–Tertiary boundary. [100]
As of 2022, usage in products consumes around 1% of the CO 2 captured each year. [114] In the production of urea, an important agricultural fertilizer, CO 2 generated within an industrial process is often recycled and reused. However, by convention, this type of internal recycling is not included in figures on carbon capture. [115]
