  2. Vero man - Wikipedia

    The human bones excavated by Sellards were passed around various institutions for study. By the time carbon-14 dating of fossils became possible, about 35 years after the discovery of Vero Man, some of the bones had been lost, and others had been rendered unusable for such testing due to the way they had been preserved with chemicals.

  3. Carbonaceous film (paleontology) - Wikipedia

    en.wikipedia.org/wiki/Carbonaceous_film...

    Sometimes, fossils contain only carbon. Fossils usually form when sediment buries a dead organism. As sediment piles up, the organism's remains are subjected to pressure and heat. These conditions force gases and liquids from the body. A thin film of carbon residue is left, forming a silhouette of the original organism called a carbon film. [1]

    Mineralization occurs when dissolved minerals replace the cellular structure of the ecofact or encase the ecofact in places such as caves, rock shelters or cesspits. The Roman latrines found at Sagalassos in Turkey are an example of mineralized ecofacts that have occurred due to the plant remains absorbing minerals that were present in the ...

    Small shelly fossils are composed of a variety of minerals, the most important being silica, calcium phosphate and calcium carbonate. [3] The minerals used by each organism are influenced by the chemistry of the oceans the organism first evolved in, but then continue to be used even if the ocean chemistry changes.

    The fossils include what may be metazoan blastulas, possibly animal embryos at an early stage in cell division. The Doushantuo Formation presents a classic example of phosphatic fossilization: [excessive quote] 'This high-resolution fossil bed is about 30% phosphate, present as the mineral fluorapatite [Ca 5 (PO 4) 3 F].
