  2. Permineralization - Wikipedia

    en.wikipedia.org/wiki/Permineralization

    These three-dimensional fossils create permanent molds of internal structures. The mineralization process helps prevent tissue compaction, distorting organs' actual size. A permineralized fossil will also reveal much about an organism's environment and the substances found in it since it preserves soft body parts.

  3. Endocast - Wikipedia

    en.wikipedia.org/wiki/Endocast

    Endocast fossils from animals with shells that easily disintegrate or dissolve can often be encountered free from their mold fossil, like the aragonite shells of certain molluscs and the tests of sea urchins. A frequently occurring form is the internal mold of brachiopods and bivalves.

  4. Skhul and Qafzeh hominins - Wikipedia

    en.wikipedia.org/wiki/Skhul_and_Qafzeh_hominins

    The Skhul and Qafzeh hominins or Qafzeh–Skhul early modern humans [1] are hominin fossils discovered in Es-Skhul and Qafzeh caves in Israel. They are today classified as Homo sapiens, among the earliest of their species in Eurasia. Skhul Cave is on the slopes of Mount Carmel; Qafzeh Cave is a rockshelter near Nazareth in Lower Galilee.

  5. Rhizolith - Wikipedia

    en.wikipedia.org/wiki/Rhizolith

    Rhizoliths are organosedimentary structures formed in soils or fossil soils by plant roots. They include root moulds, casts, and tubules, root petrifactions , and rhizocretions. Rhizoliths, and other distinctive modifications of carbonate soil texture by plant roots, are important for identifying paleosols in the post- Silurian geologic record.

    Bust of the paleontologist Georges Cuvier (left) and a cast skeleton of Palaeotherium magnum (named by Cuvier in 1804, right), Cuvier Museum of Montbéliard. Paleontology (/ ˌ p eɪ l i ɒ n ˈ t ɒ l ə dʒ i, ˌ p æ l i-,-ən-/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -⁠ən-), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to the start of the ...

  7. Trilobite - Wikipedia

    en.wikipedia.org/wiki/Trilobite

    Many of the Diplichnites fossils are believed to be traces made by trilobites walking on the sediment surface. [35] Care must be taken as similar trace fossils are recorded in freshwater [36] and post-Paleozoic deposits, [37] representing non-trilobite origins. Trilobite fossils are found worldwide, with thousands of known species.

  8. Paleontology - Wikipedia

    en.wikipedia.org/wiki/Paleontology

    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.

  9. Dueling Dinosaurs - Wikipedia

    en.wikipedia.org/wiki/Dueling_Dinosaurs

    Cast of a skin impression from the foot of the tyrannosaur. The specimen is considered one of the best-preserved and most complete fossils of both species of Triceratops and over 98% completeness of a Tyrannosaurus [17] and contains skin impressions, and potentially internal organs, stomach contents, and proteins. [3] [5]
