Indigenous fossil legends also frequently show motifs resembling major themes in scientific paleontology like deep time, extinction, change over time and relationships between different life forms. [3] Fossils have been used by Native Americans for evidence about the past, healing, personal protection, and trade. [4]
Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. [59] 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.
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.

The discovery of a well-preserved fossil is helping researchers learn more about an iconic Jurassic-period species. The plesiosaur, considered a successful marine predatory ancient species, may ...
An intriguing arthropod ancestor. The 3D scans revealed two nearly complete specimens of Arthropleura that lived 300 million years ago. Both fossilized animals still had most of their legs, and ...
The fossil record and faunal succession form the basis of the science of biostratigraphy or determining the age of rocks based on embedded fossils. For the first 150 years of geology , biostratigraphy and superposition were the only means for determining the relative age of rocks.
Fossil remains of Hyracotherium show it to have differed from the modern horse in three important respects: it was a small animal (the size of a fox), lightly built and adapted for running; the limbs were short and slender, and the feet elongated so that the digits were almost vertical, with four digits in the forelimbs and three digits in the ...
Living among a small band of Neanderthals in what is now eastern Spain was a child, perhaps 6 years old, with Down syndrome, as shown in a remarkable fossil preserving traits in the inner ear ...
