Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the fossil record. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good ...
A fossil word is a word that is broadly obsolete but remains in current use due to its presence within an idiom or phrase. [ 1 ] [ 2 ] An example for a word sense is 'ado' in 'much ado'. An example for a phrase is ' in point ' (relevant), which is retained in the larger phrases ' case in point ' (also 'case on point' in the legal context) and ...
Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, "zone fossil", is used when the fossil has all the characters stated above except wide geographical distribution; thus, they correlate the surrounding rock to a biozone rather than a specific time period.
Fossil clubs like the Delaware Valley Paleontology Club are a good place to get started. The New Jersey State Museum offers guide digs and or there is the Edelman Fossil Park of Rowan University ...
An example of an NMLA is the Rancholabrean, named after the Rancho La Brea fossil site. One of its characteristic fossils is the bison , which first appears in the Rancholabrean. [ 7 ] The committee tried to make the definitions unambiguous by providing multiple criteria such as index fossils, first and last occurrences, and the relation to a ...
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.

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.
Fossils of microbes, sea sponges, insects, sharks, early amphibians and mammals have been discovered in the rocks around the state, representing over 1 billion years of life on Earth.
