fossilization |
to convert into a fossil; replace organic with mineral substances in the remains of an organism |
|
|
Carbonization |
convert into carbon |
|
|
Petrifaction |
the process by which organic matter exposed to minerals over a long period is turned into a stony substance. |
|
|
Tectonic activity |
when two tectonic plates crush together or drift or slide against eachother |
|
|
Microfossil |
A fossil only visible with a microscope |
|
|
Gastroliths |
a small stone swallowed by a bird, reptile, or fish, to aid digestion in the gizzard. |
|
|
Coprolites |
Fossilized dung |
|
|
Transitional fossil |
any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. |
|
|
Archaeopteryx |
Oldest fossil bird |
|
|
Amber |
hard translucent fossilized resin produced by extinct coniferous trees of the Tertiary period, typically yellowish in color. |
|
|
Replacement Fossilization |
Most organisms become fossils when they're changed through various other means. ... In another fossilization process, called replacement, the minerals in groundwater replace the minerals that make up the bodily remains after the water completely dissolves the original hard parts of the organism. |
|
|
Zoolite |
Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. ... Based on this, he called the material zeolite, from the Greek ζέω (zéō), meaning "to boil" and λίθος (líthos), meaning "stone". Zeolites occur naturally but are also produced industrially on a large scale. |
|
|
Scolecodont |
A scolecodont is the jaw of a polychaete annelid, a common type of fossil-producing segmented worm useful in invertebrate paleontology. Scolecodonts are common and diverse microfossils, which range from the Cambrian period (around half a billion years ago at the start of the Paleozoic era) to the present. |
|
|
Cast |
shaped |
|
|
concentric |
of or denoting circles, arcs, or other shapes that share the same center, the larger often completely surrounding the smaller. |
|
|
paleontology |
the branch of science concerned with fossil animals and plants.
|
|
|
Igneous Inclusions |
A xenolith (Ancient Greek: "foreign rock") is a rock fragment which becomes enveloped in a larger rock during the latter's development and solidification. In geology, the term xenolith is almost exclusively used to describe inclusions in igneous rock during magma emplacement and eruption. |
|
|
Lithification |
Lithification (from the Ancient Greek word lithos meaning 'rock' and the Latin-derived suffix -ific) is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock. Essentially, lithification is a process of porosity destruction through compaction and cementation
|
|
|
Remineralization |
In biogeochemistry, remineralisation (UK, US Spelling: remineralization) refers to the breakdown or transformation of organic matter (those molecules derived from a biological source) into its simplest inorganic forms |
|
|
Ichnofossil |
A trace fossil, also called an ichnofossil (pronunciation: /ˈɪknoʊfɒsᵻl/; Greek: ιχνος ikhnos "trace, track"), is a geological record of biological activity. |
|
|
Mold |
a hollow container used to give shape to molten or hot liquid material (such as wax or metal) when it cools and hardens. |
|
|
Boring & Burrows |
to create a hole using a tool of some sort
|
|
|
Transitional fossil |
A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. |
|
|
fossil beds |
The hardened remains or imprint of a plant or animal that lived long ago. Fossils are often found in layers of sedimentary rock and along the beds of rivers that flow through them. ... Petroleum, coal, and natural gas, which are derived from the accumulated remains of ancient plants and animals, are called fossil fuels. |
|
|
organisms |
an individual animal, plant, or single-celled life form. |
