Amber is the fossilized resin of trees. It is generally a golden brown color, very low density, and may or may not contain fossil inclusions such as trapped plant material, insects, or other small animals.

The fascinating field of reconstructing past life is augmented by the contributions of talented artists who take up the challenge of determining how that life might looked. This category is for any website dealing with paleontology-themed art.

The study of paleontology can be broken down in a number of ways. One way to study past life is to examine specific intervals of the earth's past. This category is for any website that deals with the study of these intervals.

This category is for website dealing with professional paleontology meetings. Please include information about where and when the meeting will take place in your description.

Online paleontology databases are the newest way to share paleontological information. Included in this category are a variety of databases dealing with the taxonomy, ecology, and geological ranges of ancient organisms.

This category is for websites that list links to paleontology internet resources.

This category is for any website dealing with the teaching of paleontology as an academic study.

Most animals and plants that ever lived died out long before the present. The fossil record reveals that there are several periods of time in the earth's past when the extinction rate was very high (e.g., at the Cretaceous/Tertiary boundary, and the Permian/Triassic boundary) - causing mass extinctions of a large percentage of the species. This category contains sites dealing with the subjects of extinction and mass extinctions in the fossil record.

Some fossil localities have become famous because of their exceptional fossil preservation. Sites dealing with these paleontological treasures can be found in this category.

Collecting fossils is an enjoyable hobby for many enthusiasts. This category is for any website dealing with recreational fossil collecting.

This category is for websites dealing with the study of the human history of the study of paleontology.

The most common animal macrofossils in the rock record are the reamins of animals without backbones - the invertebrates. This category is for any website dealing with the study of individual invertebrate fossil groups.

Micropaleontology is the study of microscopic remains of ancient life. Such marine micro-organisms as diatoms, dinoflagellates, foraminifera, silicoflagellates, and radiolarians all have very good fossil record. Plant pollen also has an extensive microfossil record.

This category is for professional and amateur paleontological organizations which do not themselves conduct scientific research but aim to spread information about such research. They organize meetings, publish journals and provide research grants for scientists in the field.

Paleobotany is the branch of paleontology dealing with the recovery and identification of plant remains from geological contexts, their use for the biological reconstruction of past environments and the understanding of the evolution of plants. Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photosynthetic algae or seaweeds.

This category is for websites dealing with specific professional paleontologists.

Websites offering paleontological supplies, equipment, models, and specimens.

Publications (books, magazines, and journals) dealing with paleontological subjects.

This category is for any website which deals with fossils or paleontology of a specific area or region.

The sites in this category contain information about where to get money for paleontological research.

Most research activities will either occur in academic departments or in research institutes (which may either be in universities or external). Both of these are included in this category.

Taphonomy is the study of the post-mortem history of organic remains. Taphonomic processes can be constructive (as in those processes that lead to fossilization), or more commonly destructive. Understanding taphonomy is essential to the proper interpretation of fossil deposits.

Trace fossils, or ichnofossils, are the preserved evidence of animals activity found in the rock record. They range from dinosaur footprints to worm burrows to root traces. This category is for any website dealing with the study of trace fossils.

Vertebrate paleontology is the study of ancient animals with backbones: fish, amphibians, reptiles, mammals, birds.
