Form taxon (botany) - It is often not possible to associate the wood, leaf, flower, fruit and pollen of a fossil plant with each other, as fossil plants are usually found as disarticulated parts, and the individual parts are often insuffucient for identification, particular for older material which is less closely related to modern representatives, and may be less well preserved. Consequently paleobotanists used form taxa to name the fossil parts of plants where identification with a complete plant, whether living, or a reconstructed fossil, is not possible.
Conspecificity - Conspecificity is a concept in biology. Two or more individual organisms, populations, or taxa are termed conspecific if they belong to the same species.
Extinction - In biology and ecology, extinction is the cessation of existence of a species or group of taxa, reducing biodiversity. The moment of extinction is generally considered to be the death of the last individual of that species (although the capacity to breed and recover may have been lost before this point).
