A "chirotype" is a biological specimen, such as an animal, plant or fungus, that is used preliminarily in an unpublished scientific work as an example of the general kind of organism it is. Once the document describing the organism is published, the chirotype becomes a true type specimen.
True type specimens are used to describe the anatomy and traits expected to be seen in that general kind of organism. Types help define the organism in scientific literature. Chirotypes are distinguished from true types to allow for the fixing of mistakes and other changes during the publication process. Scientific papers undergo peer review before publication so that other scientists can examine if the research is valid.
