NUMKey: An identification database program for B-forms of Nummulites species (foraminifera; Paleogene) for Windows and Android operating systems

Abstract

Nummulites is an index taxon for the Paleogene period. Because of the numerous species of this genus, it takes some time to identify and describe the species. Thus, NUMKey has been developed as a tool to provide convenience for paleontologist in definition of Nummulites species. This program has been written for a Windows operating systems with Visual Basic and an Android mobile systems with Java (Eclipse) to determine microspheric specimens of 138 Nummulites species. Important physical characteristics for identifying the species-such as granulation, shape of test, septal filaments, shape of septa at adult stage, H-L ratio of a chamber and central knob-have been entered into the database. Since the program includes an open-source code, this aspect permits the modifications both on the source code and the database.
