Whenever possible, authors are advised to deposit type specimens in national or international public museums or collections. Authors are also advised to request registration numbers of deposited material in advance of the acceptance of papers to avoid unnecessary delay of publication. Some countries (e.g. Australia) require that primary type specimens be deposited in collections of the country of origin; authors are advised to take this into consideration. In this way, your materials (micro and macrofossils as well as all kind of rock samples) are welcome to deposit in the "Geological Survey of Iran, NE territory, Geoscience Museum" and give you the repository system number in order to use in scientific papers.
