This diagram image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Machoires de koala avec dents.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: découpe du koala. The original can be viewed here: Pungdjurens tänder.png: . Modifications made by Saint amand.

This image was first published in the 1st (1876–1899), 2nd (1904–1926) or 3rd (1923–1937) edition of Nordisk familjebok. The copyrights for that book have expired and this image is in the public domain, because images had no named authors and the book was published more than 70 years ago.

This image (or other media file) is in the public domain because its copyright has expired and its author is anonymous. This applies to the European Union and those countries with a copyright term of 70 years after the work was made available to the public and the author never disclosed their identity. Important: Always mention where the image comes from, as far as possible, and make sure the author never claimed authorship. Note: In Germany and possibly other countries, certain anonymous works published before July 1, 1995 are copyrighted until 70 years after the death of the author. See Übergangsrecht. Please use this template only if the author never claimed authorship or their authorship never became public in any other way. If the work is anonymous or pseudonymous (e.g., published only under a corporate or organization's name), use this template for images published more than 70 years ago. For a work made available to the public in the United Kingdom, please use Template:PD-UK-unknown instead.
