The fossil mammal fauna of the Gračanica coal mine in central Bosnia and Herzegovina includes dental remains of Anisodon (Perissodactyla, Chalicotheriidae, Chalicotheriinae). These teeth most closely resemble those of Anisodon grande from Sansan (France, MN6) and Neudorf an der March (Slovakia, MN6), and are tentatively referred to that species. Anisodon is first known in Europe from the Loire Basin (France), which has been dated as MN5. Given that the Gračanica fauna is considered to be MN5 or earliest MN6 (Langhian), the Gračanica chalicothere represents one of the earlier known finds of both the Chalicotheriinae and Anisodon in Europe. The first known members of the Chalicotheriinae are from the earliest Miocene of Asia. By the middle Miocene, Anisodon had appeared and is known from Asia and Europe, to which it had recently immigrated.

中新世中部地区Gračanica（Bugojno盆地，Gornji Vakuf，波斯尼亚和黑塞哥维那）的Anisodon（Perissodactyla，Chalicotheriinae）

波斯尼亚和黑塞哥维那中部Gračanica煤矿的化石哺乳动物区系包括Anisodon（Perissodactyla，Chalicotheriidae，Chalicotheriinae）的牙齿遗骸。这些牙齿最类似于Sansan（法国，MN6）和March der Neudorf（斯洛伐克，MN6）的Anisodon grande的牙齿，并暂定为该物种。Anisodon在欧洲最早是从法国的卢瓦尔河盆地（Loire Basin，法国）得知的，其日期为MN5。考虑到Gračanica动物区系被认为是MN5或最早的MN6（朗根），Gračanicachalicothere代表了Chalicotheriinae和Anisodon的较早发现的动物之一在欧洲。Chalicotheriinae的第一个已知成员来自亚洲最早的中新世。在中新世中期，Anisodon出现了，并在亚洲和欧洲广为人知，最近已移居该地。
