Reassessment of ‘Chilotherium wegneri’ (Mammalia, Rhinocerotidae) from the late Miocene of Samos (Greece) and the European record of Chilotherium

“…The mandibular symphysis is, however, almost perfectly preserved and is very massive, reaches posterior the p3s and the incisors are widely separated from each other. These features clearly separate C. schlosseri from any non-chilothere rhino; however, within the genus Chilotherium these features are rather common and relatively uniform, not allowing a specific identification of a mandible (e.g., Kampouridis et al, 2022b). Nonetheless, the features of the skull and upper dentition allow the distinction of C. schlosseri from all other chilothere species.…”

“…Another feature that Weber (1905) pointed out in Aceratherium schlosseri is the big minimal distance between the parietal crests, which is 90 mm in the lectotype. This was also discussed by Kampouridis et al (2022b) who considered a minimal distance between the parietal crests of over 70 mm as a diagnostic feature of C. schlosseri that is not seen in other chilotheres (Table 2). In GPIH 3015 this distance is 89 mm, thus very close to the lectotype of Aceratherium schlosseri.…”

“…75.3.3). The type material of both Aceratherium schlosseri and Aceratherium samium, including all material described by Weber (1905), was formerly housed in the BSPG, but cannot be relocated and it is believed that it was destroyed in the Second World War (Giaourtsakis, 2003(Giaourtsakis, , 2022Kampouridis et al, 2022b), during the bombing of Munich by the Allied Royal Air Force on April 24, 1944 (Nothdurft & Smith, 2002), thus meeting the condition of ICZN Art. 75.3.4.…”

“…The problematic taxonomic status of Aceratherium kiliasi has been discussed by several authors (Athanassiou et al, 2014;Fortelius et al, 2003;Geraads & Spassov, 2009;Giaourtsakis, 2003;Heissig, 1996Heissig, , 1999Kampouridis et al, 2022b). It was originally erected by Geraads and Koufos (1990) for aceratheriine material from the Vallesian locality Pentalophos-1 in Northern Greece.…”
