D e s c r i p t i o n a n d c o m p a r i s o n. The preserved fossil jaw fragments bear all the morphological traits typical of Rhinolophus species and morphologically correspond to R. delphinensis already described in detail (see Ziegler 2003: 451–456). As was reported above many fossil Rhinolophus species known from Europe have significant differences in size (see also Ziegler 2003: 456, tab. 2). The middle-sized Rhinolophus from Petersbuch 2, Erkertshofen 1 and Erkertshofen 2 ( Tab. 4) is significantly smaller than R. aff. lemanensis ( Tab. 3) and larger than other small forms of Rhinolophus from Petersbuch 2, Erkertshofen 1 and Erkertshofen 2 ( Tab. 4). The Rhinolophus from Petersbuch 2, Erkertshofen 1 and Erkertshofen 2 compares well in morphology with R. delphinensis from both the type locality La Grive 7 (see Text-fig. 2g –h ; Gaillard 1899; for more detailed measurements see Mein 1964) and the middle Miocene sites of Petersbuch 6, 10, 18 and 31 ( Ziegler 2003: fig. 1(1–6)). However, there are only a few fossils of this middle-sized Rhinolophus from Petersbuch 2, Erkertshofen 1 and Erkertshofen 2 and we assign them to R. cf. delphinensis. The other small-sized forms of Rhinolophus from Petersbuch 2, Erkertshofen 1 and Erkertshofen 2 are significantly smaller than the form of R. cf. delphinensis (see below; Tab. 4).
