† Pandion pannonicus Kessler, 2018 Location and age: Máriahalom; Lower Miocene (MN16). Material: phalanx ungualis, digit pedis II (Figure 2 /3). Dimensions (mm): A—19.3, B—9.9, C—3.50, D—5.20, E—4.8. Description: This fossil, like the previously identified bones of † Pandion pannonicus, is smaller than those of the currently known osprey. The tuberculum extensorium is oblique with a blunt end; the cotyla articularis has an asymmetrical outline; the neck of the tuberculum flexorium is short, the lower part is convex in the middle; the corpus phalangis is wide and curved and the apex phalangis is damaged. The dimensions of the fossil are 80% of those of the extant species. It is similar in size and shape to the holotype example described. Comparative material: Pandion haliaetus (2010.222.1); Pandion pannonicus Kessler, 2018 (uncatalogued). This material is catalogued, number:VER 2021. 72; the bones belong to the collection of the Hungarian Museum of Natural History.
