On the status of Pecten burdigalensis Lamarck var. polonica Pusch, 1837 (Bivalvia: Pectinidae)

Studencka Barbara

Vol. 74, no. 1

art. no. e1

The well-known Pleuronectia badensis Fontannes, 1882 (currently classified as Cristatopecten cristatus badense) is declared as a nomen protectum against the older synonym Pecten burdigalensis var. polonica Pusch, 1837 considered a nomen oblitum. It ranges from the early to the late Miocene (Burdigalian–Messinian) of the NE Atlantic and Mediterranean. In the Central Paratethys it appeared in the early Miocene (Karpatian, correlating with the latest Burdigalian) and became extinct in the middle Miocene (Late Badenian, correlating with the early Serravallian). In Poland – the northernmost part of Central Paratethys – the occurrence of this taxon is limited to the late Early Badenian (late Langhian).

The Order Clupeiformes Bleeker, 1859 comprises herrings, anchovies, sprats, sardines, and shads. The fossil record of this group is rich within the Paratethys. Here we describe a new clupeiform fish, †Sanalosa janulosa gen. et sp. nov., from the Lower Oligocene of the Carpathian Basin, Poland. This new genus has a unique combination of characters (lower jaw articulation located under the posterior part of the orbit; abdominal scutes well developed with 3 to 5 in the gular region, 11–14 prepelvic scutes associated with ribs, 11–12 postpelvic scutes; several striae on the frontals; an opercle with 6–12 thin radial ridges; a horizontal ramus of the preopercle shorter than the vertical one; 42–44 vertebrae; 8–10 supraneurals; a dorsal fin with 18–22 rays, and an anal fin with 21–23 rays), supporting recognition of a new genus and species within the Family Alosidae Svetovidov, 1952. Similarities and differences between fossil and extant genera of the Clupeiformes are discussed to shed more light on their relationship. Moreover, the palaeobiogeography, diversity and distribution of Oligocene clupeiform fishes in the Paratethys are presented and discussed.
