Anomoeodus pauciseriale n. sp. (Neopterygii, Pycnodontiformes) from the White Chalk Formation (Upper Cretaceous) of Sussex, South England

The new pycnodont fishAnomoeodus pauciseriale is described. The single specimen consists of associated but disarticulated skeletal remains including the paired prearticulars, some skull elements, remains of the pectoral girdle and the vertebral column. It comes from the White Chalk Formation (Upper Cretaceous) of East Sussex near Lewes, England. The precise stratigraphic age and locality are not known. The specific identification is based on characters of the prearticular dentitions because the other skeletal remains are not diagnostic. In contrast to other species ofAnomoeodus, the new species is characterised by a combination of rather short prearticular dentitions with only four tooth rows, a comparable low number of medial teeth, and the absence of intercalated teeth between tooth rows.
