A replacement name for †Psammorhynchus Grande & Hilton, 2006 (Actinopterygii, Acipenseriformes, Acipenseridae)

  • Lance Grande (a1) and Eric J. Hilton (a2)

In 2006, we (Grande & Hilton, 2006) described a well-preserved fossil sturgeon (Acipenseridae) from the Late Cretaceous of Montana and proposed the name †Psammorhynchus longipinnis Grande & Hilton for the new species. Through accidental discovery of an on-line taxonomic database of flatworms (Tyler et al., 2006) and subsequent investigation, we recently discovered that the genus-group name is preoccupied by Psammorhynchus Meixner, 1938 in Platyhelminthes (“Turbellaria”). Therefore, under Article 60 of the International Code of Zoological Nomenclature (ICZN, 1999), a replacement name is required for the junior homonym †Psammorhynchus Grande and Hilton.
