Palaeoctopus is an extinct genus of octopuses that lived during the Late Cretaceous. It contains one valid species, P. newboldi, which has been found in Lebanon.
Taxonomy
[edit]Calais newboldi was named by Henry B. Woodward in 1896 for a nearly-complete specimen from the Sahel Alma lagerstätte of Lebanon.[2] However, that genus name was preoccupied by the beetle Calais.[3] Woodward named Palaeoctopus as a replacement later the same year.[1] Embrik Strand proposed the alternate replacement name Calaita in 1928.[4]
Beloteuthis libanotica was named by Adolf Naef in 1922 for a supposed teudopsid gladius from Sahel Alma.[6] It was moved to a new genus, Parateudopsis, by Theo Engeser and Joachim Reitner in 1986.[5] The specimen was eventually reidentified as an isolated gladius vestige of P. newboldi.[7]
A second species, P. pelagicus, was named by Dirk Fuchs and colleagues in 2008 for an alleged gladius vestige from the Vallecillo lagerstätte of Mexico.[8] It was subsequently revealed to be a gular plate from a coelacanth, possibly a juvenile Megalocoelacanthus.[9]
