Talk:Palaeosauriscus

Palaeosauriscus should be merged with Paleosaurus in order to create a taxobox for Paleosaurus and because of the note that Palaeosauriscus is now synonymous with Paleosaurus. 72.194.116.63 20:07, 7 April 2007 (UTC) Vahe Demirjian 7 April 2007 14.07

Merge the page Palaeosauriscus with Paleosaurus. Palaeosauriscus is actually a junior synonym of Paleosaurus. Moreover, Palaeosaurus sternbergi was renamed Sphenosaurus by Hermann von Meyer in 1847, and Palaeosaurus diagnosticus is now a junior synonym of Efraasia minor (Yates, 2003). Finally, Palaeosaurus fraserianus is likely to be an indeterminate archosauriform.

 * According to what I've read, only one of the species assigned to Paleosauriscus is "Paleosaurus". Since there are three species, I think it would be inappropriate to merge it into an article which only deals with Paleosaurus. Firsfron of Ronchester  05:23, 24 October 2009 (UTC)

No. Palaeosaurus sternbergi was renamed Sphenosaurus von Meyer, 1847, the original name (Palaeosaurus Fitzinger, 1840) being pre-occupied by Palaeosaurus Geoffrey Saint-Hillaire, 1833 (see http://dml.cmnh.org/2000Apr/msg00666.html, http://dml.cmnh.org/2000Apr/msg00668.html, http://dml.cmnh.org/2002Apr/msg00630.html, http://dml.cmnh.org/2002Aug/msg00273.html). Palaeosaurus fraserianus is based on a tooth and has been considered an indeterminate sauropodomorph by Galton and Upchurch (2004) but may be an indeterminate archosauriform. Palaeosauriscus was a replacement name for Palaeosaurus Riley and Stutchbury, 1836 by Kuhn (1959). Paleosaurus cylindrodon was designated the type species of Palaeosauriscus by Kuhn (1965). Additionally, Palaeosaurus diagnosticus is a synonym of Efraasia minor (Yates, 2003). See http://www.ville-ge.ch/mhng/paleo/paleo-pdf/26-2/pal-26-2-07-1.pdf and http://www.ville-ge.ch/mhng/paleo/paleo-pdf/26-2/pal-26-2-07-2.pdf for information on Palaeosauriscus, which is why the Palaeosauriscus page should be merged with the Paleosaurus page.
