Paraphyletic Rhamphorhynchoidea

"Rhamphorhynchoidea" is regarded by virtually all pterosaur workers as ployphyletic and should not be used in pterosaur classification since it basically means any pterosaur that is not a rhamphorhynchoid. Apatomerus 16:37, 7 January 2007 (UTC)[reply]

Really, polypheltic? i've never heard that. I know it's universally seen as paraphyletic, but this is stated in the text (no doubt you've read the article). Contrary to popular belief, paraphyletic groups are not invalid under all classification schemes, only phylogenetic ones. Note that there are different sections for classifiaction and phylogeny.

Gah! Paraphyletic rather, I got the two mixed up, but I still feel that it should not be used. The term is becoming abandoned by most workers. Yes, I did read the article, and I feel that it is far too favourable of an outdated scheme, only making a brief mention at the end of the classification used by virtually all pterosaur workers while attributing a classification that uses "rhamphorhynchoidea" to Unwin, who never has used the term as far as I can recall. I suppose it boils down to Linnean vs. cladistics, and I really want to see the Linnean system done away with as it does not reflect evolutionary relations. Apatomerus 22:20, 11 January 2007 (UTC)[reply]

I prefer using both in a complimentary manner. Unwin does use Rhapmhporhynchoidea in his popular book Pterosaurs: From Deep Time, actually. It's a handy, even if informal, term to refer to basal pterosaurs. Dinoguy2 22:50, 11 January 2007 (UTC)[reply]

Well, if one wishes to discuss the these critters, there's really no other way. Strict phylogenetic naming won't let us define them (there's no crown group, and the stem contains everything more related to pterosaurs than to dinos (possibly, the tree isn't entirely clear at this point). Petter Bøckman (talk) 13:08, 21 June 2011 (UTC)[reply]

They can be perfectly defined, and this definition produces a perfect name for them: non-pterodactyloid pterosaurs :o).--MWAK (talk) 19:18, 26 July 2015 (UTC)[reply]
