Chironstenotes synonymies

Place Chironstenotes sternbergi (Cracraft, 1971) in the synonymy of Chironstenotes pergracilis, because this species is definitely referrable to C. pergracilis (Currie, 2005). Also, Sues (1997) showed Ornithomimus elegans to be a species of Chirostenotes. Because Sues (1997) noted similarities of C. sternbergi to C. elegans, he placed C. sternbergi in the synonymy of C. elegans. Currie & Russell (1988) suggested the possible synonymy of Caenagnathus with Chirostenotes, a hypothesis confirmed by Sues (1997). They went further by proposing that C. elegans and C. pergracilis may represent two sexes of the same species.

"I propose returning Ornithomimus elegans to Elmisaurus." Unfortunately, this is not JVP and I am not the peer review comittee. Better publish this elsewhere ;) Dinoguy2 06:01, 7 March 2007 (UTC)

Split page

Senter (2007) in his study "A new look at the phylogeny of coelurosauria" found Caenagnathus and Chirostenotes not congeneric and not even closely related. So says tha phylogeny section of the article of wikipedia "oviraptorosauria": but the page contradicts itself. And family Caenagnathidae is found to be paraphyletic too: i suggest a revision of pages related to oviraptorosaurs —Preceding unsigned comment added by Brisio (talk • contribs) 09:56, 21 November 2009 (UTC)

I've heard of that, too. I don't know how widely accepted it is, however. 209.121.124.49 (talk) 01:34, 26 November 2009 (UTC)

Definitely need to wait on this. It was the result of a phylo analysis but was not even commented upon and would represent a pretty major upheaval of oviraptorid taxonomy. Wait for a paper that attempts to resurrect Caenagnathus, or at least a second analysis that finds that same thing and maybe notes how unorthodox it is...

Chirostenotes elegans no more

Longrich et. al. (2013) subsume Ornithomimus elegans in the new genus Leptorhynchos and describe a new species of Leptorhynchos from Big Bend National Park in Texas. Looks like elegans isn't Chirostenotes or Elmisaurus but instead its own thing.

I don't have the paper yet, anybody know which is the type species, L. elegans or the new one? MMartyniuk (talk) 12:00, 24 April 2013 (UTC)

Longrich et. al. (2013) have published a corrigendum to the original description of Leptorhynchus gaddisi clarifying that Leptorhynchos gaddisi is the type species of Leptorhynchos. This means that "Ornithomimus" elegans is a referred species of Leptorhynchos, at least for now (as ROM 781 doesn't overlap with the holotype of L. gaddisi.

New name for Hell Creek caenagnathid

The Hell Creek caenagnathid has been given its own genus and species name, Anzu wyliei (Lamanna et. al. 2014). Since the description of Anzu removes the last of the putative records of Chirostenotes from post-Juidithian strata, the images of Anzu (including CM 78000).

Specimen

• Anyone know where that leaves this specimen, which is apparently labelled Chirostenotes pergracilis at the Royal Tyrrell Museum? FunkMonk (talk) 10:57, 20 March 2014 (UTC)

I don't know of any ceanagnathid specimen known from that much skeletal material other than Anzu, but it would be good to double check. Might be something undescribed. Dinoguy2 (talk) 11:48, 20 March 2014 (UTC)

Might it be Apatoraptor?[1] The elements seem to match, but I haven't seen a photo. FunkMonk (talk) 09:12, 13 April 2016 (UTC)

I see MWAK expanded the Dutch article, perhaps he knows? FunkMonk (talk) 09:35, 13 April 2016 (UTC)

It is indeed Apatoraptor :o). Good that you remembered! (I didn't...).--MWAK (talk) 12:28, 13 April 2016 (UTC)

Great! I have a whole Commons category[2] full of unnamed dinosaurs waiting for description... FunkMonk (talk) 12:37, 13 April 2016 (UTC)

The work is never done. Here's another one: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0150529 ;o).--MWAK (talk) 05:28, 14 April 2016 (UTC)

I wonder how an article about such a creature would looks? FunkMonk (talk) 09:30, 14 April 2016 (UTC)

In principle like any other article. We just would have to name it "CPC 274", which is a bit awkward. If you dare to create it, I'll flesh it out. After all, as we both know, the text is just there to provide room for the images ;o).--MWAK (talk) 13:08, 14 April 2016 (UTC)

Hehe, what to do if more specimens are referred to it, but it is yet unnamed? FunkMonk (talk) 08:28, 15 April 2016 (UTC)

Well, if it has no name, how can specimens be referred to it? ;o) But I see what you mean. We might than add a chapter "Additional Coahuila centrosaurine material". Or, alternatively we could rename the article "Coahuila Centrosaurinae" :o).--MWAK (talk) 12:46, 15 April 2016 (UTC)
