Talk:Charnia

message: Someone has put a  template on the article page. I don't see what could be put in a taxobox, other than (rather tentatively) Animalia. -- Donald Albury 00:52, 9 March 2007 (UTC)

message: I seem to recall Narbonne mentioning longer fossils from the Avalon assemblage, so have weakened this statement — I'm not sure if these findings have been published yet but if they have, it would be worth tracking them down and amending this article accordingly.

thread_title:  Longest fossil? 

message: Does/did Charnia have a holdfast, and how was it suspected to be oriented in life?--Mr Fink (talk) 04:03, 25 August 2008 (UTC)
replies: text: One of the cited sources, Antcliffe and Brasier, states that Charnia had a holdfast. Orientation would be a matter of interpretation, and I don't see it addressed in the article or the sources I checked. There are some problems with the article; one of the citations is borked, and th narrative is not very well organized. Maybe I'll come back to this when I have a little more time. -- Donald Albury 14:12, 25 August 2008 (UTC)
replies: text: As I recall, It was traditionally interpreted as erect, but others suspect it lay on, or perhaps even in, the sediment surface.  There's a spectacular slab at Newfoundland point where loads of Charniodiscus specimens are aligned with the current, but the Charnia seem blissfully unaware of the way the current was flowing - I'm sure a Narbonne paper somewhere will detail it if you poke around.  That suggests it wasn't erect.   I can't recall seeing any fossils with attached holdfasts, so I would check exactly what Brasier & Antcliffe have to say.

replies: text: I find this, "true charniomorph fronds from the UK., Canada and Australia (Brasier & Antcliffe 2004; Narbonne 2004) show the following diagnostic features, absent in Stromatoveris (compare Figs 1b and 2): a glide plane of symmetry; similar upper and lower surfaces; a holdfast", in Charnia and sea pens are poles apart. That link shows the article for free/no registration, so perhaps we should substitute it for the link now used in the citation in the article. -- Donald Albury 22:37, 26 August 2008 (UTC)
thread_title: 2 Questions

message: Roger Mason, Helen Boynton and Trevor Ford all now accept that the holotype specimen of Charnia masoni was seen a year before Roger's "discovery", in 1956 by then schoolgirl Tina Batty (now Tina Negus). Although she had no doubt that it was a Precambrian fossil, she was unable to convince her Geography teacher, and did not know where to report the find. Roger Mason not only noticed the fossil and correctly knew its importance, but was able to contact Trevor Ford who was taken to view the specimen itself. the rest, as they say, is history!  —Preceding unsigned comment added by Tina negus (talk • contribs) 14:46, 14 February 2009 (UTC)
replies: text: Unfortunately, before this fact can be added to the article, it needs to be attributed to a reliable, published source.  If you can find one, we'll happily update the article accordingly!

Thanks Martin, I have now edited the ref as I did not know Roger until very recently!  —Preceding unsigned comment added by Tina negus (talk • contribs) 18:58, 15 February 2009 (UTC)
