Name

Was Baragwanath a botanist who identified it and was it known before 1935?--Felix Folio Secundus (talk) 07:58, 13 August 2009 (UTC)

global dispersal of spores ?

c.420Ma, in the late Silurian, the fossil sites in (archaic) Canada were separated, from the fossil sites in China & Australia, by thousands of miles of equatorial ocean. Does the global presence, of similar species, imply the presence of "Silurian trade winds", which would have carried plant spores, over oceans, from continent to continent? 66.235.38.214 (talk) 12:31, 24 October 2012 (UTC)

If so, then perhaps other places, which were then at similar latitudes, e.g. northern Scandinavia, may also bear Baragwanathia fossils ? 66.235.38.214 (talk) 12:36, 24 October 2012 (UTC)

Melbourne Museum "model" image?

Really? I looked at this image and the description, and I found it hard to believe that it could be a model - it is far too finely detailed and executed. So I went looking, trying to find some discussion about such a fabulous creation at the Melbourne Museum website, or anywhere else. I found nothing. However, I did find this image of a current living plant: https://wikivisually.com/wiki/File:Lycopodium_phlegmaria_%28fabooj%29.jpg#file It looks pretty much identical to the plant in the Baragwanathia "model" image. So, I am suspecting that the "model" is actually a living Lycopodium phlegmaria (or, based on a search and the complaint attached to that file page, a living Lycopodium sqarrosum) presented at the museum as a modern example of something similar to the Devonian plant. I suggest this be investigated...(talk) 04:13, 20 December 2019 (UTC)JustSomeWikiReader

I agree. There's an image here, which is notably different; in particular the leaves (microphylls) are much thinner and shorter (hardly longer than the diameter of the stem). I've removed the image. Peter coxhead (talk) 11:47, 20 December 2019 (UTC)

Now found the original. See here, and then click on the second small image, which will take you to the source of the image placed here. The text makes clear that this is Huperzia squarrosa, a synonym for Phlegmariurus squarrosus. Peter coxhead (talk) 11:58, 20 December 2019 (UTC)

The file has now been renamed commons:File:Phlegmarius squarrosus Melbourne Museum.jpg and I've changed the description accordingly. Thanks again to 2001:56A:F0E9:9B00:6D65:DBCA:8828:2997 for spotting this! Peter coxhead (talk) 11:15, 21 December 2019 (UTC)

are there really securely dated Silurian fossils?

I noticed that the main finds in Australia, that were thought to be of Silurian age, were later dated as Devoninan, thanks to a longer range of certain graphtolites. The only source I have not been able to check is the article of Richards from 2000, which according to its title deals with liver mosses. The reference also points to the Yea Floral Fossil site, but that is 415 MYA. So it seems that everybody is continuing to use these outdated time references, but perhaps somebody who has access to an academic search machine can check the literature to see if there are any independent secure dates from the Silurian and if so, add it to this article and if not, correct the age given here.
