This is not to say that there are not some unique forms, there are, but the idea that they are all unique is overstepping things.\u0026quot;\u003Cbr \/\u003E\u003Cbr \/\u003E- I don\u0026#39;t think that\u0026#39;s the case. You make it sound as if it\u0026#39;s a few scattered oddballs, and mostly things that are representative of the modern fauna. But in fact, the vast majority of Ediacaran taxa have not been successfully linked to modern taxa. Kimberella is really the odd one out, and one of the rarest and least representative members of the fauna. The dominant forms are all \u0026quot;oddballs\u0026quot;.\u003Cbr \/\u003E\u003Cbr \/\u003EThere are also no sea pens; sea pens have gaps between their branches, and are considered very derived cnidarians. Their earliest fossil record (leaving Thaumaptilon aside) is the Devonian. There are no other cnidarians in the Ediacaran fauna (and certainly not earlier) - the best candidate is the very late Ediacaran Namapoikia - a possible coral. I have issues with the connection between Thaumaptilon and sea-pens, and also with the connection between Thaumaptilon and Charnia.\u003Cbr \/\u003E\u003Cbr \/\u003EBut certainly, the Ediacaran fronds don\u0026#39;t bear any resemblance to sea-pens beyond the superficial outline - no sign of gaps between the branches, no sign of the subdivision of branches that is seen in sea-pens. Indeed, Ediacaran fronds - rangeomorphs, charniids, and Pteridinium - each have their own unique anatomies; it wouldn\u0026#39;t even be correct to throw them into the same group as each other, let alone sea-pens."},"link":[{"rel":"edit","type":"application/atom+xml","href":"http:\/\/www.blogger.com\/feeds\/5517176012861550589\/6623188170636019542\/comments\/default\/5308547225699117866"},{"rel":"self","type":"application/atom+xml","href":"http:\/\/www.blogger.com\/feeds\/5517176012861550589\/6623188170636019542\/comments\/default\/5308547225699117866"},{"rel":"alternate","type":"text/html","href":"http:\/\/ediacaran.blogspot.com\/2008\/11\/introduction-to-ediacaran-fauna.html?showComment=1353303520885#c5308547225699117866","title":""}],"author":[{"name":{"$t":"Anonymous"},"email":{"$t":"noreply@blogger.com"},"gd$image":{"rel":"http://schemas.google.com/g/2005#thumbnail","width":"16","height":"16","src":"https:\/\/img1.blogblog.com\/img\/blank.gif"}}],"thr$in-reply-to":{"xmlns$thr":"http://purl.org/syndication/thread/1.0","href":"http:\/\/ediacaran.blogspot.com\/2008\/11\/introduction-to-ediacaran-fauna.html","ref":"tag:blogger.com,1999:blog-5517176012861550589.post-6623188170636019542","source":"http://www.blogger.com/feeds/5517176012861550589/posts/default/6623188170636019542","type":"text/html"},"gd$extendedProperty":[{"name":"blogger.itemClass","value":"pid-1577025230"},{"name":"blogger.displayTime","value":"November 19, 2012 at 4:38 PM"}]},{"id":{"$t":"tag:blogger.com,1999:blog-5517176012861550589.post-4249430473364775694"},"published":{"$t":"2012-10-28T10:45:08.176+11:00"},"updated":{"$t":"2012-10-28T10:45:08.176+11:00"},"title":{"type":"text","$t":"Bob,\n\non the centre right of the image, between th..."},"content":{"type":"html","$t":"Bob,\u003Cbr \/\u003E\u003Cbr \/\u003Eon the centre right of the image, between the specimen drawing and the reconstruction, is a scale bar.

Invertebrate marine pa..."},"content":{"type":"html","$t":"I am not a paleontologist.  Invertebrate marine paleontology was my original major and I got pretty far along before switching majors. (Like you said, \u0026quot;No jobs!\u0026quot;) I still keep up with the literature. I am familiar with bacterial mats\/biofilms, which have not changed much over time.  There are some considerations that you might have overlooked.  Taken together, they leave me unconvinced about your argument that the Francevillian fossils are bacterial mats.  \u003Cbr \/\u003EFirst, some minor considerations:   \u003Cbr \/\u003E(A) These fossils have not been found in other formations, but they consistently occur in several horizons within this formation.  \u003Cbr \/\u003E(B) Their age, although certainly not proof of a multicellular, oxygen-metabolizing organism, is provocative.  It occurs during the deposition of banded iron formations.   \u003Cbr \/\u003E(C) Oxygen levels 2.1 Ga were still low. Any oxygen-consuming multicellular organism at that time would probably have been quite small (1-2 cm max) and thin (a few mm), in order to acquire oxygen through its outer tissues.  It might have had peripheral folds to increase surface area for oxygen exchange.  This is far from proof, but these fossils fit that concept.   \u003Cbr \/\u003E- Those are minor considerations.  The next items are more important: \u003Cbr \/\u003E(D) Their shape, although asymmetrical, is pretty regular and recognizable, so it FITS WITHIN A LOOSE PATTERN.  This is unlike bacterial mats, which grow to fill the usable space.  \u003Cbr \/\u003E(E) Their maximum dimensions are limited.  This is true in all of the horizons where they occur.  This limited size is also unlike bacterial mats, which can grow to be quite large. \u003Cbr \/\u003E(F) A single catastrophic event could preserve a group of bacterial mats that did not have time to grow to a larger size.  That would explain a limited size range (7 - 12 mm). But these fossils are preserved in several horizons throughout the formation, yet their sizes consistently fit within the same small range.  This indicates that they had a MAXIMUM GROWTH SIZE.  That is almost a negation of bacterial mats by itself.  \u003Cbr \/\u003E(E) In other words, these fossils are too consistently small and too regularly shaped to be bacterial mats.  \u003Cbr \/\u003E(F) ALSO:  Most, but not all, fossils of bacterial mats are two-dimensional. The Francevillian fossils have a measurable thickness of up to 1 cm.  Any bacterial mats that achieve that thickness would be much larger horizontally than these fossils. The Francevillian fossils are quite small, horizontally (barely over a cm long), yet they are all three-dimensional.  Bacterial mats that size would have been just starting out and, therefore, very thin.  \u003Cbr \/\u003E(G) Bacterial mats do not thin out rapidly toward their edges.   \u003Cbr \/\u003E(H) Your excellent photos of bacterial mats show the characteristics that paleontologists look for.  These include preserved CO2 gas bubbles, wrinkles, and large tears. None of the photos of the Francevillian fossils, in any web site, show these characteristics.   \u003Cbr \/\u003E(H) The fact that they appear within different horizons of their formation, but do not occur in other formations, argues strongly against an inorganic origin.  These are not pyrite pseudofossils.\u003Cbr \/\u003E(I) There is nothing to prevent a pyrite nodule from forming in the center of these fossils.  I have found lots of pyritisized fossils that had been modified by nodules\/crystals.       \u003Cbr \/\u003E(J) The whole water escape discussion is a red herring (unrelated to the topic).\u003Cbr \/\u003E   Hope this helps the discussion!\u003Cbr \/\u003EPaul Combs\u003Cbr \/\u003Ecombsbp@yahoo.com"},"link":[{"rel":"edit","type":"application/atom+xml","href":"http:\/\/www.blogger.com\/feeds\/5517176012861550589\/7939391156095008352\/comments\/default\/7870720889253293223"},{"rel":"self","type":"application/atom+xml","href":"http:\/\/www.blogger.com\/feeds\/5517176012861550589\/7939391156095008352\/comments\/default\/7870720889253293223"},{"rel":"alternate","type":"text/html","href":"http:\/\/ediacaran.blogspot.com\/2010\/07\/21-ga-multicellular-colonial-organisms.html?showComment=1330806085122#c7870720889253293223","title":""}],"author":[{"name":{"$t":"Anonymous"},"email":{"$t":"noreply@blogger.com"},"gd$image":{"rel":"http://schemas.google.com/g/2005#thumbnail","width":"16","height":"16","src":"https:\/\/img1.blogblog.com\/img\/blank.gif"}}],"thr$in-reply-to":{"xmlns$thr":"http://purl.org/syndication/thread/1.0","href":"http:\/\/ediacaran.blogspot.com\/2010\/07\/21-ga-multicellular-colonial-organisms.html","ref":"tag:blogger.com,1999:blog-5517176012861550589.post-7939391156095008352","source":"http://www.blogger.com/feeds/5517176012861550589/posts/default/7939391156095008352","type":"text/html"},"gd$extendedProperty":[{"name":"blogger.itemClass","value":"pid-1577025230"},{"name":"blogger.displayTime","value":"March 4, 2012 at 7:21 AM"}]},{"id":{"$t":"tag:blogger.com,1999:blog-5517176012861550589.post-8132168200894897869"},"published":{"$t":"2012-02-13T21:13:15.924+11:00"},"updated":{"$t":"2012-02-13T21:13:15.924+11:00"},"title":{"type":"text","$t":"Why do you undermine your stated respect for docum..."},"content":{"type":"html","$t":"Why do you undermine your stated respect for documentaries by calling them \u0026quot;docos\u0026quot; like a bullet-headed jackdaw?\u003Cbr \/\u003E\u003Cbr \/\u003EKen Burns is a much lower life form on the documentary evolutionary tree than Bronowski and Attenborough and does not qualify to be mentioned in the same breath as those superlative practitioners of the art."},"link":[{"rel":"edit","type":"application/atom+xml","href":"http:\/\/www.blogger.com\/feeds\/5517176012861550589\/5773360734106668159\/comments\/default\/8132168200894897869"},{"rel":"self","type":"application/atom+xml","href":"http:\/\/www.blogger.com\/feeds\/5517176012861550589\/5773360734106668159\/comments\/default\/8132168200894897869"},{"rel":"alternate","type":"text/html","href":"http:\/\/ediacaran.blogspot.com\/2008\/12\/bestest-documentaries-ever.html?showComment=1329127995924#c8132168200894897869","title":""}],"author":[{"name":{"$t":"Anonymous"},"email":{"$t":"noreply@blogger.com"},"gd$image":{"rel":"http://schemas.google.com/g/2005#thumbnail","width":"16","height":"16","src":"https:\/\/img1.blogblog.com\/img\/blank.gif"}}],"thr$in-reply-to":{"xmlns$thr":"http://purl.org/syndication/thread/1.0","href":"http:\/\/ediacaran.blogspot.com\/2008\/12\/bestest-documentaries-ever.html","ref":"tag:blogger.com,1999:blog-5517176012861550589.post-5773360734106668159","source":"http://www.blogger.com/feeds/5517176012861550589/posts/default/5773360734106668159","type":"text/html"},"gd$extendedProperty":[{"name":"blogger.itemClass","value":"pid-1577025230"},{"name":"blogger.displayTime","value":"February 13, 2012 at 9:13 PM"}]},{"id":{"$t":"tag:blogger.com,1999:blog-5517176012861550589.post-7181049600181436195"},"published":{"$t":"2012-02-09T23:06:26.864+11:00"},"updated":{"$t":"2012-02-09T23:06:26.864+11:00"},"title":{"type":"text","$t":"Hmmm...
