3-D Fossils Found in Canada 36

Posted by michael on Friday July 16, 2004 @07:14PM from the rocky-road dept.

smooth wombat writes "The BBC has a story with pictures of fossils found in Canada which are three dimensional. Even more interesting is that scientists consider the creatures, called rangemorphs, to be neither animal nor vegetable. In a related matter, geologists added the Ediacaran Period, in which these fossils lived, to their official history of Earth, the first new period to be added in 120 years."

    Read a story introduced by the title "3-D Fossils Found in Canada"? I'm as likely to read that as a story titled "New Pentium PC does arithmetic".

  If I had to take a swag, I'd say that the significance is that they're fossils of soft-bodied critters [um, or "thingies"] that were found in 3D, as most are squashed flat by the process that fossilized them.

    Also important is the fine detail preserved in the fossils, down to 30 micrometers. [aaas.org]

    This is directly related to my thesis work, so I'll pretend to know what I'm talking about.
    
    The main significance is that they're stunningly well-preserved examples of a fauna which predates the Cambrian Explosion - this might increase the chances that sensible attributions to extant animal phyla can ultimately be made.
    
    One hears a lot of nonsense about the Ediacarans, but there's a substantial body of opinion that they're nothing more than Cnidarians - and possibly Cnidarian-like Ctenophore ancesto

  ...really is about rather than the pop-science version. After all, fossils have been 3D since the dawn of time - well, almost anyway.
  I've personally never encountered anything that had fewer than three spatial dimensions. But I'm sure what was meant was that the fossil was informative in all three dimensions.

      No? How about your shadow there on the floor? How many dimensions does it have?
      
      Shadow are still in 3d don't forget it start's at your body and ends on the floor. And even if your only going to talk about that part of the shadow that hit's the floor it's still 3d as the floor is not flat. Nor is it of 0 depth.

No wonder all those dinosaurs died out, if they were 2-dimensional. I mean, how would they eat 3D plants?

  This is blasphamy, and the fossil record is no proof of evolution. All a fossil proves is that somthing existed at one time, but no longer does.

  yes, but there are side effects to wearing the special glasses. Besides headaches, everything will look monochrome, and billboards will only have "OBEY" and "MARRY AND REPRODUCE" written on them. Your money will read "THIS IS YOUR GOD" Some people will look like hideous space aliens, and will speak into their watches about you, "he can SEE!".

The finds show that the organisms were assembled in fractal patterns from frond-like building blocks. They were unable to move and had no reproductive organs, perhaps reproducing by dropping off new fronds .
Does Chris Langton know about this? It appears that his cellular automata self-reproduction structures may have been right on the money!
