Cracks can be seen in the smaller example. <br /><br />The authors of the original paper have to explain why such a fabric that is essential for the specimens to be a multicellular colonial organism, differs from specimen to specimen, is supposed to be the method of growth at the margins yet does not reach the margins in some, cuts right through a latter pyrite nodule, and is missing altogether in some.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5517176012861550589.post-16574413166566231322010-08-08T02:41:10.302+10:002010-08-08T02:41:10.302+10:00I don't see anything at all like the radial st...I don't see anything at all like the radial structure exhibited in the fossils in your bubbled mat examples.BJNnoreply@blogger.com
