Plantguy Posted October 23, 2009 Share Posted October 23, 2009 Bruno, contined amazement and awe here! Spectacular specimens. I was going to say print the book now...but I'm not sure I could come close to affording it with all of your recent pictures and the volumes of the old ones. Maybe a hardcopy is now out of the question and only an ebook via download is appropriate... ..... Thanks for the continued marvelous postings.

Plantguy Posted October 29, 2009 Share Posted October 29, 2009 (edited) Hi Bruno, loved the elegans photos... It's striking to see how many different species existing and now extinct have incorporated that hexagonal pattern into their structure. I havent found a Sigillaria yet, maybe some day, but I have found some of the various corals using the pattern, but my favorite that I found was a very small Cretaceous trace fossil called Paleodictyon. I think the specimen I found is still at the Geology Dept of my old school in California and I unfortunately dont have a photo. But here's a link of what they looked like...imagine an animal/worm beneath sediment somehow creating hexagonal burrows...pretty wild stuff?? At least the plant was out in daylight and could see what it was doing... http://www.agiweb.org/geotimes/dec02/technology.html Regards, Chris Edited October 29, 2009 by Plantguy Link to comment Share on other sites More sharing options...
