Ron E. Posted July 18, 2009 Share Posted July 18, 2009 The Little Sugar Creek has a spot where these rocks are commonplace. I thought the first one was fossilized mud. Then, once I started learning more about fossils, I discovered stromatolites. I believe that is what i have here. The first one is a bit blurry, I had to shoot it through aquarium glass without flash to avoid washing it out. You see, these rocks look fantastic in a freshwater tank! I have a java fern rooted on the first one, I don't want to disturb it. Here's a second one, in my angelfish breeder tank And here's a third. I only have two tanks ;-) What do ya'll think? Are these stromatolites? Thanks, Baldy Link to comment Share on other sites More sharing options...
jeepinthemud Posted July 18, 2009 Share Posted July 18, 2009 If i had to say, I would say the first might be, but I am not so sure of the latter two.. All the stromatalites i have seen have just been little mounds from the side, rather than the entire structure, so i could easily be wrong..

The thing is that these were all collected within 100' of each other. The rock structure really does look identical, that first one has been in the tank for a couple of years and has lots of algae growth on it.

jeepinthemud Posted July 18, 2009 Share Posted July 18, 2009 Haha.. like I said, Ive only seen one view of one type of stromatalite, so I am not one to actually ID them.... but they are very nice...

No worries, mate :-) But your comment did cause me to remember some more detail, and thanks. BTW, I know where more of these puppies are Also, I have another real mystery fossil/pseudofossil, but I'm not going to overwhelm the board. I'll wait until this thread dies out.

mommabetts Posted July 18, 2009 Share Posted July 18, 2009 Do you know the age of the formation where it was collected at? Link to comment Share on other sites More sharing options...
Ron E. Posted July 18, 2009 Author Share Posted July 18, 2009 Do you know the age of the formation where it was collected at? As far as I know, still in the Boone Limestone, early Mississippian. It's close to where highway 71 first enters SW Missouri. Link to comment Share on other sites More sharing options...
ashcraft Posted July 18, 2009 Share Posted July 18, 2009 I think they are all stromatolites, but in your view, you are showing either looking down on them or up at the bottom. The diagnostic feature of a stromatolite is the laminae, visible in cross section. Attached are a few of my stromatolites I have picked up along the way, all are out of the St. Peter sandstone, which is Ordovician.

Auspex Posted July 19, 2009 Share Posted July 19, 2009 Pics wouldn't upload, trying again.....Hmmmm, anybody else having problems uplaoding pics?????? TEST Nope, I guess not...

ashcraft Posted July 19, 2009 Share Posted July 19, 2009 Try again....I had resized them to 500kb or so, have gone further down. Picked up a computer virsu last week, got it all cleaned up, but things still aren't working quite correctly..... Seems to be working know with the much smaller photos, maybe bad karma yesterday. Well maybe Karma is still a littl sick, pics double posted as you can see...... ashcraft, brent allen Link to comment Share on other sites More sharing options...

Terry Dactyll Posted July 19, 2009 Share Posted July 19, 2009 Very nice examples.... They cut & polish them in the uk....Heres a couple I have collected, although not like radiused spherical balls like yours, mine must just of been chunks or parts of a layer, found in a lower Jurassic quarry.... They are chunks of 'Cotham marble' or 'Landscape marble'... when cut & polished this material resembles a landscape.... or so thought to resemble one by the Victorians...I think they make pendants out of it aswell.... I'll get them cut one day....lol heres a link to some for sale polished http://www.fossilsdirect.co.uk/details.cfm?prodref=SP712 Cheers Steve... And Welcome if your a New Member...

And don't forget, stromatolite-ophiles, that I have access to more, if interested. It's amazing how good these things look in freshwater tanks, surrounded with plants and driftwood.

Auspex Posted July 19, 2009 Share Posted July 19, 2009 Dave Freeman (a friend of mine and MIA member of the Forum) threw this in with some bird stuff I bought from him: (...this is your brain in algae) It has been cut, but not polished.

ashcraft Posted July 20, 2009 Share Posted July 20, 2009 I have talked to Dave a number of times about my stromatolites. Mine are nice when cut and polished, but his are gorgeous. Here is a couple of pics of him cutting some of his stromatolites: http://www.lakeneosho.org/Paleolist/26/index.html Brent Ashcraft ashcraft, brent allen Link to comment Share on other sites More sharing options...
