Ludwigia Posted June 4, 2013 Share Posted June 4, 2013 For instance the ones from the Toarcian and lower Aalenian succession in the Queen Charlotte islands. I'd post a pdf here, but the file is too big. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Missourian Posted June 5, 2013 Author Share Posted June 5, 2013 In several posts in this thread, I described and illustrated Osagia, which is diagnostic of the Farley Limestone: So what exactly is Osagia? These are tiny nodules, a.k.a. oncolites, that are made up of filamentous algae and encrusting forams. They formed around tiny shell fragments or other nuclei, and then grew as they rolled around in a high-energy environment. A closer look reveals the snake-like foram Tolypammina mixed in with several oncolites: There is also an ostracod in the field of view. Can you find it? A little closer to a couple oncolites: The forams stand out nicely, but the algal filaments are too small to see at this magnification, assuming their stucture is preserved at all.

Missourian Posted June 13, 2013 Author Share Posted June 13, 2013 New outcrops turn up even when I'm not looking. When checking out a spur of the bike path, I stumbled across some Argentine Limestone: The Argentine can be very good in spots, but it's normally pretty stingy fossil-wise. It's always worth taking a closer look: As usual, all I could find were run-of-the-mill invertebrates. Here are some poorly preserved brachiopods, crinoids and bryozoans: Better luck next time....

lissa318 Posted June 13, 2013 Share Posted June 13, 2013 LOL! I enjoy following your posts! Fabulous pictures as always. I am halfway tempted to send you my cods and probable clam shrimp just so someone can actually see them and get some good pics!!!!!! Looking forward to seeing what you add next.

Since I'm finding nothing but busted brachs and stems around here lately, I have to keep myself entertained somehow. Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted June 17, 2013 Author Share Posted June 17, 2013 In a post near the beginning of this thread ( http://www.thefossilforum.com/index.php?/topic/25424-backyard-trip/?p=281796 ), I mentioned finding a 'nest' of crinoid calices and partial crowns in the Liberty Memorial Shale several years ago. I included a photo, but it wasn't a very good one. It's time for a second look: There are about 130 calices overall: The microscope doesn't reveal much more detail, but here goes anyway: When I found the patch, there were several calices sitting on the surface of the shale. A little digging revealed many more. I didn't see any in the fresh shale below, so I scooped up a bunch of the loose stuff to wash and sort at home. I returned to the exposure a couple months ago ( http://www.thefossilforum.com/index.php?/topic/25424-backyard-trip/?p=401426 ), but I didn't find any more. Context is critical.

Those bryozoans are probably common but they can be hard to spot. I was lucky to find them in a clump. Context is critical. Link to comment Share on other sites More sharing options...
