Ron E. Posted August 1, 2009 Share Posted August 1, 2009 Some pics from my trip to Springfield, MO, as recommended by crinus, that took place on 7/24/2009. Cool brachiopod preservation,. you don't usually see the thinness of their shells. Found these guys on a rock in a creekbed twenty miles south of town, near a quarry and a state park. It was almost wedged up under a poured slab that made crossing the creek easier on dumptrucks. Anomalous? I didn't find a single rock like this one anywhere in the area. Oh, and a species ID would be appreciated Here's the reverse. The huge quartz crystals looked very much out of place with the existing rocks. TONS of platyceras in the Burlington rocks! Also, not unusual to find specimens that were badly worn at time of fossilization, then were fossilized full of sandy stuff from the bottom. Kewl! Found this in some crinoid-encrusted limestone. A crushed calyx? It's about 2" in diameter. Whew! Only have 43.77k left! Most images I've ever uploaded for a post! Link to comment Share on other sites More sharing options...
Auspex Posted August 1, 2009 Share Posted August 1, 2009 Your "dump truck erratic" probably didn't come from too far away, given the cost of hauling rock fill; maybe from a quarry level that is otherwise not exposed in the area? Good trip!

Mike Owens Posted August 1, 2009 Share Posted August 1, 2009 I have seen this type of formation in Texas. Can't remember where. Nice finds. -----"Your Texas Connection!"------ Fossils: Windows to the past Link to comment Share on other sites More sharing options...
barefootgirl Posted August 1, 2009 Share Posted August 1, 2009 Very sweet finds! In formal logic, a contradiction is the signal of defeat: but in the evolution of real knowledge, it marks the first step in progress toward victory.

Shamalama Posted August 1, 2009 Share Posted August 1, 2009 Nice finds! You unusual rock looks like it has snail casts in it. the texture of the rock and presence of Quartz crystals imply to me that it's a chert more than a limestone. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
