Bullsnake Posted March 7, 2012 Share Posted March 7, 2012 You guys let me know if you plan something "back east". I'd love to tag along. Ramo You know it, Ramo! Steve Link to comment Share on other sites More sharing options...
Missourian Posted March 7, 2012 Share Posted March 7, 2012 (edited) Here are some specimens from last Sunday's haul. From the quarry pit.... Brachiopods, including Derbyia and Composita. Lower Winterset Limestone: Many of the Derbyia I'd collected broke apart. I guess I'll have to go back and get some more. Oncolites, an algal-foraminiferal covering on various shells. Fontana Shale: Very tiny, white forams within the algae can be seen under magnification. The covered shells include pectens, myalinids, Derbyia and unidentified types. Crinoid stems found at the same spot had no algal covering. Unidentified gastropod in hash. Limestone within the lower Wea Shale: I really like finding unfamiliar gastropods. There are quite a few types found in the Pennsylvanian, and I'm nowhere close to having them all. This one could be Soleniscus, but there are a few other possibilities. And a few from the Winterset at the highway ramp.... Most of the good stuff here can be found in the cross-bedded oolite. Individual 0.5 mm ooids can be seen here: In places, there are pockets that follow the cross beds that contain shell debris and well-preserved larger mollusks, brachiopods, bryozoans and trilobite fragments. This chunk shows both oolite and bioclastic rock, with some chert mixed in: The nautiloid Liroceras is peeking out of the other side of this rock: Silvery Composita brachiopods are plentiful here: These came from this rock, which was also shown in my thread above: The fossils in the oolite tend to be 'color coded'. Mollusks often have reddish orange shells, brachiopods are a silvery gray, trilobites are chalky white, bryozoans are gray, and wood fragments are black. Speaking of orange mollusks.... Bullsnake, do you still have that skinny Paleostylus gastropod? It deserves a place in this thread. The bluish limestone beds below the oolite have a somewhat similar fauna, including this large Wilkingia clam: The slabby beds above the oolite is a tidal flat deposit and has no fossils besides a few scattered Cordaites leaves. We didn't find any today. Here's one found at a nearby cut several years ago: This piece of limestone, which contains a desiccation crack and many burrow traces, may be associated with the tidal flat beds: Edited March 7, 2012 by Missourian Context is critical.

Bullsnake Posted March 7, 2012 Share Posted March 7, 2012 This thread has been brought to you by the letter 'C'. Wondered what you'd come up with for that! A few things I found at the 2nd stop: A very incomplete, very worn, broken during removal, but pretty good sized straight shelled ceph. A very incomplete, very worn, broken by nature, but pretty cool nonetheless clam. A nice hash plate with pecten, and myalina. A genal spine(no big deal, but my first). These two brachs were almost catch and release, until I turned it over and saw the ortocone on the back! Steve Link to comment Share on other sites More sharing options...
Missourian Posted March 7, 2012 Share Posted March 7, 2012 Wondered what you'd come up with for that! I had to go with old-school Sesame Street. A nice hash plate with pecten, and myalina. I like how they're arranged on the surface. A genal spine(no big deal, but my first). The hills have eyes.... There are more of 'em in there. Context is critical.

grokfish Posted March 7, 2012 Share Posted March 7, 2012 Finally got around to scanning some of my finds. First up is the crustacean found in the stark shale...it is a terrible photo, I hope to take a better one tonight... Second up is the trilobite tail found in the winterset...needs some prep. Thirdly some odds and ends- shark teeth, gastropods, ammonite (I think), and something mysterious... Opposite side of some of the finds... Link to comment Share on other sites More sharing options...
Bullsnake Posted March 7, 2012 Share Posted March 7, 2012 I didn't know you found any teeth until Kehbe told me after you left. That's awesome! Steve Link to comment Share on other sites More sharing options...
grokfish Posted March 7, 2012 Share Posted March 7, 2012 I didn't know you found any teeth until Kehbe told me after you left. That's awesome! Yeah! First shark tooth finds from the pennsylvanian! Sorry I had to bolt, and didn't get a chance to share finds...one of those moments where I really got into hunting, lost track of time, and realized I was late Link to comment Share on other sites More sharing options...
