Missourian Posted January 29, 2013 Author Share Posted January 29, 2013 Did someone mention brachiopods? Juvenile Derbyia sp. attached to Neospirifer sp. Middle Creek Limestone, Pennsylvanian Jackson County, Missouri Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted January 29, 2013 Author Share Posted January 29, 2013 Pelecypods? Winterset Limestone, Pennsylvanian Jackson County, Missouri I've had a bit of an adventure trying to identify these things. At first, I thought they could be graptolites. I then considered bryozoans, brachiopods (Linoproductus or Isogramma) as possibilities, before I settled on some kind of pelecypod displaying microstructure. I'm still not sure.... Anyway, here's how they appear with slight magnification: Another specimen displays an exposed surface that is similar in appearance to a ruffled potato chip. I'm not sure where it is at the moment.

Missourian Posted January 30, 2013 Author Share Posted January 30, 2013 Silicified sponge Heliospongia excavata Spring Hill Limestone, Pennsylvanian Johnson County, Kansas Years ago, I used Sno Bol toilet bowl cleaner to extract this sponge from a piece of limestone: It is only a fragment, but it displays some of the best detail I've seen. Many pores cover the surface. These are ostia, which are where water was drawn into the organism. A little closer: Water exited the sponge through the much larger osculum: As we peer down into the osculum, more pores can be seen in the interior canal (spongocoel): Context is critical.

Missourian Posted February 1, 2013 Author Share Posted February 1, 2013 Sponge detail Heliospongia ramosa Quindaro Shale, Pennsylvanian Miami County, Kansas This sponge may have been dead and slightly decomposed when it was buried.

Bullsnake Posted February 3, 2013 Share Posted February 3, 2013 To me, it resembles popcorn. I see oatmeal I was going to try to add some conulariid detail, but can't seem to get the quallity pictures. Do you have any handy? Steve Link to comment Share on other sites More sharing options...

Foram-Mike Posted February 6, 2013 Share Posted February 6, 2013 (edited) Hi missourian nice topic ! A field trip into unknown sediments under the microscope is quite an adventure. Since 6 years I am enjoying this kind of fossil hunting and recently stumbled into Miocene Hungarian stuff. I think it is Planularia costata. - looks like a fragile leaf. To note: this is just one object of hundreds more seen in 2-3h of investigation.

astron Posted February 7, 2013 Share Posted February 7, 2013 Very interesting and nice job Missourian and everyone!!! Here is a Dicotyllophyllum leaf I have found recently in my hunting area with a tiny thing on it. These are the best 2 of about 100 pics I have tried with it! Microscopical insect or winged seed??? Apparently the microscopy might clear it out... Astrinos P. Damianakis Link to comment Share on other sites More sharing options...

AgrilusHunter Posted February 9, 2013 Share Posted February 9, 2013 Hi Astrinos, I don't think it is an insect. I would lean towards seed but that is just a guess. Hope this helps!

Missourian Posted February 14, 2013 Author Share Posted February 14, 2013 We just got back from a trip to Florida. I didn't find too many fossils, but I did have a chance to pick some old shells from some artificial fill along the causeway to Sanibel: I figure that this is some Pleistocene stuff dug up from somewhere in the Fort Myers area. Many of the shells were filled with lightly cemented sand. The variety of shells is interesting. Some types, such as the fighting conch and olive, can be found on the nearby beaches. Other forms no longer seem to be present in this part of Florida. These include corals. I found two pieces: Up close: Context is critical. Link to comment Share on other sites More sharing options...
astron Posted February 14, 2013 Share Posted February 14, 2013 Perfect, Missourian!!! It seems you have found the paradise of the shells And corals don't get back... Those details are stunning It looks like they have some Cretan brothers Astrinos P. Damianakis Link to comment Share on other sites More sharing options...
