Missourian Posted December 24, 2012 Author Share Posted December 24, 2012 Arenaceous forams Tolypammina sp. Fontana Shale, Pennsylvanian Jackson County, Missouri These are attached to a 17 mm pelecypod shell fragment. Without magnification, these appear as white fuzz or salt encrustation. A closer view: Other forams, such as Ammovertella, are likely present as well, but they would be difficult to pick out among the Tolypammina. These forams, along with the alga Girvanella, formed these thick encrustations known as Ottonosia. Context is critical. Link to comment Share on other sites More sharing options...

Missourian Posted December 27, 2012 Author Share Posted December 27, 2012 Fusulinids have long been studied by micropaleontologists. Their great numbers, minute size, and variation (to experts, at least) make them ideal for biostratigraphy. I just find them fascinating under the scope. Triticites sp. Beil Limestone, Pennsylvanian Osage County, Kansas The largest fusulinid is 5 mm long. Triticites sp. Ervine Creek Limestone, Pennsylvanian Holt County, Missouri The largest fusulinid is 6 mm long.

Missourian Posted December 29, 2012 Author Share Posted December 29, 2012 Like fusulinids, conodonts are used extensively in biostratigraphy. These tiny tooth-like fossils can be found in many rock types, but they are most easily spotted in black shales. The conodonts shown here were found in the Pennsylvanian Stark and Hushpuckney Shales of Jackson County, Missouri.Streptognathodus sp. (~1 mm) Streptognathodus sp. pair (~2 mm) Unfortunately, these are only negatives in the shale.Ligonodina sp. (~3 mm) Ozarkodina sp. (~1 mm negative) Hibbardella sp. (edit: this could be Idioprionodus sp.) (~1 mm) Hindeodella sp. (~1 mm) These conodonts proved difficult to image with the iPhone. The light amber fossils were overexposed as the camera tried to balance out the lighting of the black shale. The play of light in the nearly transparent calcium phosphate of the conodonts can make it difficult to discern their form and structure. The Ligonodina is the only one that came out satisfactorily.
