Plate XXIII. Special Pennsylvanian Organisms

(A) A fusulinid packstone-wackestone with interstitial matrix of silt to fine sand
size bioclastic debris-striking bimodal sorting; facies P5 of Chapter VII and
standard microfacies 10. Note the orientation of the spindle-shaped fusulinids is
such that most are transverse sections (the lower right corner displays a perfect
axial-longitudinal section). Most of the fusulinids are worn and thoroughly micri-
tized showing transport for some time or distance before deposition. Seven litho-
clasts and a transverse section of a crinoid stem are seen. Leavenworth Limestone
(No.2 limestone) from Oread megacyclothem of Kansas, -Locality 3 of D.F.
Toomey (1969a) who also kindly furnished the photograph. Thin section, x 7

(B) Komia packstone, thick-bedded detrital Mid Pennsylvanian limestone.
Finer particles have in-filtered the coarse grain-supported fabric of Komia with
lithoclasts. Komia is most probably a small dendroid, branching stromatoporoid
and is found in detrital accumulations representing shoal environments in Middle
Pennsylvanian strata of the southwestern United States (see Fig. VI-24). The sam-
ple EDCW-26, from the Bug Scuffle Limestone, is from a Desmoinesian carbon-
ate bank in the Sacramento Mountains of New Mexico. Thin section, x 15
