Diagenetic calcite occurred as micrite disseminated in the clay matrix, often associated with pyrite, and as microsparite that filled residual porosity in bioclasts (Figure 4(b)) and septarian
veining in phosphate nodules.

Moreover, some layers are rich in intrabasinal carbonate-rock fragments including septarian
nodules, derived from the calcretes of the Agreda Fm.
Eight specimens, including granite, rhyolite, blueschist, septarian
concretions, and a triolibite, were loaned to WMI from the geology collections at the University of Southern Indiana.
Less well-known are undocumented fossils, sedimentary structures, and "curiosities." As a service (earning project, the 2011 UTM Paleobotany class conducted a "forensic reconstruction" of the collection yielding 218 specimens (172 fossil plants [168 Carboniferous; 4 Paleogene-Neogene], 29 invertebrates and ichnofossils, and 17 sedimentary-diagenetic features [Ferricrete, leisegang, septarian
