Loc. 4.1, Listice Sect., Beroun, Listice sect. 760, Motol (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 12.9° E)

• Paleocoordinates: 32.9° S, 4.2° E (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Motol Formation, Homerian (430.5 - 427.4 Ma)

• "The age of the limestone complex could span the top of the C. lundgreni Biozone and the succeeding zones from M. dubius parvus to M. vulgaris."

• group of beds-level stratigraphic resolution

Environment/lithology: marine; graded, volcaniclastic, shelly/skeletal, gray, cherty/siliceous limestone and volcaniclastic, gray shale

• "...volcaniclastics pass transitionally into a sequence of crinoidal limestones with tuffite interbeds. The most fossiliferous horizons are the lower limestone beds 24 and 25...Higher in the section there are then massive lenticular grey tuffitic and bioclastic crinoidal limestones with levels of brown tuffites containing small limestone lenses. The massive limestones show cross-bedding at some levels, and silicification. Levels with tuffites also show graded bedding...The tuffitic Lsts and shales contain common spores of early land plants..."
