ammonites
Thecia podolica Community, Ternava suite, Podolia (Silurian of Ukraine)

Where: Ukraine (48.7° N, 26.8° E: paleocoordinates 21.9° S, 7.4° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Ternava Suite Formation, Wenlock (428.2 - 422.9 Ma)

• Kitaigorodian superhorizon. Ternava Suite in the Yaruga series.

• formation-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal grainstone

• "Abundance of fine detrital fractions and nodular texture indicate moderate wave activity. There are spotty settlements, with moderate population densities. The polyparies and corallites are of intermediate size in this zone. The presence of blue-green algae indicates shallow water. The fine clastic material tends to be deposited further offshore. The absence of bioherms indicates a water depth in excess of 20-30 meters. Assigned to BA 3 because of the relatively high percentage of disarticulated shells indicating a moderate level of turbulence. Location in the sequence for this comm. is not far from the Pentamerus gothlandicus comm. and the Bumastus xestos comm."
• "detrital limestones containing abundant shelly and crinoidal debris (up to 60%)...abundance of fine detrital fractions..."
