Hoheneck (Triassic of Germany)

Where: Baden-Württemberg, Germany (48.9° N, 9.2° E: paleocoordinates 15.9° N, 17.2° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Upper Lettenkeuper Member (Erfurt Formation), Longobardian (242.0 - 235.0 Ma)

• Hohenecker Kalk of the Upper Lettenkeuper; now formally the Erfurt Formation of the Lower Keuper (see Deutsche Stratigraphische Kommission 2005: Cour. Forsch.-Inst. Senckenberg 253:1-296). This locality is Longobardian (late Ladinian) in age.

• bed-level stratigraphic resolution

Environment/lithology: estuary or bay; limestone

• "this formation has been interpreted as representing an estuarine environment, supported by the frequent succession of very shallow marine, limnic/brackish swamp, and deltaic deposits" (Schoch 2006: JVP 26, 29)

Size class: macrofossils
