Red mudstone bed near Tenduar village (Triassic of India)

Also known as Tenduadh

Where: Madhya Pradesh, India (24.0° N, 81.4° E: paleocoordinates 42.6° S, 51.2° E)

• coordinate stated in text

When: Upper Tiki Member (Tiki Formation), Carnian (237.0 - 228.0 Ma)

• "Red mudstone beds above and below the Unio bed exposed near Jora village." The paper references two separate layers in this same locality, above and below an Unio bivalve bed. Since the two layers are indistinguishable in age and formation, both are included here.

•

•This paper says Carnian-Norian but cites older references than Mukherjee and Ray (2012, also linked to this collection) which states Tiki Fm is Carnian.

Environment/lithology: fluvial; concretionary, red, calcareous mudstone and concretionary, red, calcareous claystone

• Red mudstone bed above/below the Unio bed exposed near Jora village. "The Lower Tiki Formation, about 28-30m thick, is characterized by presence of predominantly reddish mudstone/claystone with thin calcareous intercalations, laminated siltstone, calcarenite, limestone and feldspathic quartzarenite. The non-laminated mudstone beds usually contain calcareous globules, calcified rootlets, calcareous nodules, and small to large concretions. The Upper Tiki Formation overlying the conglomerate bed containing lime-pellet comprises mainly of sandstone and reddish mudstone which are deposited as an alternate sequence. Fossils are mainly recorded from the lower Tiki Formation. The unionid bivalve consisting beds act as marker for the fossiliferous horizons of Lower Tiki Formation."

Size classes: macrofossils, mesofossils
