Where: Himachal Pradesh, India (32.0° N, 78.0° E: paleocoordinates 43.5° S, 60.8° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Mikin Formation, Olenekian (251.2 - 247.2 Ma)

• Part of Flemingites beds

Environment/lithology: offshore; shelly/skeletal, gray wackestone

• The Himalayan Lower Triassic thus formed part of a large deeper-neritic basin and the Spiti sediments were deposited on wide stable shelf to provide extensive continuity to the beds
• gray well oxygenated and bioturbated bioclastic wackestones rich in fragments or complete specimens of large ammonoids (beds 13-16)
