Tugrikin Shire I [HMNS-GIN] (Cretaceous of Mongolia)

Also known as Tögrögiin Shiree, Tugrig Shire, Toogreeg Shire

Where: Omnogov, Mongolia (44.2° N, 103.3° E: paleocoordinates 41.8° N, 92.3° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Tugrugyin Member (Djadokhta Formation), Late/Upper Campanian (83.5 - 70.6 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: dune; poorly lithified, burrowed, fine-grained, red, white sandstone

• eolian dune, erg
• "yellowish-white sandstones"; "Tugrik sandstones are compositionally and texturally sub-mature. They are generally poorly consolidated, moderately well-sorted, fine-grained, sub-rounded to well-rounded, and present a 'frosted' appearance. Colors vary from pink (induced by minor amounts of hematite), to white, reflecting the absence of any hematitie or other coloring agent."

Size classes: macrofossils, mesofossils

• both insect and mammal damage to bones
