Bugarikta (PIN collection 2010) (Triassic of Russian Federation)

Where: Krasnoyarsk, Russian Federation (65.0° N, 100.0° E: paleocoordinates 57.8° N, 42.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Bugarikta Formation, Griesbachian (252.2 - 251.3 Ma)

Environment/lithology: terrestrial; lithified mudstone

• Tunguska basin
• "At the base of the slope, which is covered with trapp debris, is exposed a strata of green sandstones, interbedded with layers of red and brownish sheet-like sandstones. One of these brownish layers is filled with remains of Esterians, Ostracods, imprints of vegetation and fish remains."

•"a small thin plate of fine-lamellate brown sandstone. This fine-granulate sandstone with dispersed particles of clay should rather be referred to siltstones. On the elastical material of sandstone there are observed unputrified particles of the eruptive basal rock. The texture of this rock presents an alternation of very thin (0.5 mm) layers of dark and light colours, of sandstone and clay origin respectively." (Shiskin 1998)

Size class: macrofossils

Preservation: mold/impression
