Blumenthal 1 locality (Triassic of Russian Federation)

Also known as Blyumental-1, locality 27 (Tverdokhlebov et al, 2003); Burtya River basin, Saratov Univ 104/13, 19

Where: Orenburg, Russian Federation (51.3° N, 55.7° E: paleocoordinates 31.6° N, 46.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Kopanaskya Formation, Induan (252.2 - 251.2 Ma)

• Mainly confined to the middle part of the Vetluzhian series (Ochev, 1978).

•"Kopanskaya Svita. Lower Triassic." (Tverdokhlebov et al., 2003). These authors assign the Kopanskaya Svita to the Induan stage (ibid. fig. 2).

•Originally entered group name >>Vetluzhian<< is removed for it is no lithostratigraphic term (TL).

• group of beds-level stratigraphic resolution

Environment/lithology: "channel"; medium-grained, pebbly, brown, yellow sandstone

• "Channel deposits." (Tverdokhlebov et al., 2003).

•Originally enterd paleoenvironment >>karst indet.<< was modified accordingly (TL).

• "Buff-brown, medium-grained, cross-bedded sandstone with pebbles of clays." (Tverdokhlebov et al., 2003).

Size class: macrofossils

Reposited in the PIN

• Collections of Saratov University, now (entirely?) transferred to the PIN.

Taxonomic list

• The primary reference is currently not at hand to the modifier of the present collection. Thus, it is hard to judge if the Chasmatosuchus sp. specimens reported by Ochev (1978; SGU 1043/13 and 19, probably should read SGU 104B/13 and 19) are identical to those reported by Sennikov (2008; PIN 4167/3 and 4) from the Blyumental-1 locality. Tverdokhlebov et al. (2008) list only one single vertebral fragment from Blyumental.
