Treatment

Plagiosauridae indet.

Reference material

TF 1453 ( Fig. 2e–f View Figure 2 ), a dermal bone ( Suteethorn et al., 1988).

Formation/age

Huai Hin Lat Formation (Carnian–Norian).

Locality and sediment

Outcrop near the Chulabhorn Dam, Kon San District , Chaiyaphum Province. The outcrop is located in the upper part of the Huai Hin Lat Formation ( Suteethorn et al., 1988). The specimen was embedded in a block of carbonaceous black shale rock .

Description

The specimen TF 1453, approximately 22 mm wide and 25 mm long, shows a peculiar ornamentation consisting of tubercles or pustules on its ventral surface. Dorsally, the surface shows some faint radiating grooves and ridges. Based on its ornamentation, TF 1453 was interpreted as a dermal bone fragment of a temnospondyl and was assigned to Plagiosauridae . A comparable ornamentation is observed in Middle to Late Triassic Plagiosauridae , e.g., Gerrothorax pulcherrimus and Plagioscutum ochevi from Europe ( Shishkin, 1986; Warren and Snell, 1991; Suteethorn et al., 1988; Jenkins et al., 2008).
