นักวิจัยพบฟอสซิล “สัตว์ขาปล้องน้ำจืด” – Silurian Maldybulakia saierensis sp. nov. from the Saier Mountains, western Junggar, Xinjiang. A, five types of partially articulated sclerites (holotype, BGEG-SE-06a). B, complete T-tergite (paratype, BGEG-SE-04). C, ring tergite (paratype, BGEG-SE-05). D, internal mould of a B-pleurotergite, showing medium-sized tubercles on the median lobe of the posterior part (paratype, BGEGSE-28-1). E, caudal pleurotergite (paratype, BGEG-SE-23). F, B-pleurotergite with forward-bending paratergal spines (paratype, BGEGSE-02-1). G, a complete T-tergite (upper) and B-pleurotergite with backward-bending paratergal spines (lower), with a magnified view of the ornament (inset) (paratype, BGEG-SE-21a-1, 2), H, articulated caudal pleurotergite and telson sclerite (holotype, BGEG-SE06b). I, telson sclerite (paratype, BGEG-SE-21b-3). J, three-dimensionally preserved B-pleurotergite (paratype, BGEG-SE-16a-1). Abbreviations: bp, B-pleurotergites; cp, caudal pleurotergite; rt, ring tergite; ts, telson sclerite; tt, T-tergite. Scale bars represent: 5 mm (A, F– I); 2 mm (B–E, J). (Image by NIGPAS)
