Hedinaspis sp. 2 — photo 1
Photo 1 · aspis, Greek, shield. In this species the glabella is stout, weakly expanded at the base, and of nearly uniform width; the preglabellar field is extremely short; the anterior branches of the facial sutures diverge at a large angle; the thorax has 28 segments. Xiang Liwen et al. (1985) assigned this species to Hedinaspis regalis; however, this species has a glabella of nearly uniform width, a weakly expanded base, and relatively larger palpebral lobes, on which basis it is treated as an unnamed species. Literature specimen (Xinjiang; Xiang Liwen et al. 1985) Injury-healed specimen (Zhejiang; StrongZJU)
