Liu and Bever 2018
describe a complete pareiasaur skull close to Eliginia (Fig. 1), the proximal outgroup to hardshell turtles in the large reptile tree, and no where else. The new specimen is significantly larger than Elginia. The authors refer the specimen to Sanchuansaurus, a taxon apparently known from far less material. Evidently this abstract does not represent the earlier Eliginia wuyongae (Fig. 1), which is not significantly larger than Elginia. Liu and Bever make no mention of the eliginiid relationship to basal hard-shell turtles.
Figure 1. Another gap is filled by nesting E. wuyongae between Bunostegos and Elginia at the base of hard shell turtles in the LRT. The new specimen is larger than Eliginia.
