IVPP V14979.1–4 (four articulated skeletons, belonging to individuals of different ages, are preserved on a slab); IVPP V14979.5 and IVPP V14979.6 (additional slab, approximately half of the size of the former, bears mainly disarticulated bones and two partially articulated skulls exposed in ventral aspect); Four developmental stages can be recognized on the first slab: early post-metamorphic juvenile (IVPP V14979.4); late post-metamorphic juvenile (IVPP V14979.3); early adult (IVPP V14979.2); and fully grown adult (IVPP V14979.1). The two partially preserved skulls on the additional slab (IVPP V14979.5 and IVPP V14979.6) belong to late post-metamorphic juveniles. Five additional skeletons from the same locality and horizon that are preserved on separate slabs represent early adults (IVPP V13236, IVPP V13245, IVPP V13380) and fully grown adults (IVPP V13238, IVPP V13239). | ||||||||||
