One of those fragments corresponds to the left prezygapophysis and parapophysis
of a middle or a posterior dorsal vertebra.
After the involved parapophysis
was removed 1-2 ribs near the spine were further removed and intercostal neurovascular bundles were ligated and severed.
The posteroventral surface of the post-temporosupracleithrum is weakly attached, by means of connective tissue, to the anteroventral process of the fourth parapophysis
(Mullerian process), which is well-developed and exhibits a highly mobile, oval ventrolateral tip.
Although the transverse processes are incomplete on SEKI-20167, they are preserved at the proximal end showing that the diapophysis and parapophysis are likely joined.
The parapophysis is offset caudally from the diapophysis on SEKI-20167.
The conclusion that the diapophysis and parapophysis processes are joining implies that SEKI-20167 could belong to Aneides ferreus/vagrans or some species within Plethodon.
The diapophysis and parapophysis are connected to the tip, indicating that SEKI-20166 does not belong to Ensatina, Aneides ferreus/vagrans, Hydromantes, or some species of Plethodon.
First haemal arch emanating from first caudal vertebra, anterior parapophysis directed ventromedially to fuse with contralateral structure, produced as haemal spine.
First epipleural contacting dorsolateral aspect of parapophysis of third vertebra, coursing posterodorsally to ribs.
Vertebrae 9 + 16 + hypural = 26; parapophysis
developed from the sixth vertebra, its processes widely diverging, directed outward and downward.
Other associated skeletal material includes four disarticulated abdominal vertebral centra with the parapophysis
either poorly preserved or broken.
