metadata.name: dc.description.abstract
metadata.value: KOKM A, the associated caudal vertebrae of a sauropod from the Lower Cretaceous
  (Aptian) Ilek Formation at Shestakovo 3 locality in Kemerovo–Kuzbass
  oblast, Western Siberia, Russia, shows a unique combination of derived caudal
  vertebrae and plesiomorphic and highly diverse haemal arches (chevrons). The
  anterior, middle, and posterior caudal vertebrae are deeply procoelous with a
  ball-like posterior condyle. There are five type of chevrons: closed Y-shaped anterior
  chevrons with a small haemal canal, closed asymmetric middle chevrons
  with a small ventral slit, open forked middle chevrons with large ventral slit,
  separate posterior chevrons with chevron facets, and separate posterior rodlike
  chevrons without chevron facets. The equal weight and extended implied
  weighting parsimony analyses place KOKM A within Turiasauria and Titanosauria,
  respectively. Both these analyses place Sibirotitan astrosacralis from the
  nearby Shestakovo 1 locality of the same stratigraphic unit in Mamenchisauridae.
  Both equal weight and extended implied weighting analyses combining
  S. astrosacralis and KOKM A in a single terminal taxon place it as a non-lithostrotian
  titanosaur, in particular, as a sister taxon for Daxiatitan binglingi from the
  Lower Cretaceous of China. D. binglingi is similar to S. astrosacralis and KOKM A
  in structure of cervical and caudal vertebrae, respectively. This suggests attribution
  of KOKM A to S. astrosacralis.
