metadata.name: dc.description.abstract
metadata.value: Neruchella eichwaldi gen. et sp. nov. is erected on the basis of a head shield
  found in the Famennian Lebedyanian Regional Stage of the Orel Region, Russia.
  The new taxon differs from all known ptyctodontids, and is characterized by the
  central plates in contact along the skull midline, the meeting of the sensory-line
  canals on the centrals and the loss of the nuchal plate. The structures of the
  head shields of two Famennian ptyctodontids Neruchella and Chelyophorus are
  completely different from the general skull bone pattern of older ptyctodontid
  taxa.
