|Distribution||Upper Carboniferous (Kasimovian) of Texas, USA.|
|Type||Elliptechinus kiwiaster Schneider, Sprinkle & Ryder, 2005, p. 757, by original designation. Holotype, Texas Memorial Museum 1967TX23a.|
|Classification and/or Status||Stem group Echinoidea; Lepidocentridae.
Monotypic; possibly only a subgenus of Pholidechinus.
|Remarks||This taxon was recently described and figured in excellent detail by Schneider et al. (2005). They recognized that it was closest to Pholidechinus but distinguished it on the basis of its slightly more unequal-sized tubercles on interambulacral plates and its more extreme offsetting of pore-pairs and adradial pinching of every second plate. However, these differences are slight and separation from Pholidechinus is hard to justify.
