Lower Carboniferous (Visean), England.
Cravenechinus uniserialis Hawkins, 1946, p. 195, by original designation. Holotype, BMNH E32370.
|Classification and/or Status||
|Remarks||Hawkins stated that there were probably 8 columns of ambulacral plates. Although only four are visible in the two columns preserved all have their pore-pairs obliquely angled in the same direction, indicating that all four columns belong to the same half ambulacrum. Although badly weathered, the one well preserved tubercle that remains appears to be imperforate, contrary to Hawkins' statement.
Distinguished from Xenechinus in having a greater number of ambulacral columns in each zone.
