Texas Echinoid Fossil

Unidentified echinoid found in Fort Worth, Texas. It is existed in the Cretaceous Period.  My guess is it has the word aster in its name.

UPDATE (March 2020): This might be an Epiaster whitei? from the Kiamichi Formation of Denton County. Fort Worth is a very large area and exists in four counties (Tarrant, Denton, Parker, Wise).
