Schizoblastus sp.
Blastoid
Mississippian
Fern Glen Formation
Jefferson, County
![]()
Note: This specimen was found in the "white" Fern Glen matrix,
which is adjacent to the typical "dark pink" matrix. I often refer
the "dark pink" matrix as "reddish." We have no idea what the
two colors represent. However, we all have seen radical color
differences side by side in other formations. I refer to where
these colors meet as a transitional zone.Thanks to Doug DeRosear for the positive identification
