Echinofulgur helenae (Olsson, 1967)
Statigraphy: Pinecrest Sand Member of the Tamiami Formation
Location: APAC Pit Bed 4, Sarasota County, Florida USA.
Notes: More variable that E. echinatum, E. helenae is the common Echinofulgur in the lower beds of the Pinecrest. Ranges from tall straight individuals similar to E. echinatum to short stubby forms reminiscent of Tropochasca petiti. A row of spines on the siphonal canal distinguishes it from E. echinatum.
