Syngastrioceras websteri

Three views of what I think now is Syngastrioceras websteri Titus 2000. The top two are latex casts of the external mold (bottom).

Eumorphoceras girtyi zone

I found a mold of either Eosyngastrioceras inexpectans or Syngastrioceras websteri in the E. girtyi zone yesterday. These two are nearly identical going by shell shape and ornamentation, the suture would really tell the story, but there are no sutures in fossils that only have external molds.
