To Anna Fugagnoli,

Jurassic Glomospira along with Glomospirella are not particularly well
described groups, even though they can form important components of some
Middle and Upper Jurassic microfaunas. Many authors appear to use the taxa
Glomospira charoides and Glomsopira gordialis for lumping forms together.

Your best bets for specific descriptions and illustrations of Jurassic taxa are:
