[Annelida] Tubes of Pectinariidae and Terebellidae

[Olev Vinn]

Dear annelidans,

I am currently studying a pectinariid-like agglutinated fossil tube from
the Cretacous. I asking your help regarding the possible morphological
difference between the agglutinated tubes made by Pectinariidae and
Terebellidae. Is it possible to distinguish Pectinariidae tubes from
Terebellidae tubes, based only on the tube?

Best wishes,

Olev
