Glyptodendron is a Lower Silurian westonocerid characterized by compressed cyrtocones with a narrowly rounded dorsum and greatest width in the ventrolateral region. Sutures slope forward from the dorsum which is on the longitudinally concave side. The siphuncle is slightly ventral from the center. Segments are subspherical in the young; equally b road but shorter in the adult. No endosiphuncular deposits are known. The surface of the shell is covered by obliquely intersecting rows of scale-like pits.
