Jerea quenstedti ?
Zittel 1878
Jerea quenstedti is a rare species at Misburg.
The two specimens shown are probably Jerea quenstedti, having a typical fig-shaped main body, a stout stem, and several deep grooves radiating away from the top center. The surface is furnished with numerous irregularly distributed ostia of variable size. The paragaster area is not well preserved in either of the specimens, and the cortex (if once present) has been lost.
The specimen in the first picture is broken in two parts. Stem and top section have been rotated to show best preserved sides.
A second sample of Jerea quenstedti, showing ostia and grooves.
The main skeleton consists of large, smooth tetraclones. The dermal scleres are dichotriaenes.
The picture shows
(a) tetraclones,
(b) dichotriaenes, and
(c) irregular siliceous bodies of the cortex.
