| Tubicamara coriacea Kozłowski, 1949 |
The camaroid graptolite Tubicamara coriacea
Kozłowski was described from the upper
Tremadocian cherts of Wysoczki, Świętokrzyskie
Mts (=Holy Cross Mts.), Central Poland.
All specimens of this graptolite found up to now
are tiny fragments of rhabdosomes composed of
a few autothecae embedded in abundant
extracamaral tissue. The autothecae are sharply
differentiated into two parts, a camara (an
inflated basal vesicle) and a funnel-like collum (a
free tube corresponding to the free portion of
the autothecae in Tuboidea) with ventral
apertural process. There are no traces of
bithecae in T. coriacea.
The genus Tubicamara has been assigned by
Bulman (1955) to the family Cysticamaridae.
