Cribellopora trasoni View in CoL sp. n.
Pl. 122, Fig. 1-3
D i a g n o s i s: Colony encrusting. Autozooecia oval with small cribellate frontal pores. Lateral walls indistinct. Aperture semilunar with a very narrow sinus, no oral spines. Ovicell flat with a smooth, nonporous frontal wall.
H o l o t y p e: The specimen illustrated on Pl. 122, Fig. 2-3 from the section Kralice nad Oslavou, deposited in the NM Prague under the number PM2-P 01505
P a r a t y p e s: The specimen from the section Kralice nad Oslavou, deposited in the NM Prague under the number PM2-P 01924
D e r i v a t i o n o m i n i s: Derived from the name Třasoň, a student who studied the section at Kralice nad Oslavou.
L o c u s t y p i c u s: Kralice nad Oslavou, sample-4, which corresponds to sample KRA-S 3 ( Zágoršek et al., 2009).
S t r a t u m t y p i c u m: Langhian – Lower Badenian..
M e a s u r e m e n t s: (in micro meters = µm; x = = average):
length of autozooecia: 604-719; x = 677
width of autozooecia: 455-515; x = 475
length of autozooecial aperture without sinus:
102-129; x = 114
length of autozooecial aperture with sinus:
147-182; x = 167
width of autozooecial aperture: 146-156; x = 150
length of ovicell: 257-373; x = 302
width of ovicell: 311-387; x = 349
D e s c r i p t i o n: Colony encrusting, autozooecia grow in rather regular rows. Autozooecia usually oval or slightly hexagonal, longer than wide, separated by deep furrows. Frontal wall convex, smooth, slightly perforated by scattered, cribellate frontal pores. Lateral walls indistinct. Aperture semilunar to semicircular with a very narrow sinus, preserved almost as only a slit. No oral spines observed. Ovicell flat, slightly immersed into the distal part of the autozooecium with a smooth, nonporous frontal wall. Marginal pores on the ovicell not developed.
C o m p a r i s o n: This species differs from Cribellopora latigastra ( DAVID, 1949) in having small frontal pores, ovicells without lateral pores and a very narrow sinus. The exact shape of the frontal pores is – due to the preservation – not clearly visible, but they are smaller than in Cribellopora latigastra . Cribellopora hluchovensis sp. n. also has a wide sinus and ovicells with lateral pores.
R e m a r k: Due to the presence of cribellate frontal pores, a narrow sinus and absence of oral spines this species belongs to Cribellopora as described by Gordon (1984).
O c c u r r e n c e: Only in the section at Kralice nad Oslavou.
