Cannosphaeropsis pusulosa
Cannosphaeropsis pusulosa, Morgenroth, 1966
Now Trabeculidium. Originally Cannosphaeropsis, subsequently Nematosphaeropsis, thirdly (and now) Trabeculidium.
Holotype: Morgenroth, 1966, pl.2, fig.6
Age: Early Oligocene
Original description Morgenroth 1966
Derivatio nominis: pusulosus Latin = full of bubbles Holotype: That in Slide H 17 preserved specimen shown on plate 2 Fig. 6. Paratypoids: H 3丨I,H3/II, HS, H10, H107.
Locus typicus: Depold'sche Ziegelei (south of Helmstedt).
Stratum typicum: Lower Oligocene.
Diagnosis: A species of the genus Cannosphaeropsis with a usually clearly ellipsoidal capsule and slender, branching processes, the branches of which are distally connected to each other by very delicate threads. Bubble-shaped, hollow protuberances on the capsule are characteristic.
Description: The usually clearly ellipsoidal, but sometimes also spherical capsule has a delicate wall. Numerous very slender, massive processes rise from the smooth capsule surface, at the base of which there are occasionally relic-like ridges. The processes often divide into halves and split distally into 4-7 side branches, which are connected to each other by the finest cords, so that a relatively large-mesh outer network is created. Each of the available specimens has bubble-like, mostly elongated, hollow growths on the capsule (pyrite deposits!). These growths appear to be characteristic of the species. - None of the specimens has a pyloma.
Dimensions:
Cyst body length: 39µ (28µ–47µ)
Cyst body width: 31µ (28µ–42µ)
Cyst length: 77µ (65µ–98µ)
Cyst width: 71µ (59µ–84µ)
(50 measurements)
Number of examined specimens: 98
Comparisons: None of the previously known Cannosphaeropsis species has similar characteristic protuberances. - The Cannosphaeropsis sp. The specimen described from the North German Eocene is identical to the newly discovered objects.
