Original Description

Translated using Google Translate original German below

In his work, 'Foraminifera and Ostracods from the Cretan Archipelagos of the Upper Bavarian Alps 1 (Dep. II Cl.K. Akad. Wiss. Munich, Bd. XXI, 1st Abth., P. 174, Plate 21, Fig. 42) JG Egger describes under the name Siderolina cenomana Schacko tiny shapes with a case diameter of 0.12-0.16 mm. ausdensenon Plattenauer marl from Disselbach. This form, however, differs from the typical Hantkenina (Schackoina) cenomana (Schacko) by their pronounced Hantkenina-like shell construction and the development of a fifth chamber. It may well be regarded as a transitional form between the Cretaceous Schackoina species and the Eocene true hantkenines. It is here for the above-mentioned Egger's Hantkenina (Schackoina) senoniensis nov. spec. proposed.

"In seiner Arbeit, 'Foraminiferen und Ostrakoden aus den Kreidemergeln der Oberbayerisehen Alpen 1 ( Abh. II. Cl. K. Akad. Wiss. München, Bd. XXI , 1. Abth., p. 174, Tafel 21 , Fig. 42) beschreibt J. G. Egger ünter dem Namen Siderolina cenomana Schacko winzige Formen mit einem Gehäusedurchmesser von 0.120.16 mm. ausdensenonen Plattenauer-Mergelnvom Disselbach. Diese Form unterscheidet sich aber von der typischen Hantkenina (Schackoina) cenomana ( Schacko ) durch ihren ausgesprochenen Hantkenina-artigen Schalenbau und der Entwicklung einer fünften KammerSie kann wohl als eine Übergangsform zwischen den kretazischen SchackoinaArten und den eozänen echten Hantkeninen aufgefasst werden. Es sei hier für die obenerwähnte Egger'sche Form Hantkenina ( Schackoina) senoniensis nov. spec. vorgeschlagen.

Editors' Notes
Montanaro Gallitelli (1955, p. 143): "Schackoina senoniensis (Thalmann), from the upper Senonian Pattenauer marl (Campanian; see Aurouze and de Klasz, 1954) of the Bavarian Alps. The only figure of this species, which is so important stratigraphically was given by Egger (1900) under the name of Siderolina cenomana Schacko. In 1932, Thalmann separated Egger's form as a new species, Hantkenina (Schackoina) senoniensis, but did not give any figures. In any case, the figure given by Egger (1900, pl. 21, fig. 42) represents a specimen with four less discrete chambers, and the description also indicates a variability of from three to five chambers in the final whorl. Egger's type collection was destroyed during World War II. De Klasz (Aurouze and de Klasz, 1954) did not collect samples from the type locality of Pattenau, but in the upper Campanian marl of Disselbach, east of Grub, on the Traun River, near Eisenarzt, he discovered specimens supposedly corresponding to Egger's species, and attributed them with doubt to Hastigerinella (Hastigerinoides) rohri Bronnimann. Because of the difference in the two localities, we cannot determine the identity of Egger's (and Thalmann's) species." [details]
