Description Piero, N. del, Rigaud, S., Martini, R. (2022). Taanella Yukonensis n. gen. n. sp., a Uniquely Perforate Agglutinated Foraminifer from the Upper Triassic of Panthalassa (Lime Peak, Yukon, Canada). Journal of Foraminiferal Research. 52: 99-107., available online at https://doi.org/10.2113/gsjfr.52.2.99page(s): p. 101, Figs. 2.1–2.12 (holotype fig. 2.1).
Lime Peak, Yukon, Canada (Aksala Fm., Lewes River Group, upper Norian). 1 Holotype, 2-12 Paratypes. 1 Axial subcentered section showing the aperture opening in the umbilical area (white arrowhead, sample WH 193, collection no. MHNG-GEPI- 2022-01); 2 Transverse section showing that the inner part of the umbilicus is filled with wall material (i.e., the deep umbilicus does not reach the proloculus, white arrowhead). Foramina (black arrowheads) and wall pores are well-visible (sample WH 389, collection no. MHNG-GEPI-2022- 02); 3 Specimen attached (in life position; white arrowhead, sample WH 232_B, collection no. MHNG-GEPI-2022-03); 4 Subaxial, slightly oblique section showing the wall perforations (black arrowheads; sample WH 191, collection no. MHNG-GEPI-2022-04); 5 Oblique section showing the foramina (white arrowheads) and the deep sutural slits (black arrowheads; sample WH 97, collection no. MHNG-GEPI-2022-05); 6 Basal section showing the hollow umbilicus (white arrowhead) and the sutural slits (black arrowheads; sample WH 80, collection no. MHNG-GEPI-2022-06); 7 Tangential section clearly showing the connection between two chambers (foramen, white arrowhead; sample WH 191, collection no. MHNG-GEPI- 2022-04); 8 Oblique section showing the hollow umbilic (white arrowhead) and wall perforations (sample WH 193, collection no. MHNG-GEPI- 2022-01); 9 Slightly oblique, almost basal section, showing the hollow umbilicus (white arrowhead) and wall perforations (sample WH 193, collection no. MHNG-GEPI-2022-01); 10 Tangential section showing the coarsely porous, reticulate (white arrowheads) test (sample WH 193, collection no. MHNG-GEPI-2022-01); 11 Section tangential to the second whorl chamber’s wall showing how coarse the wall perforations are (sample WH 234, collection no. MHNG-GEPI-2022-07); 12 Subaxial, slightly oblique section showing the aperture (black arrowhead) and wall perforations (white arrowheads; sample WH 235, collection no. MHNG-GEPI-2022-08).
