A summary of the Paleozoic biostratigraphy and re-examination of palynology samples from the 9590 to 10 000 ft. (2923.0–3048.0 m) interval of the Gannet O-54 well, Grand Banks of Newfoundland / N. Bingham-Koslowski... : M183-2/8819E-PDF

"Five unoxidized palynological (kerogen) slides from the lowermost section of the Gannet O-54 well (part of the Geological Survey of Canada – Atlantic's archived slide collection) were re-analyzed with the hope of providing refined ages for this mainly indeterminate interval: slides P3580-07 (9590'/2923.0 m), P3581-07 (9690'/2953.5 m), P3582-07 (9790'/2984.0 m), P3583-07 (9890'/3014.5 m), and P3584-07 (10 000'/3048.0 m). Thermal alteration indices (TAIs) were also measured where possible. Three of the slides are barren (P3581-07, P3583-07, and P3584-07). One slide (P3582-07) contains two spores: Middle to Late Devonian Ancyrospora sp. with a TAI value of 6+ and an indeterminate spore with a TAI value of 5+. Both spores are interpreted as caved and thus not useful in determining age. Only one slide, P3580-07 (9590'/2923.0 m), yields in situ, identifiable spores, indicating a Middle to Late Devonian age, which is consistent with previously published palynological data for Gannet O-54"--Abstract.
