The citation as it was given
The scientific publication of ROY OOSTHUIZEN's find. Dwykaselachus oosthuizeni, a shark-like fish of the Permian, about 280 million years old, found on the farm SWARTSKRAAL and named for him; CT-scanned by Dr Robert Gess in 2013, and the scan revealed the origin of the chimaeras. Until then the chimaeroid record was mostly isolated tooth plates. This is the citation STO-0004 needs - a family story with a Nature paper behind it. Via SRC-010. | [31 Jul 2026] CORRECTED: this row said the CT scan was made in 1993. It was 2013, on the micro-CT scanner at the University of the Witwatersrand's Evolutionary Studies Institute, and Gess did it because Michael Coates urged him to look at this particular nodule. Two independent accounts agree (Sci.News and the University of Chicago Medicine release, both Jan 2017). The twenty-year error mattered: it put the scan six years BEFORE Roy Oosthuizen died, when in fact it came fourteen years after. | Full authorship: Michael I. Coates, Robert W. Gess, John A. Finarelli, Katharine E. Criswell and Kristen Tietjen. The specimen is held by the South African Museum, Cape Town.
Kept verbatim. This project contradicts published genealogies and corrects a family's own oral tradition, so every claim has to be checkable by someone who was not in the room.
