Thank you for finding it, I must have read something from an entirely separate group, as instead of being released in 06, it was much closer to 2016 or so, and must not have been documented as well. This image is directly from the paper, and looking at the 4 images in the top-left corner, A through D, A and C are a normal chick, B and D are the altered embryos showing signs of either teeth or the root attachment points for teeth.
