Thiry et al (2025) Supplement #1-JASRep

The opportunity to undertake 3D photogrammetric surveys arose during the revision of the manuscript. We wanted to take advantage of this opportunity to explore a better accounting of the volumes of the LFO 1 cavity and the LFO 2 hole. Unfortunately, the small size of the cavity combined with numerous pronounced and narrow re-entrant structures generated lighting problems and we have not yet assembled a complete 3D model of the cavity. We present here the images of the LFO 2 hole which provide additional insights to those given in Figures 5B and 6F of the article.
