Fig 4. Partial skeleton of Antaecetus aithai, specimen FSAC Bouj-200, as collected and preserved in three blocks of sediment.

Each block was turned before preparation and then cleaned to expose the underside of the block, which is the side shown here. The cranium is shown in red, teeth in brown, vertebrae in blue, left ribs in orange, and right ribs in yellow. Thoracic vertebrae are numbered from T2 through T11 on the assumption that the skeleton had 13 thoracics. Lumbar vertebrae are numbered from L1 through L10. There may have been more than 13 thoracics, and there may have been more than 10 lumbars.
