Extended Data Fig. 9 | Estimates of the osteological range of motion. Extension and flexion of the preserved portion of vertebral column of Perucetus colossus holotype (MUSM 3248) is compared with an equivalent vertebral column portion of Cynthiacetus peruvianus holotype (MNHN.F.PRU10) using the respective 3D models.Intervertebral spaces were reconstructed based on the common dolphin (Delphinus delphis)81 (see Methods). Scale bar = 50 cm.
