Close-up of image comprising the CT scan utilised in the present study (not to scale). a Cropped image; b image with interpretative drawing superimposed. The image shows a coronal (cross-sectional) cut through left costal 7 medially and costal 6 laterally. The suture between the costals extends not perpendicularly to the plane and is thus difficult to discern in the image. The rudimentary neural 7 is visible underneath the costals 7 that meet at the midline of the shell. The left xiphiplastron lies ventrally to costals 6 and 7
