Description	By 98 hpf, Meckel’s cartilage (Mk), the palatoquadrate (pq), the dentary (d), and the maxilla (mx) are visible. The dentary follows the contour of Meckel’s cartilage posterolaterally, projecting away from the cartilage ventrally. GFP-positive chondrocytes span the mandibular symphysis (sym), where cells are positioned ventrally relative to the trajectory of the main body of Meckel’s cartilage.
