Fig. 7From: Sequence of chondrocranial development in basal anurans—Let’s make a craniumD. scovazzi, development of the cartilaginous head skeleton of larvae after all major cartilages are present. Note the development of the synotic tectum and the quadratoethmoid process as well as the closure of the basicranial fenestra. Shown are cleared and stained specimens of stage Go28 (a), Go32 (b) and Go34 (c) Scale bars indicate 0,5 mm. amc, admandibular cartilage; bf, basicranial floor; jf, jugular foramen; mtt, medial tectal taenia; qp, quadratoethmoid process; st, synotic tectumBack to article page
