Development of the pelvis and posterior part of the vertebral column in the Anura
Original language description
The anuran pelvic girdle is unique among all amphibians in that its acetabular portion is located far posterior to the sacrum, lateral to the postsacral (= caudal) vertebral column which is reduced to a single rod-like element called the urostyle. This situation in the adult is strikingly different not only from that in ancestral temnospondyls but also in other modern amphibians. Since there is no fossil which would document this evolutionary anatomical modification except for Triadobatrachus, the onlydata may be inferred from development in modern anurans. We chose 7 anuran species (belonging to genera Discoglossus, Bombina, Pelobates, Bufo, Rana, Xenopus) representing principal locomotory types (saltation, swimming, crawling, burrowing). Developmentof the pelvic girdle was studied on cleared-and-stained whole mounts and partly on serial histological sections. The basic developmental pattern was similar on all species ? the pelvis on both sides develops from two centres.
