dc.description.abstract "Shared derived characters of the basicranium provide the basis for a new theory of relationships and a new classification of the major groups of living and extinct turtles. Post-Triassic turtles are characterized by a jaw-closing mechanism where the main adductor tendon rides over a trochlea, a condition unique among vertebrates. A study of the trochlear mechanism and associated basicranial adaptations for akinesis suggests that the trochlea evolved independently in cryptodires and pleurodires. Cranial arteries and the canals and foramina associated with them provide characters used to develop hypotheses of relationships among the Cryptodira. The taxon 'Amphichelydia,' characterized by primitive features and supposedly containing the ancestors of recent turtles, is rejected and its members distributed to monophyletic taxa"--P. 391. en_US

Files in this item

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
