dc.description.abstract "The Lysorophia is an order of small, but extremely elongate and tiny-limbed aquatic lepospondyl amphibians known from the Middle Pennsylvanian through the Lower Permian periods, primarily in North America. The order comprises one family, Cocytinidae, with three recognized species: Brachydectes newberryi (= Cocytinus gyrinoides), B. elongatus (= Lysorophus tricarinatus, partim), and Pleuroptyx clavatus. Other named species are considered Lysorophia, incertae sedis. Members of the Lysorophia are distinguished by their fenestrate skulls, anteriorly sloping suspensoria, short mandibles (each bearing a lateral mandibular fenestra), and extensive, well-ossified hyobranchial skeletons. Presacral vertebrae are holospondylous and number between 69 (B. newberryi) and 97 (B. Elongatus). Neural arch halves are sutured at their midlines and to their centra. While closely similar to one another, lysorophoid species are highly derived relative to other Paleozoic amphibians. They are most closely related to microsaurs, judged principally through the morphology of the craniovertebral articulation"--P. 3. en_US

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.
