lepospondyl /ˌlɛpə(ʊ)ˈspɒndɪl /nounAn early fossil amphibian of the Carboniferous and Permian periods, distinguished by vertebrae shaped liked hourglasses.- Microsauria and related orders, formerly placed in the subclass Lepospondyli.
In some lepospondyls, and in frogs and salamanders, the surangular is absent....- At this point, temnospondyls, lepospondyls and reptilomorphs diverged.
- This may be supported by the observation that in other elongate lepospondyls showing limb reduction there is first a reduction in the number of digits and the size of the limb.
Origin 1930s: from modern Latin Lepospondyli (plural), from Greek lepos 'husk' + spondulos 'vertebra'. |
