Texasophis wilsoni Holman 1984

Conservation Status:


Vertebra differs from those of other species of the genus (undescribed new Texasophis species from the Oligocene of Colorado and Miocene of France, and T. fossilis Holman of the Miocene of Texas) in the following combination of vertebral characters: 1) it is the largest known form (total length 6.4 mm), 2) its neural spine is well-developed, 3) its neural arch is moderately vaulted, 4) its hemal keel is not widened posteriorly and 5) its hemal keel is narrower than in T. fossilis.
