Diagnosis
ReferenceDiagnosis
S. Onary et al. 2021Relatively small snake (~1.2 m,fide Marsh1871) distinguished from all other ophidians in possessing the following unique combination of vertebral features: small vertebral size (centrum length not exceeding 10 mm); absence of prezygapophyseal accessory processes; dorsoventrally low and short neuralspine that arises from the middle of the neural archextending longitudinally to the posterodorsal notch; dis-tinct median lobe between zygosphene articular facets;posterior trunk vertebrae with deep paralymphatic fossaeand paradiapophyses in anterior view extending laterally to the same level as the prezygapophyseal articular facet’s tip.
