Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. L. Georgalis et al. 2016 | Taking into account the new specimen, L. crotaloides can be referred to the Viperidae on the basis of the proportionally wide cotyle and condyle (the latter of which is quite robust), the probable presence of hypapophysis, a relatively short centrum and, above all, the dorsally tilted prezygapophyseal facets |
