Desertiguana gobiensis gen. et sp. nov., a new lizard (Phrynosomatidae, Iguanomorpha) from the Upper Cretaceous of Mongolia
@article{Alifanov2013DesertiguanaGG, title={Desertiguana gobiensis gen. et sp. nov., a new lizard (Phrynosomatidae, Iguanomorpha) from the Upper Cretaceous of Mongolia}, author={Vladimir R. Alifanov}, journal={Paleontological Journal}, year={2013}, volume={47}, pages={417-424} }
A new lizard, Desertiguana gobiensis gen. et sp. nov., is described based on a left mandibular fragment from the Upper Cretaceous of Mongolia. Comparative analysis of mandibular structures shows that it belongs to the family Phrynosomatidae sensu Frost et Etheridge, 1988. Some questions of relationships of this family with other Iguanomorpha (Iguanidae sensu lato) are discussed.

Fossil calibration dates for molecular phylogenetic analysis of snakes 1: Serpentes, Alethinophidia, Boidae, Pythonidae
- Environmental Science

Comparisons of phylogenetically justified calibrations with published studies that employed form-taxon assignments suggests greatly younger divergences for justified nodes and indicates that deep-time divergence estimates that have been correlated with tectonic histories may be considerably too old and reliant on presumptions of Early Cretaceous Gondwanan vicariance as a mechanism of speciation.

The present work reevaluate all thirty calibrations in detail, present the current state of knowledge on them with its various uncertainties, rerun the dating analysis, and conclude that calibration dates cannot be taken from published compendia or other secondary or tertiary sources without risking strong distortions to the results.
