“…There are multiple problems with calibrating molecular phylogenies using the published literature on fossil snakes (Head, 2015), especially for caenophidians: The absence of discrete apomorphies in vertebral morphology for most taxa limits testable, reproducible taxonomic hypotheses from isolated fossils. Additionally, considerable intracolumnar, individual, and ontogenetic variation exists in vertebral morphology, and very few studies have attempted to examine the influence of these factors in taxonomic assignments (Szyndlar, 2012 [but see Szyndlar, 1984 andLaDuke, 1991a for analyses of intracolumnar and individual variation]).…”

Calibrations published in the Fossil Calibration Series are accessioned into the Fossil Calibration Database (www.fossilcalibrations.org). The Database is a dynamic tool for finding up-to-date calibrations, and calibration data will be updated and annotated as interpretations change. In contrast, the Fossil Calibration papers are a permanent published record of the information on which the calibrations were originally based. Please refer to the Database for the latest data.

The taxonomy of the early Miocene genus Pseudoepicrates is controversial. Originally interpreted as the viperid Neurodromicus, subsequent work deemed the material to represent an extinct boid, Pseudoepicrates stanolseni. However, more recent work considered Pseudoepicrates to be a synonym of the extant Boa constrictor. Due to these conflicting interpretations, we provide a revision of the systematic affinities of P. stanolseni. This redescription was based on the first-hand analysis of all material of Pseudoepicrates, together with the comparison of extant boids. Our findings suggest that, in addition to being an invalid taxon, 'Pseudoepicrates' cannot be referred to B. constrictor. Instead, the extant Chilabothrus is here regarded as the most cogent generic assignment, with Chilabothrus stanolseni comb. nov. proposed for the extinct species. The referral of this material to Chilabothrus suggests that the genus originated as early as ~18.5 Mya. The revised history of this record has interesting implications for our understanding of the early divergence of the group. The presence of Chilabothrus in the early Miocene of Florida supports biogeographical hypotheses, which suggest that the genus reached the West Indian island complex around 22 Mya, dispersing into the North American territory by at least 18.5 Mya.

“…eral anguimorph clades (e.g., Anguidae, Gerrhonotinae, Diploslossinae, Anguinae, Xenosaurus) is consistent. Thus, many apomorphies are stable between analyses, and fossils can be placed in molecular topologies with some care and attention to which clades are congruent between topologies and which clades are not (Head, 2015). Here, I provide conclusive evidence for the first known occurrence of the gerrhonotine Elgaria.…”
