First known trace fossil of a nesting iguana (Pleistocene), The Bahamas.

open access: yesPLoS ONE, 2020
Most species of modern iguanas (Iguania, Iguanidae) dig burrows for dwelling and nesting, yet neither type of burrow has been interpreted as trace fossils in the geologic record.

A description of dental microanatomy and implantation geometry in Chamaeleonidae

open access: yesJournal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

Phylogenetic Reconstruction of Lung Evolution in Extant Squamata

open access: yesJournal of Zoology, EarlyView.
The Squamata group exhibits remarkable diversity in lung structure. However, a comprehensive understanding of how this variation evolved within the clade is still lacking. To reconstruct the evolutionary history of lungs of living squamates, we conducted comparative phylogenetic analyses using categorized lung traits, such as lung type, respiratory ...

Where Lineages Persist: Phylogenetic Patterns and Evolutionary Vulnerability in South Africa's Herpetofauna

open access: yesDiversity and Distributions, Volume 32, Issue 8, August 2026.
ABSTRACT Aim Conservation under the current global biodiversity crisis demands strategic prioritisation to maximise the impact of limited resources. This study aims to integrate evolutionary history, an often‐overlooked component of biodiversity, alongside extinction risk to identify priority species and regions, assessing both the feasibility and ...

Evolution of sexual dimorphism in the digit ratio 2D:4D--relationships with body size and microhabitat use in iguanian lizards. [PDF]

open access: yesPLoS ONE, 2011
The ratio between lengths of digit II and IV (digit ratio 2D:4D) is a morphological feature that likely affects tetrapod locomotor performances in different microhabitats. Modifications of this trait may be triggered by changes in steroids concentrations

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 1002-1025, June 2026.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...
