Ontogenetic variability of the intertympanic sinus distinguishes lineages within Crocodylia. [PDF]

open access: yesJ Anat, 2023
We recognised the usefulness of the paratympanic sinuses in distinguishing major lineages within Crocodylia. 3D geometric morphometric approaches allow us to quantify the ontogeny and variability of the intertympanic sinus within one of the largest dataset of modern species, including one of the largest specimens ever scanned at such a high resolution.

Pseudosuchian thermometabolism: A review of the past two decades. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Pseudosuchia, one of the two main clades of Archosauria, is today only represented by some 20 extant species, the crocodilians, representing only a fraction of its extinct diversity. Extant crocodilians are ectotherms but present morphological and anatomical features usually associated with endothermy.

Convergence and functional evolution of longirostry in crocodylomorphs

open access: yesPalaeontology, Volume 62, Issue 6, Page 867-887, November 2019., 2019
Abstract During the Mesozoic, Crocodylomorpha had a much higher taxonomic and morphological diversity than today. Members of one particularly successful clade, Thalattosuchia, are well‐known for being longirostrine: having long, slender snouts. It has generally been assumed that Thalattosuchia owed their success in part to the evolution of longirostry,

Exploring the effects of weighting against homoplasy in genealogies of palaeontological phylogenetic matrices

open access: yesCladistics, Volume 40, Issue 3, Page 242-281, June 2024.
Abstract Although simulations have shown that implied weighting (IW) outperforms equal weighting (EW) in phylogenetic parsimony analyses, weighting against homoplasy lacks extensive usage in palaeontology. Iterative modifications of several phylogenetic matrices in the last decades resulted in extensive genealogies of datasets that allow the evaluation
