Phylogenetically‐informed estimates of notosuchian (Archosauria, Crocodylomorpha) body size and the challenges of inferring macroevolutionary patterns in extinct groups

Palaeontology, Volume 69, Issue 3, 2026.
Abstract Notosuchian crocodylomorphs were predominantly active terrestrial predators, exhibiting a wide range of ecomorphological specializations and body sizes. Given that body size plays an important role in the life history of vertebrates, its accurate estimation for notosuchians is crucial for understanding macroevolutionary and macroecological ...

Endocast and bony labyrinth of a Devonian ‘placoderm’ challenges stem gnathostome phylogeny [PDF]

, 2021
Our understanding of the earliest evolution of jawed vertebrates depends on a credible phylogenetic framework for the jawed stem gnathostomes collectively known as ‘placoderms’.

A new selenosteid placoderm from the Late Devonian of the eastern Anti-Atlas (Morocco) with preserved body outline and its ecomorphology

Frontiers in Ecology and Evolution, 2022
Placoderms are an extinct group of early jawed vertebrates that play a key role in understanding the evolution of the gnathostome body plan, including the origin of novelties such as jaws, teeth, and pelvic fins.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Neurocranial anatomy of an enigmatic Early Devonian fish sheds light on early osteichthyan evolution

eLife, 2018
The skull of ‘Ligulalepis’ from the Early Devonian of Australia (AM-F101607) has significantly expanded our knowledge of early osteichthyan anatomy, but its phylogenetic position has remained uncertain.

Early Gnathostome Phylogeny Revisited: Multiple Method Consensus. [PDF]

PLoS ONE, 2016
A series of recent studies recovered consistent phylogenetic scenarios of jawed vertebrates, such as the paraphyly of placoderms with respect to crown gnathostomes, and antiarchs as the sister group of all other jawed vertebrates.
