The history, systematics, and nomenclature of Thalattosuchia (Archosauria: Crocodylomorpha) [PDF]

Zoological Journal of the Linnean Society
The use of more than one nomenclatural code is becoming increasingly common in some biological sub-disciplines. To minimize nomenclatural instability, we have decided to establish a higher level systematization for Thalattosuchia under both the ...

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

The Anatomical Record, Volume 308, Issue 2, Page 315-341, February 2025.
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.

Bone histology of Iberosuchus macrodon (Sebecosuchia, Crocodylomorpha) [PDF]

Lethaia, 2017
International audienceIberosuchus macrodon is a Cenozoic crocodyliform interpreted as a terrestrial, cursorial form. To assess whether this adaptation was accompanied by a high growth rate and an elevated resting metabolic rate (two features commonly ...

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae) [PDF]

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Palaeohistology of Macrospondylus bollensis (Crocodylomorpha: Thalattosuchia: Teleosauroidea) from the Posidonienschiefer Formation (Toarcian) of Germany, with insights into life history and ecology [PDF]

The Anatomical Record, Volume 308, Issue 2, Page 342-368, February 2025.
Abstract The Posidonienschiefer Formation of southern Germany has yielded an array of incredible fossil vertebrates. One of the best represented clades therein is Teleosauroidea, a successful thalattosuchian crocodylomorph group that dominated the coastlines.

A new teleosaurid (Crocodylomorpha, Thalattosuchia) from the Sibumasu Terrane of Southeast Asia and a taxonomic reassessment of Indosinosuchus [PDF]

PeerJ
We describe teleosaurid remains from the Middle to Upper Jurassic Khlong Min Formation at Ban Nam Pun in southern Thailand and define Indosinosuchus peninsularensis sp. nov. This new species is diagnosed by a unique combination of cranial and postcranial

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution [PDF]

Journal of Anatomy, Volume 248, Issue 6, Page 890-901, June 2026.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

The osteohistology of Orthosuchus stormbergi using synchrotron radiation microcomputed tomography [PDF]

Journal of Anatomy, Volume 247, Issue 3-4, Page 587-607, September/October 2025.
The osteohistology of Orthosuchus stormbergi is described for the first time. The primary bone tissue was lamellar bone. It had relatively thick bone walls, possibly indicating an aquatic lifestyle. Orthosuchus was a small bodied adult reaching a maximum body mass of about 1.2 kg.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia [PDF]

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all
