Frugivory and Seed Dispersal by Crocodilians: An Overlooked Form of Saurochory?

, 2013
Saurochory (seed dispersal by reptiles) among crocodilians has largely been ignored, probably because these reptiles are generally assumed to be obligate carnivores incapable of digesting vegetable proteins and polysaccharides.

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

The Anatomical Record, Volume 309, Issue 10, Page 2725-2738, October 2026.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, Volume 309, Issue 10, Page 2752-2789, October 2026.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, Volume 309, Issue 10, Page 2636-2655, October 2026.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Crocodilians of the Crato Formation: evidence for enigmatic species

, 2007
Crocodilians are extremely rare in the Crato Formation, and most of the material that has been collected is fragmentary or badly preserved. Only two species are represented, both of which are enigmatic concerning both their preservation and anatomy. Only

Live birth in an archosauromorph reptile

Nature Communications, 2017
Although live birth evolved repeatedly in other clades, it has not been found in archosauromorphs, the group including modern birds and crocodilians. Here, the authors describe a fossilized pregnantDinocephalosaurusfrom ∼245 million years ago, providing ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, Volume 309, Issue 10, Page 2560-2573, October 2026.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Cytochrome oxidase I DNA barcodes of crocodilians meat selling in Hong Kong

Scientific Data
The crocodilians include true crocodiles, alligators, caimans, and gharial, and the trade of crocodilian products is regulated in accordance with the Convention of Wild Fauna and Flora (CITES). Hong Kong does not have her own wild crocodilians; thus, all

Development of Thalamo‐Telencephalic Circuits in a Reptile

Journal of Comparative Neurology, Volume 534, Issue 10, October 2026.
The development of forebrain connections was investigated in the Alligator. Four circuits were identified: ipsilateral basal nuclei to the dorsal thalamus, ipsilateral lateral forebrain bundle, and ipsilateral and contralateral medial forebrain bundle.
