Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 2100-2123, August 2026.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 1995-2048, August 2026.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Shaping Performance of XP4 versus ProTaper Next in C‐Shaped Canals: A Micro‐CT Study of 3D‐Printed Mandibular Second Molar Replicas

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Introduction This micro‐computed tomography (micro‐CT) study aimed to evaluate the shaping ability of two nickel–titanium (NiTi) rotary systems—XP4 and ProTaper Next (PTN)—in 3D‐printed replicas of C‐shaped canals. Methods Two extracted mandibular second molars with C‐shaped root canals—one continuous (Melton's Category I) and one ...

Morphological Characterization and Complete Mitochondrial Genome of a New Epizoic Hexamerous Brittle Star Gymnolophus sexradia sp. Nov

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...
