Susceptibility of Gecko Cell Line for Cultivation and Adaptation of Infectious Bursal Disease Virus as an Experimental Vaccine. [PDF]

open access: yesVet Med Sci
First successful cultivation of IBDV on reptile‐derived Z1 cells yields high‐titre virus and induces immunity in chickens. This scalable, egg‐free platform offers a promising alternative for vaccine production, leveraging evolutionary kinship between reptiles and birds for next‐generation poultry disease control.

The holotype of the basal archosauromorph Prolacerta broomi revisited [PDF]

open access: yesActa Palaeontologica Polonica, 2023
Prolacerta broomi is one of the most important of fossil reptiles. First considered as one of the earliest members of squamates, this basal archosauromorph has been used as a model for diapsid morphological evolution ever since its discovery, playing ...

Trifold origin of the reptilian ear ossicle and its relation to the evolutionary modification of the temporal skull region. [PDF]

open access: yesJ Anat
The columella‐complex in reptile middle ears involves the footplate, columella shaft, and extracolumella. The latter is partly of quadrate developmental origin, whereas the footplate derives from the mesodermal otic capsule, the shaft and another part of the extracolumella from the hyoid arch.

CARINTHIASUCHUS KANDUTSCHI, A NEW ARCHOSAUR (REPTILIA: DIAPSIDA) FROM THE TRIASSIC OF AUSTRIA

open access: yesRivista Italiana di Paleontologia e Stratigrafia
A partial skeleton of a small reptile with a distinctive maxilla, dentition, caudal vertebrae and osteoderms from the marine Partnach Formation (Ladinian-earliest Carnian) near Jadersdorf (Gitschtal, Hermagor) in the Gailtal Alps of Carinthia (Austria),

Colobops: a juvenile rhynchocephalian reptile (Lepidosauromorpha), not a diminutive archosauromorph with an unusually strong bite [PDF]

open access: yesRoyal Society Open Science, 2020
Correctly identifying taxa at the root of major clades or the oldest clade-representatives is critical for meaningful interpretations of evolution. A small, partially crushed skull from the Late Triassic (Norian) of Connecticut, USA, originally described

The evolution of muscle spindles. [PDF]

open access: yesExp Physiol
Abstract Muscle spindles are stretch‐sensitive mechanoreceptors found in the skeletal muscles of most four‐limbed vertebrates. They are unique amongst sensory receptors in the ability to regulate their sensitivity by contraction of the intrafusal muscle fibres on which the sensory endings lie.
