Waving Through Ontogeny: The Larval Chondrocranial Development of Staurois parvus
International Journal of Zoology, Volume 2026, Issue 1, 2026.The vertebrate skull is a complex structure with diverse evolutionary and developmental patterns. Anuran chondrocranial development has been shown to deviate from generalized vertebrate trends, highlighting its evolutionary flexibility. This study investigates the chondrocranial development of Staurois parvus, a ranid frog, to provide insights into ...

Into the Light: Diurnality has Evolved Multiple Times in Geckos [PDF]
, 2015 Geckos are the only major lizard group consisting mostly of nocturnal species. Nocturnality is presumed to have evolved early in gecko evolution and geckos possess numerous adaptations to functioning in low light and at low temperatures. However, not all

The phylogeny of basal archosaurs [PDF]
, 1994 Archosaur systematics has received much attention from the mid 1970s and several influential works on this topic have emerged. As discrepancy exists among proposed phylogenies, some of the most important of the papers in question are assessed here ...

The evolution of muscle spindles
Experimental Physiology, Volume 110, Issue 10, Page 1401-1421, October 1, 2025.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.

Flesh and bone: The musculature and cervical movements of pterosaurs [PDF]
Anais da Academia Brasileira de CiênciasThe osteological variations present in the cervical vertebrae of pterosaurs represent changes in the soft tissues of the neck and reflect their function. Here, we infer the presence, volume, and capacity of the cervical musculature of pterosaurs.

The Evolution of Body Shape and Locomotion in Archosauria [PDF]
, 2019 Locomotion is essential to the survival of all organisms. Extant animals display a broad range of adaptations to a wide range of locomotor behaviours. Locomotion can be observed directly in living animals, but this is not the case for fossil taxa which are known from only skeletal material.

Evidence for endothermic ancestors of crocodiles at the stem of archosaur evolution [PDF]
, 2004 Physiological and Biochemical Zoology 77(6):1051–1067. 2004. © 2004 by The University of Chicago.Physiological, anatomical, and developmental features of the crocodilian heart support the paleontological evidence that the ancestors of living crocodilians

Postparietal and prehatching ontogeny of the supraoccipital in Alligator mississippiensis (Archosauria, Crocodylia) [PDF]
Journal of Morphology, 2001 AbstractThe first record of the postparietal bone of Alligator mississippiensis, documented by transverse histological sections, is presented. It is the first evidence of the presence of this bone within Recent reptiles. The postparietal is present in a specimen with a head length of 32.3 mm.

Annotated bibliography of the subclass Archosauria (Class : Reptilia) : Jan 1960 - Dec 1984 [PDF]
, 2021 <p>The subclass Archosauria includes some of the most successful vertebrates to have evolved. Although traditionally viewed as 'cold-blooded' (= ectothermic) and therefore evolutionarily inferior to 'warm-blooded' (= endothermic) mammals and birds, data collected since the 1960s has resulted in significant re-evaluations and a complete ...
