Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

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

THE DETERMINNATION OF RESIDUAL STRESS OF GEAR TOOTH ROOT BASED ON X-RAY TECHNOLOGY
Transverse residual stress of tooth root has significant influence on bending fatigue strength of gears.But given the geometry of gears,using the method of exposing teeth root to complete determination of transverse residual stress at present,it not only

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

Method of calculation and test of dynamic tooth root strain for high-contact-ratio spur gears
ObjectiveAiming at the difference of load sharing and dynamic characteristics between high-contact-ratio spur gears and conventional spur gears, a method for calculating the dynamic tooth root strain was proposed considering the dynamic characteristics ...
