X‐ray microtomography and phylogenomics provide insights into the morphology and evolution of an enigmatic Mesozoic insect larva

Systematic Entomology, 2021
Fossils sometimes show unusual morphological features absent in living organisms, making it difficult to reconstruct both their affinity and their function. We describe here a new lacewing larva, Ankyloleon caudatus gen. et sp.n.

Evolutionary trends of the pharyngeal dentition in Cypriniformes (Actinopterygii: Ostariophysi). [PDF]

PLoS ONE, 2010
BACKGROUND: The fish order Cypriniformes is one of the most diverse ray-finned fish groups in the world with more than 3000 recognized species. Cypriniformes are characterized by a striking distribution of their dentition: namely the absence of oral ...

X-ray microtomography in biology [PDF]

Micron, 2012
Progress in high-resolution x-ray microtomography has provided us with a practical approach to determining three-dimensional (3D) structures of opaque samples at micrometer to submicrometer resolution. In this review, we give an introduction to hard x-ray microtomography and its application to the visualization of 3D structures of biological soft ...

Simulating permeability reduction by clay mineral nanopores in a tight sandstone by combining computer X-ray microtomography and focussed ion beam scanning electron microscopy imaging

, 2021
. Computer X-ray microtomography ( µ XCT) represents a powerful tool for investigating the physical properties of porous rocks. While calculated porosities determined by this method typically match experimental measurements, computed permeabilities are ...
