Cheilostome Bryozoa Anoteropora latirostris, a colonial marine invertebrate, constructs its skeleton from calcite and aragonite. This study presents firstly correlated multi-scale electron microscopy, micro-computed tomography, electron backscatter diffraction and NanoSIMS mapping. We show that all primary, coarse-grained platy calcitic lateral walls are covered by fine-grained fibrous aragonite. Vertical lateral walls separating autozooid chambers have aragonite only on their distal side. This… 

Bimineral Skeleton of Acoscinopleura crassa (Bryozoa, Cheilostomata) from the Maastrichtian of Germany Revealed Using X-ray Microtomography

The bimineral structure of the zooid walls of bryozoans Acoscinopleura crassa Koromyslova, Martha et Pakhnevich (order Cheilostomata) from the Maastrichtian of Germany has been revealed using X-ray

Investigating crystal orientation patterns of foraminiferal tests by electron backscatter diffraction analysis

Abstract. We studied the crystallographic orientation of calcite crystals in benthic foraminifers by electron backscatter diffraction (EBSD). Individuals of two species, Gyroidinoides soldanii and

Comparison of the Crystallographic Texture of the Recent, Fossil and Subfossil Shells of Bivalves

The crystallographic texture of modern, subfossil and fossils (Upper Pleistocene) shells of the bivalves Mytilus galloprovincialis, modern and subfossil Mytilus trossulus, as well as modern and

MicroCT as a Useful Tool for Analysing the 3D Structure of Lichens and Quantifying Internal Cephalodia in Lobaria pulmonaria

High-resolution X-ray computer tomography (microCT) is a well-established technique to analyse three-dimensional microstructures in 3D non-destructive imaging. The non-destructive three-dimensional

Pearl Sac Gene Expression Profiles Associated With Pearl Attributes in the Silver-Lip Pearl Oyster, Pinctada maxima

Pearls are highly prized biomineralized gemstones produced by molluscs. The appearance and mineralogy of cultured pearls can vary markedly, greatly affecting their commercial value. To begin to

Architecture of the flexible tail tube of bacteriophage SPP1

The atomic structure of the tail tube of phage SPP1 is presented and it is shown that the tailTube protein gp17.1 organizes into hexameric rings that are stacked by flexible linker domains and, thus, form a hollow flexible tube with a negatively charged lumen suitable for the transport of DNA.

Traumatic brain injury in mice induces changes in the expression of the XCL1/XCR1 and XCL1/ITGA9 axes

The in vitro experiments proved that primary murine microglial and astroglial cells expressed XCR1 and ITGA9, however they seemed not to be a main source of XCL1, which indicates that the XCL2 can be considered as one of the triggers of secondary injury.



Bimineralic bryozoan skeletons: a comparison of three modern genera

A combination of light microscopy, field-emission scanning electron microscopy (FE-SEM), electron microprobe, and Raman spectroscopic analysis is used here to study three cheilostome bryozoan taxa

Calcite and aragonite distributions in the skeletons of bimineralic bryozoans as revealed by Raman spectroscopy

Using Raman spectroscopy, it was possible for the first time to determine the mineralogy of small-scale structures, including orificial rims, condyles and hinge teeth, avicularian pivotal bars and rostra, and ascopore rims and sieve plates.

Evolving mineralogy of cheilostome bryozoans

Abstract Cheilostomes dominate bryozoan faunas today and are the only order of bryozoans to have evolved aragonitic, calcitic, and bimineralic skeletons. New XRD analyses of 177 recent species and 34

Architecture, Growth Dynamics and Biomineralization of Pulsed Sr-Labelled Katelysia rhytiphora (Mollusca, Bivalvia)

Abstract. We use pulsed Sr-labelling experiments to visualize growth of aragonitic Katelysia rhytiphora (Mollusca, Bivalvia) shells. The outer compound composite prismatic structure is organized into

Wall structure and mineralogy of the cheilostome bryozoan Metrarabdotos

The box-shaped zooecia of the two living and of five Tertiary species consist of: (1) a smooth primary skeleton including the basal, lateral, and distal walls, and the inner layer of the frontal

A survey of the carbonate mineralogy of cheilostome Bryozoa

The bulk skeletal carbonate composition of several Holocene species of cheilostome Bryozoa was determined by X-ray diffraction and differential straining techniques. Carbonate exoskeletons of the

The Secretion and Structure of the Skeleton of Living and Fossil Bryozoa

The mineral skeleton of the remaining stenolaemates represented by extinct trepostomes, cystoporates and cyclostomes, is exclusively double-layered and coelocystic.

Electron backscatter diffraction analysis shows a strong fibre texture with the [001] axes of aragonite aligned radially to the shell surface, which reduces anisotropy of the Young's modulus and adds to the optimized mechanical properties of bivalve shells.
