Shell Microstructure and Shell Architecture
(Springer, 2014)
Shell alterations in the limpet Bostrycapulus odites: A bioindicator of harbour pollution and mine residuals
(Elsevier Science, 2013-06)
Molluscs are commonly used as bioindicators because of their abundance, low motility and the information their shells record. Although in harbour areas gastropod shell deposition would be affected at an endocrinal level, ...

Microstructure and crystallographic-texture of giant barnacle (Austromegabalanus psittacus) shell
(2006)
Barnacle shell is a very complex and strong composite bioceramic composed of different structural units which consist of calcite 15 microcrystals of very uniform size. In the study reported herein, the microstructural ...
Shell damage in the Tehuelche scallop Aequipecten tehuelchus caused by Polydora rickettsi (Polychaeta: Spionidae) infestation
(Academic Press Inc Elsevier Science, 2013-08)
The different types of shell damage caused to the commercially valuable Tehuelche scallop (Aequipecten tehuelchus) by the polychaete Polydora rickettsi are described. X-rays, computerized tomography, shell sections, scanning ...

New petrographic and geochemical insights on diagenesis and palaeoenvironmental stress in Late Cretaceous inoceramid shells from the James Ross Basin, Antarctica
(Cambridge University Press, 2006-12)
New petrographic and geochemical insights from inoceramid bivalve shells of lower Campanian (Marambio Group, James Ross Basin, Antarctica) show that they suffered significant palaeoenvironmental stress just before their ...
Quantitative estimates of time-averaging in terebratulid brachiopod shell accumulations from a modern tropical shelf
(Paleontological Soc Inc, 2003-06-01)
Quantitative estimates of time-averaging in marine shell accumulations available to date are limited primarily to aragonitic mollusk shells. We assessed time-averaging in Holocene assemblages of calcitic brachiopod shells ...

Bone shell microstructure of Condorchelys antiqua Sterli,2008, a stem turtle from the Jurassic of PatagoniaMicrostructure de la carapace de Condorchelys antiqua Sterli, 2008, une tortue souche du Jurassique de Patagonie
(Elsevier France-editions Scientifiques Medicales Elsevier, 2016-01-17)
The histology of the turtle shell has proven to be a valuable source of characters for the study of development and shell origin, as well as early turtles’ lifestyles and systematics. Here we describe and discuss the shell ...
