The x-ray diffraction patterns of the denticle material from several species show that the material consists of the mineral goethite. This is the first indication that goethite is precipitated by marine invertebrates. The mineralogy of the denticle caps has biologic and geologic implications. 
Lepidocrocite, an Apatite Mineral, and Magnetite in Teeth of Chitons (Polyplacophora)
X-ray diffraction patterns show that the mature denticles of three extant chiton species are composed of the mineral lepidocrocite and an apatite mineral, probably francolite, in addition toExpand
Biologic Precipitation of Fluorite
TLDR
The occurrence of fluorite in mysid statoliths confirms the earlier interpretations based on insufficient documentation, andfixation of fluorine in hard tissues of marine invertebrates is extensive in the shelf seawaters and minor in the bathyal zone of the oceans. Expand
Weddellite in a Marine Gastropod and in Antarctic Sediments
The calcium oxalate dihydrate mineral, weddellite, has been identified in a microarchitectural component of the gizzard plates from the deepwater gastropod Scaphander cylindrellus. This is the firstExpand
Opal Precipitation by Marine Gastropods (Mollusca)
TLDR
The high silicon content of certain radular sites of the Patellacea (Mollusca, Gastropoda) is shown by infrared absorption spectrums to be fixed in the form of the mineral opal, indicating the role of this previously neglected taxon in biological fixation of silica in the oceans. Expand
Minerals of the Radular Apparatus of Falcidens sp. (Caudofoveata) and the Evolutionary Implications for the Phylum Mollusca.
TLDR
The discovery of amorphous iron oxide and hydroxyapatite in the highly modified radular apparatus of Falcidens sp. Expand
Silica Biomineralization in the Radula of a Limpet Notoacmea schrenckii (Gastropoda: Acmaeidae)
TLDR
Electron-dense granules in a nanometer size range were observed in ultrathin sections of tooth specimens in early mineral-deposition stage; electron diffraction analysis indicated that silica is the primary component of these granules. Expand
Borings As Trace Fossils, and the Processes of Marine Bioerosion
Marine borers are nearly ubiquitous in the modern seabed. Their distinctive excavations provide abundant potential trace fossils, and their general erosional activities (bioerosion) are importantExpand
Mössbauer Spectroscopic Study on Iron-Containing Biominerals in the Limpet Radula
Mossbauer measurements on iron-containing biominerals in the limpet radula have been carried out in the temperature range 5–420 K. Spectra show the same parameters and behavior as seen in goethite.Expand
Mineralisation in the teeth of the gastropod mollusc Nerita atramentosa
TLDR
The teeth of the Nerita atramentosa are tanned, and additionally hardened by the possession of biomineralised granules which contain sulfur, chlorine and calcium, together with a large range of other elements including silicon, aluminium, titanium, chromium, iron, nickel, and manganese. Expand
Morphology of Goethite Crystals in Developing Limpet Teeth: Assessing Biological Control over Mineral Formation†
The continuously forming mineralized teeth of some mollusks can be conveniently studied during their formation. The mature teeth of limpets (Gastropoda) are composed of goethite (α-FeOOH) crystalsExpand

The Role of Iron and Silica in the Structure of the Radular Teeth of Certain Marine Molluscs
The radular teeth of the Patellidae consist largely of silica and iron. The teeth of the Chitonidae contain large amounts of iron and little or no silica. The teeth of Dentalium contain small amountsExpand
SIZE DISTRIBUTION, EROSIVE ACTIVITIES, AND GROSS METABOLIC EFFICIENCY OF THE MARINE INTERTIDAL SNAILS, LITTORINA PLANAXIS AND L. SCUTULATA ,
TLDR
It is concluded that environmental factors cause the observed size distributions, and the amount of wave action at a given locale appears to be one of the influencing factors. Expand
