... of the mid-Polish basin. Low δ 18 O values of co-occurring ichthyosaur tooth enamel substantiate endothermy of these reptiles. An observed ontogenetic increase in the ichthyosaur enamel δ 18 O values (from ∼ 19.4 to ∼ 21.6‰ VSMOW) may be a result of long distance migrations although the effect of metabolic...

In this study, we tested predictions of the coevolutionary disequilibrium and mosaic-nutrient extinction models through the study of dental wear and enamel hypoplasia...

...T. Ben Amor; M. Kassem; W. Hajjaji; F. Jamoussi; M. Ben Amor; A. Hafiane Abstract Fluoride is an essential component in the mineralization of bones and in the formation of dental enamel. Excessive intake may result, however, in teeth mottling and dental and skeletal fluorosis. With an average...

...’. The height is 20.3 mm, and the shape is basically an elongated version of the ‘brown fang’. The ‘giant fang’ shows a gradual thinning of enamel – from apex to base – with a cessation about 38 per cent away from the apex. The crown below the enamel limit has a duller finish. The various postcranial skeletal...

... the opacity and the colour of the yellow paints. Opaque olive green colours are created by the combination of such yellow crystals with a bluish, Cu and Co bearing glassy matrix. The opaque red overglaze enamel is a mechanical mix of yellow Pb–Sb oxide crystals with an iron-rich (16 Fe 2 O 3 ) Pb–silica glass...
