The Bible and Pterosaurs
There is an increasing amount of archaeological and linguistic evidence that pterosaurs (flying reptiles) were mentioned by several authors of Scripture. This introductory article will deal with some of those biblical words and what I've learned about them from word studies and archaeology. The scientific basis for this study has been established by articles for peer-reviewed scientific publica...
متن کاملThe Origin of Pterosaurs
In 1914, Freiherr Friedrich von HUENE restudied the five nearly complete skeletons and miscellany of Scleromochlus taylori (Fig. 1), a small archosaur from the Elgin Sandstone (Upper Triassic: Norian?) of Lossiemouth, Scotland (WOODWARD 1907) . The tiny skeletons are preserved only as impressions in a coarse sandstone matrix; yet HUENE, using "strongly one-sided, artistic illumination, identifi...
متن کاملConstraints on the wing morphology of pterosaurs.
Animals that fly must be able to do so over a huge range of aerodynamic conditions, determined by weather, wind speed and the nature of their environment. No single parameter can be used to determine-let alone measure-optimum flight performance as it relates to wing shape. Reconstructing the wings of the extinct pterosaurs has therefore proved especially problematic: these Mesozoic flying repti...

متن کاملSailing the skies: the improbable aeronautical success of the pterosaurs.
Pterosaur wings bore a striking resemblance to sails, having a bony spar at the leading edge, formed by the forelimb and one enormously elongated digit, and an elastic wing membrane. Such simple wings would be expected to have performed badly due to excessive deformation, membrane flutter and poor control characteristics. Here I discuss how certain anatomical features, specifically a forewing m...
