Thanks Lurker.
You know, I’ve been having this funny idea that perhaps bones, during fossilisation, mineral absorption probably causes the distortion of the sizes of the bones, to greatly exaggerated forms.
For example, those ancient dragon-fly fossils with metre-wide wingspans, don’t seem too practical to be able to fly on membranous wings, leave alone the chances that they might break like twigs, when flapped.
What do you think?
