Re: Pterosaur embryo found in egg

[K and T Dykes <ktdykes@arcor.de>]

Hi Ben,

thanks for posting that one.  And thanks are also due to the mind-blowing
fossils from the Lower K of China.

<<The embryonic skeleton, which is exquisitely preserved in its egg, is
associated with eggshell fragments, wing membranes and skin imprints.>>

That seems to suggest at least one pterosaur laid eggs, the shells of which
could fragment; ie. an egg a with hard shell as known from crocs, non-birdy
dinos and birdies.  That sounds like a very archosaurian kind of thing to
do.

I don't know much about many things, and have heard there have been
differing opinions on the postulated relationships of dinos and pterosaurs.
Those are discussions I'll leave to people better qualified than myself.  I
certainly wouldn't want to suggest that a common habit of laying
hard-shelled eggs must be significant of something or other.  However, I
think 'interesting' is justified.

Is there no end to these beauties from Liaoning?  I hope not.
Cheers
Trevor
