About Archaeopteryx and The Solhofen Lagoon

   I received this e-mail today.  Since I'm going out of town, I won't be
able to formulate an answer.  Since the e-mails he refers to came from this
list, maybe some brave souls could help him out.  It might be worth sending
the replies to the list as well.  If you want to see what was said
originally, the page URL is given in the message headers.

>3. One claims on the page, that only bottom waters of the lagoon were

>there. And then there would be no fossils of them.
>  But I can't understand how dead birds would have got in the bottom

>animals rise to the water surface. They would sink later, but then they 
>wouldn't be anymore very well-preserved. 
>  How do you explain this?
