Re: Cold climate plesiosaurs (was Re: Survival)

(Dr. Paul Willis has asked me to send this to the list for him.)

Could you post this reply to the list for me?

I (Paul) have spent a lot of time looking at these sediments and never 
seen a dropstone. I also don't know of any records of dropstone 
in the inland sea. You could be talking about the Victorian deposits, 
but these are not part of the inland sea.

Isn't it interesting that people only started seeing Nessie as a plesiosaur
after plesiosaurs were known as fossils. Prior to that she was always 
drawn as a serpent. Seems to be a case of pattern fitting to a poorly 
observed object.

Yes, I'm getting Mary to post this because I'm currently off list (way too
busy) but I hope to be back soon. So a big hello to all on the list and I
hope you're not getting up to any mischief!
