RE: Survival

So you're talking about a single species, surviving 65 million years (at
least) with a consistently small population.
I don't know what the minimum initial size for a gene pool has to be to
sustain a species for that long. But when you're talking about a small
population any way it becomes slightly irrelevant.

In order to facilitate modern sightings of 'Nessie' and her ilk, yet not
have any physical remains found you must have a very small population. I
think this one fact makes the answer to all your questions as "impossible".

        Many of you are more knowledgeable on dinosaur matters than me, but
I wish to submit a question or two for perusal:

1) What are the possibilities that certain dinosaur species survived into
"recent history" (i.e. last 2000 years) in isolated areas of the world?

2) What are the possibilities that aquatic reptiles, such as plesiosaur,
survived into "recent history" in the oceans/seas of the world?

3) What are the possibilities that aquatic reptiles survived into "recent
history" in inland lakes, such as Loch Ness?
