Sorry about the double posting....
To answer your question Adonis:
The Loch Ness Monster probably isn't a pleisiosaur, more likely one of the more common prosaic explanations for lake monsters...
-giant sturgeon: lake Eerie had a 28 foot 3 tonne sturgeon stirring monster reports
-giant eels: several lakes/lochs in Ireland, Norway, Sweden, Finland, Scotland have returned sonar readings which may well be freshwater eels in the 10 to 30 foot range
-giant salmon: some species of salmon can get into the tonne range
-giant catfish: some can get up over 300 lbs
-Cadborosaurus: not actually a dinosaur (despite the name) but an unclassified snake-like whale creature the only specimen of which was recovered from the belly of a sperm whale then photographed and discarded, sadly no samples were taken
-beaked whales: they do exist and are classified and recognised by science
-leopard seals: they look like sea serpents
A dinosaur is probably made even less probably by the fact that they flourished at a time when atmospheric oxygen levels were closer to 40% than the current 21%, which diminishes the possibility of their survival. Even the dinosaur (brontosaurus/apatosaurus) monsters rumoured to lurk in the swamps of Lake Tele (Republic of Congo) are more likely to be giant monitor lizard variants.
Hope that answers your question, sorry I missed it.
