Good Lord... Please do some reading on this first!
1. Plesiosaurs are NOT dinosaurs - in fact they are more distantly related
to dinosaurs than are living lizards and snakes. They belong to a quite
different reptilian line. Not every large reptile from the Mesozoic was a
dinosaur! NONE of the marine reptiles - mosasaurs, plesiosaurs, pliosaurs,
"geosaurs" (actually marine crocodiles), placodonts etc - are dinosaurs.
Neither are pterosaurs, though they are much more closely related to them
than the other animals I have mentioned.
2. There is no hard, unequivocal evidence for Nessie. The so-called
photographs are either outright frauds, heavily retouched or inconclusive -
IMHO there is no such animal, and it is remotely unlikely that it would be
a dinosaur if there were.
3. If by the "japanese fishing boat incident" you mean the so-called
"plesiosaur" carcass hauled up in the south Pacific, this was
unquestionably the rotting carcass of a basking shark. Basking Sharks are
well known to decay in such a way as to produce a remarkably
"plesiosaur"-like shape, and have been responsible for as number of "sea
4. If you want to tell your students about living dinosaurs, just ask them
to look out a window. It is almost universally accepted today, except by a
few diehards, that birds are direct descendants of small meat-eating
dinosaurs related to Velociraptor - or, to be more precise, birds are
dinosaurs, and therefore there are actually more species of dinosaurs
living today than there are species of living mammals!
