''"At last! At last! Huzzah! The plesiosaur is... complete! I never thought I would live to see this day! It's fantastic! Brilliant! A wonderful, joyful occasion! Delight ripples through my body and soul! But I'm getting carried away. Now then, where shall I begin with these leviathans? The great plesiosaurs... In actuality, plesiosaurs were not dinosaurs, but aquatic reptiles, which ruled the seas during the Mesozoic era. There were two main types of plesiosaurs, both of which had broad bodies, four large flippers, and short tails. The two groups were distinct in that one had long necks and small heads, the other short necks and large heads. The plesiosaurs ranged in size from 8 to 46 feet long, and their diets consisted of fish and other marine creatures. The first plesiosaur fossil was discovered in 1824, and subsequent findings have been made on every continent. Incredible, eh wot? Indeed! What I wouldn't do to dig one up myself! The thrill! Where in blazes is my shovel? Hoo hoo hoo! Oh, my! I must beg your pardon. The very idea of field work gets my crumpets toasting!"''

"The plesiosaurus appeared toward the end of the dinosaurs' days on earth. It was a reptile that lived in the ocean, and it's called "the long-necked dinosaur" in Japanese. Indeed, someone named Suzuki found the first one and named it that... But you see, he was still a high-school student when he discovered the fossils. He quickly became the neighborhood hero, wot!"
