The Philadelphia International Airport is the 9th busiest airport in the world. The Philadelphia Marketplace Food, Shops and services at the airport have a mind-boggling number of eateries, retail stores that sell everything that one can think of, and a number of newsstands.
(See a gallery of plesiosaur and pliosaur pictures.) Plesiosaurs (Greek for almost lizards) were large, long-necked, four-flippered marine reptiles that paddled their way through the oceans, lakes, rivers and swamps of the Jurassic and Cretaceous periods.
There were different types of Plesiosaurs which were different from each other in size and in shape. The shortest were 2.5 metres long and the longest were 14 metres long! That is about as long as 8 adults lying in one long line! They all had long necks with small heads on the end.
