Detlik: Not sure if contest is over or if this belongs here but most awesome thing in archaeology for me is
Megalodon . I really wanted to be an archaeologist after watching India Jones movies...but I realized I probably wouldnt find Holy Grail, shoot some Nazis and rescue hot chicks and meet aliens so I decided not to. And I blame meteors for killing such majestic creature as Megalodon. If I would win I would want Tropico Reloaded and I would want it to be gifted to mrmarioanonym.
swaimiac: Not being harsh, this is a commonly occurring theme in our field, I woud get asked about dinosaurs and other large prehistoric beasts a lot. I just wanted to point out the the Megalodon falls in the field of Paleontology. Archaeology is exclusive to human and proto-human remains... specifically the trash they left behind that might provide clues about how they lived. (simple explanation)
Someone above mentioned cloning Mammoths, that is a little closer to human prehistory, but unless the mammoth remains were found in relation to a human habitat an archaeologist would not be concerned about them.
However, it is entirely with in the realm of possibility that mammoth or megalodon skeletal remains/fossils could have been fashioned into tools by humans. I don't know of any actual finds, but in this case, the animal remains would be useful to archaeologists. (There is a subfield called Zooarchaeology which focuses on animal remains on human sites.)
Now, while archaeologists don't concern themselves with several million year old megalodon fossils, we do fight Nazis and rescue hot chicks on a regular basis. ;-)
Few years ago a friend of my father sent word to me; he had found some dinasour remains and wanted me to come and "dig them out." Explaining him why it was almost impossible he came upon some dinasour bones in his backyard and why it was a bad idea just to go and dig them out took some time.
Detlik: Whoah so the movies were true? How many cults did you destroy? :D
Didn't destroy any but helped understand cult of Apollo in in Western Anatolia.
