what most reasonable conclusion you could reach if you found a fossil of an alligator in northern Canada?

That you are in a Science Museum.

It could be both my personal opinion is that, if nessie exists, it is a plesiosaur, an aquatic animal that lived at the time of dinosaurs.  Impossible, you say? think again,many species that have been previously thought to be extinct have been found recently, like the coleocanth, a prehistoric fish.

While it might be possible that some of these creatures exist, it certainly can't be said to be 'probable'.\n\nWe are still finding new species of mammals and birds all the time.  Genetic studies have even shown us that some of the critters we thought we knew are more diverse than we thought.\n\nRecently it was discovered that the species we know as the African elephant is in fact two species, a savannah species and a forest species.  So we have 'found' one of the largest species of land mammal just in the last few years.  Another study found that there was a population of the Bactrian camel (the one with two humps) that was actually a separate species too.\n\nSo it is possible that there may be some critter hidden off in the deep forest somewhere that we've never seen before.  But the chances of something like Bigfoot/Sasquatch remaining undiscovered in the rather well explored forests of North America are rather low.\n\nThe best chance for new, exciting and incredible discoveries are in the seas.  We really have barely scratched the surface in our exploration there, and there could be all kinds of new, even huge and exciting finds down there.\n\nJust in the last few years, the Megasquid was described, whose body is larger than that of the Giant Squid (although the tentacles aren't as long), actual live footage of the Giant Squid was finally taken, and Coelacanths were found off the coast of Indonesia, 10 000 km from where it was thought was the only place they existed.

If it gets close enough, yes.  I don't think Alligators are very picky eaters.

Cool. I hope you found some good ammonites. You may have been in the Cretaceous Western Interior Seaway, which once connected what we now call the Gulf of Mexico to what is now the Arctic Ocean. The Pierre Shale is full of clams, ammonites, and baculites. \n\nThe Western Interior Paleontological Society has some good publications:\nhttp://www.wipsppc.com/#\nHere is link to a Pierre Shale field trip of the WIPS in Colorado:\nhttp://www.paleocurrents.com/baculite_mesa/index.html\n\nHere is an awesome website put together by Dr. Ron Blakey at NAU. For your interests, the first place to start would be paleogeography of the Southwestern US, which has paleogeographic maps of each major period (that include southern Colorado):\nhttp://jan.ucc.nau.edu/rcb7/paleogeogwus.html\nThe top page of his site is at:\nhttp://jan.ucc.nau.edu/rcb7/\n\nYou might also want to buy a copy of "Roadside Geology of Colorado". This series of books is written by geologists who are familiar with the state they write about and describe the geologic features that can be found along the major highways. Here's the cite:\nChronic, H. 1980. Roadside geology of Colorado. Mountain Press Publ. Co., Missoula, Montana, 334 p.\n\nThe Colorado Geological Survey sells a map for $7 that is titled "Colorado Geologic Highway Map" that shows lots of geology information, as well as a lot of other high quality geology related publications:\nhttp://dnr.state.co.us/geostore/ProductInfo.aspx?productid=MI-38\n\nHere is the USGS page for Colorado:\nhttp://www.usgs.gov/state/state.asp?State=CO\n\n\nEnjoy.

The polar bear is very well capable of killing an alligator given the proper environment so the polar bear would win.While alligators may kill larger prey by grabbing it and dragging it in the water to drown polar bears are too aggressive and strong to let alligators do this to them. \n\nAnyway if you want to have some fun about animal fights, check out this link:\nhttp://underscorebleach.net/jotsheet/2006/06/animal-fights?viarss

Researching crocodiles and alligators for a previous question I discovered American Alligators have been known to take down bears. The great white shark being larger and more powerful than an alligator should have no problem killing a bear. Of course great whites don't go that far north, but it's a hypothetical question.

most likely fish, or another animal that lives in water, perhaps an early reptile

"Dragon's World" by the dicovery channel was a great psuedo-Documentry on the finding of a dragon corpse in a glacier. This show has been release on DVD if you are intrested.

http://www.infothis.com/find/Hallucigenia/ (same as above, only with the source)\nHere's what it looks like:\nhttp://www.nmnh.si.edu/paleo/images/fhallu.gif\n\nHere are possible reconstructions:\nhttp://gsc.nrcan.gc.ca/paleochron/09_e.php\nhttp://evolution.berkeley.edu/evolibrary/article/0_0_0/cambrian_14\n\nI recommend you Stephen Jay Gould's book "Wonderful life" for a detailed and also entertaining account of Burgess Shale fossils.

There is no "The' prehistoric alligator. There were numerous species of prehistoric alligator just as there are several species alive today. \n\nWhich extinct alligator did you have on mind? If any old species will do then Diplocynodon ratelii is as good a name as any other.

If you're talking about the "tracks" in Paluxy river, Texas, these have been around, and been debunked, since the mid 1970's.  Even many creationist sources now recognize that the footprints are bogus.\n\nHowever, some creationist web sites and books *still* trot these out, decades after they've been debunked, as "evidence" of the co-existence of dinosaurs and humans, even though the overwhelming evidence is that they went extinct 65 *million* years before the first humans appeared.  \n\nIn other words, any source you see that brings up the Texas footprints is *not* the place you want to going for scientific information.

There are a number of things that might be looked for in core samples of glacial ice that has accumulated over hundreds of years. \n\nThe gases that are dissolved in ice hundreds or thousands of years old can be compared to the gases in today's atmosphere to draw inferences about greenhouse gases and climate. So you might have climatologists. Microbiologists might be looking for extinct microorganisms. Many arctic areas were once tropical or temperate (plate tectonics, continental drift, and all of that), so paleontologists could be looking for fossils of long-extinct tropical plants and animals in an icy terrain. Maybe even dinosaurs.\n \nA palynologist might be looking for pollen in the core samples of ice, or in strata of soil under the ice to confirm a range of dates to help establish timelines of fossils found in other locations.\n\nPersonally, I'm rooting for the palynologist!

Lynette Gillette, author of "The Search for Seismosaurus: The World's Longest Dinosaur," will speak on the new technologies used in the seven-year search to uncover the huge sauropod in a talk on Monday, Oct. 14, at 1:30 p.m. at the Peabody Museum of Natural History, 170 Whitney Ave. The talk is free with museum admission. \n\nMs. Gillette is curator of the Ruth Hall Museum of Paleontology at Ghost Ranch in Abiquia, New Mexico. She will touch upon her research on Coelophysis, one of the smallest and earliest dinosaurs ever discovered, which has been her focus for the past 11 years. While she is at the Peabody Museum, Ms. Gillette will be studying the museum's collections from Ghost Ranch containing Coelophysis fossils. Following her talk, Ms. Gillette will sign copies of "The Search for Seismosaurus," available in the Peabody Museum shop. \n\nLaw School alumnus to speak on telecommunications regulation
