Prehistoric Southern Colorado?

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.

There are various opportunities out there.  One great one, that I actually went to when I was in high school, is Crow Canyon Archaeological Center in Cortez, Colorado (crowcanyon.org).  Another great resource is the Archaeological Institute of America (archaeological.org); they maintain a list of all kinds of archaeological field opportunities from around the country and around the world.

I found one in Colorado. Just did a search on Yahoo. There must be more.

You have got to be kidding me. I have a favorite 'prehistoric water-dwelling animal'? I believe in a young earth anyway, so they're not prehistoric. I guess maybe Leviathan.

Yes, they migrate south, along the thermal currents rising from the highlands of New England, down to Hawk Mountain in Pennsylvania. They continue riding these thermals down the Appalachians to the southeast then west to Texas and into Mexico and Central America. They often migrate in large groups, spiraling up and down - it's an awesome sight!

I'd check river banks, lake shores, and road cuts in the coastal plain.  There was one place near Choke Canyon where the ground was literally covered with petrified wood...

Could be. Here's the Nature Conservancy's abstract on it; it's a common escapee in some areas of the country. I also included the Calphotos image link.

Colorado is great!  300+ days of sunshine a year. Clear blue skies. No high humidity, so nothing gets moldy, or mildewed, and cereal/chips don't get soggy.  There are very few bugs compared to other places. No earthquakes or hurricanes, and very few tornados. In most of the state it doesn't get too hot or too cold. Even when it is below zero, it is sunny and crisp and beautiful.  \n\nWater availability is a big issue - developers are supposed to be able to guarantee a 100 year water supply before building new houses (up to 300 yrs in some counties), and that totally gets blown off, so along the front range (eastern edge of mtns) even the deep wells will be dry in a few years, and there is going to be a big crisis.\n\nBut living here is wonderful... Black Canyon of the Gunnison; well maintained trails for skiing, biking, and hiking; native american ruins; Garden of the Gods; Red Rocks ampitheatre; dinosaur fossils; elk and big cats; opera houses and art and history museums; several pro sports teams; wineries and brew pubs; rustic mining towns; artist communities...  everything except the ocean!

Possibly the Clovis as you read on......\nStone-age people lived in the lands north of the Arctic Circle before the peak of the last Ice Age - much earlier than had been thought, suggests new findings.\n\nThe discovery of the site in eastern Siberia also hints that people might have moved from the Old World into the Americas at a much earlier date than believed.\n\nThe site along the Yanu River, carbon-dated as 30,000 years old, is twice the age of the oldest previously known Arctic settlement, report Vladimir Pitulko of the Institute for the History of Material Culture in Saint Petersburg, Russia, and colleagues.\n\nThe area is about 2000 kilometres from the Bering Strait. This is important as archaeologists have long suspected that some of the earliest Americans may have crossed the Bering land bridge from northeastern Asia. However, scientists had little evidence of Arctic settlements in Asia older than 14,000 years - the age of the earliest Alaskan sites. The age of the Yanu River site shows that people learned to live in the Arctic much earlier, and might have reached Alaska earlier than has been recognised.\n\n"Pitulko's find is exciting because it shows that people were living in an ecosystem that stretched continuously between Asia and North America. If they had wandered a little further eastward...bingo - they could have been the first Americans," Daniel Mann of the Institute of Arctic Biology at the University of Alaska in Fairbanks told New Scientist.\n\nReindeer bones\nRussian geologist Mikhail Dashtzeren found a rhino-horn foreshaft of a spear along the river in 1993. A foreshaft is the detachable piece between the main part of a spear and its point. Dashtzeren guided archaeologists to the site in 2001. Pitulko's team found 383 stone artefacts in the area, as well as many bones from ice-age Siberian animals including mammoths, reindeer, woolly rhino and bison.\n\nThe ancient site would have been an open meadow in the river's flood plain when occupied. It is unclear if people lived in the area all year, or only came north in summer to hunt. The abundance of reindeer bones indicates they were the most common food.\n\nThe flaked stone tools resemble those from more southerly sites at the time. However, the rhino-horn foreshaft, and two similar ones of mammoth ivory, resemble tools used by the Clovis people who spread over North America about 12,000 years ago and are believed to be among the continent's first human settlers.\n\nBut archaeologists are wary about linking the two. "It's a fabulous site," David Meltzer of Southern Methodist University in Dallas, told New Scientist. The dates look solid, and "it's tells us that people were in the far north a whole lot earlier than we ever thought."\n\nBut he cautions the new settlement and those of the Clovis are separated by 16,000 years and thousands of kilometres.\n\nJournal reference: Science (vol 303, p 52)

you can spend years here....zorathustrn granite,mica schists..various volcanics  in  canyons bottem  are  evidence trhat  an old mountain range...some say  as  high as  todays  rockies...[by base measurments]  was  eroded away  by  ice flows.....oceans came  and  left.....on  ariving  plant and  animal life  contribute  fossil remains and  calcite[the  making of limestone]mud stones and shales....the  various  banding  give us  ideas to the duration  andlife  of the times.....basically  the  areas  above the  river  are  sandstones  shales  and  mudstone....but there is  marble and dolomites....explore....thers  gotta  b   pics  on  net  somewhere

I'll bet that it's not prehistoric, but I guess it may be very old.  You'd have to have it appraised by a weapons expert and/or an anthropologist/museum curator/private collector of some sort.  Without knowing its age or where it was crafted, nobody can tell you.

Paleoanthropology.  Carbon dating and stuff like that.
