I think it may be a western painted turtle but im not sure. it has little red dots all along the oustide of its shell. it has a redish-orange bottom and is about the size of a dime.

It could be a Western painted turtle. A picture would be helpful. Can you post one? I have photos of baby turtles at http://www.fishpondinfo.com/turtles/babyphoto.htm that you can look at for comparison. Turtles with reddish bottom shells may be Western painteds or redbellied turtles. Where do you live? My page on caring for hatchling turtles is at http://www.fishpondinfo.com/turtles/hatchling.htm

I found it in columbia, SC and i'll get a picture as soon as i can.
