Multitude of Images Including a Possible Mammoth or Mastodon

I'm often at a loss to know what title to use for my postings because so often, a wide range of images are featured in one stone. For instance, this one seems to include birds, reptiles, lions, muskox/buffalo and humans. I wonder if the photos 3-5 are images of a mammoth or mastodon?

Recently, I found this online map of Southwestern Ontario which pinpoints the locations where mammoth and mastodon remains have been located. Many are within an hour's car ride of our farm; judging by the map, it has been mostly mastodon remains which have been found in our area, but it is my understanding that both were in the Great Lakes region.
