Sometimes, strange and surprising things are buried in your own backyard! This is the Tualatin Mastodon.
It lives in the Tualatin Library, just south of Portland. You can read a little bit about it here.
In the 2013 wordless book Fossil, by Bill Thomson, a boy and his dog are taking a walk and discover that strange and surprising things are buried in their own backyard. When a stone the boy picks up breaks open to reveal a fossil from a prehistoric plant, the boy gathers as many stones as he can find and begins breaking them apart. What he finds is that each fossil carries with it a little magic too. The gorgeous and detailed illustrations are sure to trigger the readers’s imagination.
And the story you create, can change with each reading. A great book for lovers of fossils and dinosaurs.
