Interesting Finds-Really Cool Fossils and Minerals!!!! Please Help :)

[autographcollector11]

I picked these up at a rock shop near my home a few months ago. I am going to guess that the light brown piece is petrified wood. As for the others-I don't have a clue.
Can someone help?


Thanks

I'm guessing ... Just below the toothbrush is hematite, then below that is mossy agate. White mineral could be selenite. How about travertine for the one in the upper right, and the giant guitar pick ... well ... maybe petrified wood.
