The second 2 photos show ? petrified wood on the left side and quartz with a vein of ? malachite on the right side. CHEERS.....BOB

The piece is essentially a water-worn pebble of a homogenous rock mass without any joints or cleavage, yet it has 5 approximately evenly spaced sharp-edged indentations into it from different directions, giving it an apparent "animal shape" which is, I guess, what suggested to you that it might be a fossil?
However, it does not look like a natural shape to me, and my first impression was that someone has started to carve it into some sort of animal sculpture (a bear or turtle perhaps?), but maybe gave up because it was too tough!

The left-hand piece in the second photo might be a piece of massive quartz with roughly parallel fractures. Quartz does not cleave easily, but under the right kind of strain it can develop a system of fractures that looks like this. Of course it could be lots of other things, too . . . it's hard to tell from a couple of photos.
And which Crystal Lake area are they from? There are lots of Crystal Lakes around the English-speaking world.
