 The Utah geologic map describes the location/formation as Manning Canyon Shale (lower Pennsylvanian and upper Mississippian)  with black to brown shale with numerous thin beds of light-brown-weathering, gray, fine- grained, shaly sandstone, some lenses or beds of rusty-weathering grit, and one or more thick beds of gray to black, cherty limestone; at least in west contains some beds of light-brown quartzite; shale is carbonaceous with occasional nodules of marcasite.

 

The area I was exploring the most was this type of rock - thick beds of gray to black, cherty limestone -  as described above.  There were several outcrops of limestone ridges along the rolling hills on the west side of Utah Lake. 

 

The area is BLM land with a sign at the gate reminding visitors that Shooting is Not allowed because of the ancient petroglyphs and risk of wildfires.  Also, no collecting on this location. 

 

So I took only photos and left only footprints on this excursion. 

 

Here's the images of what I saw.

 

Standing on an outcrop of limestone with Mt. Timpanogos in the left background, 11,752' summit. This elevation is around 4700' ASL.

And just below the lizard's head is a fossil that I think might be bryozoa. There are also at least 3 lichen species mixed among the fossil. Brown bulbous, gray and orange ones. Zoom in to see the fossil best.

Thanks for any responses.

The first item reminds me of a brachiopod valve (derbyia?).

I agree with bryozoan for the other. I love that picture, also!
