Marine Fossil Id Needed

[Shimmeron]

I found these fossils about a week ago next to Settlement Canyon Reservoir (Tooele County, Ut). I found them about 6600 feet up in elevation at about 1/5 mile away from the reservoir. The images are of the same rock but taken at different angles and sides, all except the last picture.

It looks like a coral to me, especially the first two pictures.  The last one I believe is a mineral stained rock, but someone else may have another idea for that.

Obliquely sectioned horn coral.

Axis of an Archimedes bryozoan ?

Geological non fossil.

We have rugosa coral in the Oquirrh Mountains, but they usually don't have elongated skinny bodies...thats what has me confused. The legnth actual continues onto the bottom of the rock too, although you can't see it in the pics.
