Odd garden geos

[sonny61]

I found these odd fossils today while working in my garden. My property is 1004 ft. above sea level. Man, the water must have really been deep to grow these tubers (?). At least that is what I think they are. Rocks around here have many animal skeletons embedded in them. I found one with a complete bird skeleton in it. Any ideas appreciated. Thanks Sonny

It's coral. Just because you live at 1004 ft above sea level now doesn't mean its always been that way

The first image appears to be fossilized invertebrate burrows - an ichnofossil. The second is definitely a branching colonial coral.
