Ancient coral from walking my creek more than 20 years.....

So yea I've been picking this stuff up for decades and not until a few years ago did I find out what they were. I believed I had like slag or something. I believe that I have several different types here so if anyone knows what I have here please let me know. I can see the foliage on some of them. I've been trying to find out more about these with no success. A few years ago someone in a group told me what they were but didn't remember. At least at that point I knew they were coral. Let me know in the comments bellow what you think about these.

The big ones on the left look like some type of giant horn corals.

Heck yeah thanks for watching the video. I've been picking these things up for so long not knowing what they were. It does look like it got several different kinds there right?
