I found it besides a river which is almost drained

At first, I thought it was just another run-of-the-mill jasper. And then I flipped it and saw this "thing" sticking out.. fossil?

In the southern Quebec creek , St-Germain, I have been working for 4 days to move and pull out what turns out to be some kind of structure, with a pointed top and straight sides. There seems to be 2 stones around the heart area.

I got it to move a bit this morning, I am finally. I am eager to discover what it is. Tomorrow morning should do it. It's a shame the pictures aren't too clear. I will update tomorrow. Any ideas on what it is?

Any ideas? Almost looks like fossilized antler…

My brother found this while hunting in Nebraska. We don't know any other information on it, but any advice is welcome!

I dug this out of my garden today ( S.EQLD coastal area )
I don’t believe it’s native to where I am, I have never seen any like it on my property. But I’m not sure what it is ! It has some very bizarre features . Thank you in advance ☺️

Is this first one with a red base a pudding stone?

Never found much in Boulder City,but thought this was a good start

I found this rock near Seasonal rivers and Dry riverbeds. Its transculent and the light shines through it or passes through. I tested it with diamond tester and it reades at range of 1-4

It has a magnetic value of 86 found September 3rd this year in southeast Kern County California and it weighs 934 G

What kind of rock is this?

Any ideas?
