Hi Therapod, thanks for replying!
No news is bad news, it's still a really cool rock. I'll find more fossils soon.
If this thing wasn't ever alive, it's even more weird to me.
About the 2nd rock, I'm pretty sure those are fossils in it. The camera blends the shadow with the flash, and I couldn't get a good enough pic without the flash. I need a better camera.
There are items lodged in the rock that have a round 3d shape.
When I first found it, I thought it was birdock, the velcro-type plant. After I found the "teeth" rock, I remembered the "birdock" rock and had a closer look and noticed a shell. Now I think that the "birdock" in the rock might be small round bristly sea animals. The shell might be a flattened indented bristly animal(it's shaped like a shell top down), a shell, or it all could be fossilized birdock. Etc
I edited the pictures and circled the embedded items.

The layer of rock that contains the "teeth" is different from the outside layers. The outside layers would be the "bread" if it were a sandwich. Those are made of 2 different types of rock. Both of those types of rock making up the bread of the sandwich are different from each other, and different from the layer in the middle that contains the teeth.
I'll need to get those items. This might take a couple of days to get the free time to carry out, if I have company. What's the purpose of finding out if it's Limestone?

Is the layers sandwiching the the "teeth" layer both the same type of rock?

Try this on the non-tooth layers. As a test you could try a 3 part water one part white vinegar etching. If you can form a masking "dike" with warm wax, and then allow to cool, so that only a small portion of the surface can be exposed to the acid you can find out if the stone is of a limestone composition. If the rock is limestone it will react with a fizz. When the fizzing stops clean off the wax damn/dike, wash the area with a baking soda water (1 part soda 5 parts water by volume acid neutralizer), allow to dry, and examine the etched area with as high power magnifier as you can. Report what you see, and the reaction to the acid solution. This weak solution should only clean the area and not erode the rock to any great extent. If the rock is non reactive we need to take another tack.
