Need help

[Megasauras]

My friend found this in a landscaping rock bed at my job in Texas.

That doesn't mean that the rock is from Waco Texas but I mean that's where it was found.

Need help identifying what these three little things are in the rock.

Size of the items?

These do not look like crinoid stem imprints to me.

I think this is just weathering calcite on the limestone base.
I can't make out any actual fossils here.

 

Unfortunately, these may be too worn to identify confidently.

But I think they are geologic in origin.

I've seen cross sections of gastropods in rocks that look like this. It's only a vague possibility here though. I agree that crinoid seems unlikely.

How big is the rock?

the rock appears to have a crust, maybe just some impact points that removed some of it, just an idea 

[Megasauras]

It very well may be geolical in nature but three of them with them being the same size and shape and pattern?

And thus is on the side

maybe orthocone cephalopods ?

Cephalopod is likely. I think this is probably Cretaceous rock though. That would be too young for orthocones.

whitish clumps: severely micritized algae 

heavily dissolved ,perhaps juvenile rudist?

Rudist tend to be gregarious, which might explain the occurrence on this single slab/sample
