Scapula / femur bone central texas near dino vally in glen rose id please

[trap]

I found this very hard and heavy petrified fossil? off a hill in a ravine by a natural spring on our property after clearing some land. It has kind of a porous exterior. Perhaps part of the head of the bone broke off partially over time? scapula?  A rancher said it looks like a cow bone. It is so old and heavy I just don’t know if I buy that. Is it possible timing wise that it would be a fossilized cow or is it possibly prehistoric? Thank you for having a look. not sure of time period to look at.

Hey guys! reposting this with better description and High res pictures with a better camera and measurements. Found this near a natural spring on a hill cliff side in central Texas on the surface after clearing trees from land on the side of a hill kinda of cliff like and eroded. the specimen is hard and heavy, lots of porus holes(see pics) did the lick test and seems like more of a a fossil thank a rock but Im a newbie.  i did some recon on the geologic data base for rock type and time period in my area and added that in the images.  it tells a little bit about the geological makeup here. Im kinda on the border of two of them. any thoughts are much  appreciated and thank you all so much for your time.

It doesn't quite look like bone from 1000 miles away.

so you think its rock?

possibly cast of a lungfish burrow? or tree?

Chunk of limestone.

You’re in the “looks like a fossil shape” club at least! That’s seriously a small group of rock fossil identifications around here. 
 

Thanks for sharing!

This is not a bone.  There are s number of smaller marine fossils within your rock , so you do have fossils but the big piece is limestone not bone

One topic will work.  Just post additional images in a reply.

Yes, this very much looks like a chunk of weathered limestone.  I believe you can see molds/casts of invertebrate fossils in the areas that look broken.
