Pareidolia or Mosasaur Bone?

[Zenmaster6]

Im in South Texas, Corpus Christi, which has no Cretaceous or even anything older than late pliocene material. 

 

However, architectural landscaping rock comes from the San Antonio Area due to its durability. I mostly check these beds for chert and flint to make arrowheads.

 

One day I found this nodule and I was very interested to know there were fossilized bivalves here from the cretaceous. 

 

After more scrounging around I found loads of petrified palm wood and eventually something that caught my eye as bone.

I found volcanic pumice I believe

I found weathered stones with pits from shells

Some water worn petrified wood.
