Found this in austin texas near a creek I think it is fossilized bone fragment possably from larger reptile would be my guess if so. Any input would be helpful so maybe I can go back and look for more pieces if this is what it is or something worth looking into

I think it's another interesting piece of chert, Texas is full of it.

Hi,

 

What makes you think it’s a piece of fossilized bone from a great reptile? I don’t see any of that.

 

Don't take your fossils in the hand to make your photos, it accentuates the blur of moving and the hands aren't a good indication of measurement, there are all sizes !

In addition to the origin and age of the terrain in which the fossils are found, size is also important for proper identification. I invite you to read my last link in my signature. If you don’t have a rule, print the document I made available and put your fossils on it before making your photos, making sure to leave a box with the apparent size (pedagogical message)

The photos are not very sharp and somewhat blurred, but there's enough to see that this is just a rock of some sort.
