Fossil fingers in river rock?

[relic lover]

Found this while collecting Flint from River Rocks in landscape. So it could have come from anywhere. Is this a fossil? Or just another one of Nature's tricks? The entire stone is about 2 inches long and somewhat Flint like.

One possibility is crinoid stalks. It was a stationary aquatic animal and the stalks preserved will so they turn up at tons of fossil sites. The other possibility is preserved worm burrows which sometimes filled with silicate minerals or formed flint in them over time.

Thanks sounds plausible I did find a couple pieces of coral amongst the rocks.

I once found a shark tooth in the river gravel around some shrubs. But that was in Texas.
