My guess is that it is a tumbled solitary coral which originally looked something like this one:
“A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber room of his library, where he can get it if he wants it.”
--Sherlock Holmes (Arthur Conan Doyle) in "The Sign of Four"
My totally uneducated unwarrented opinion : The lines in the first pic are in a pattern that I haven't seen in an acorn, acorns are fairly smooth? And the lines more cosmetic? I'm here to learn, thanks for posting this fossil, it's cute!

Good point, 'naturegirl' -- acorn lines are superficial only.
The more I look at this object, the more convinced I am that it is a stream-tumbled solitary coral. Perhaps it is from a stubby horn coral like Heliophyllum or Bethanyphyllum (both Silurian). Lots of Silurian fossils in Indiana and Ohio streams. Not so many in Illinois.

Thanks, nice to know what it is, and as the part you said it was tumbled...I found this over 45 years ago when I
was playing in some river rock gravel in a driveway.
I found mine 4 weeks ago on a beach in Northern Ontario. Very similar except it is not very round and has something stuck on the side of it. No idea what it is.
I know this is an old post but I wanted to add my photo in here since it looks like the same thing only with dark streaks in it, no history since it was purchased in a box of stuff from an estate sale.-
