That's what I was thinking too. Also, if it were smaller, it would have been the head of an atlatl dart, rather than an arrow. Bows and arrows were much more recent technology.
Did Clovis people have the atlatl?

I have doubts about that. It’s not rocket science.
All my kids made bows and arrows on their own before they started school.
