I saw extinct zoo's video on megaraptorids the other day and the part about their highly developed shoulders came in. Then I had a thought, what if they could throw stuff, like us. What if they could then hunt like us and soon idk how but gain higher intelligence. Like lets say they could throw develop to throw rocks, like could that be possible or like how would that go. Like spears are a were rudimentary technology,it's just sharp stick. I bet biting the end of a femur would work just fine. But in all reality its not that likely,tho it would be a cool spec evo project
