Identify 2 points?

From north Miss. Is the large one a spear point? Guess the smaller was on an arrow? Thanks!

Nice! Is the one on the left a scottsbluff?

Wow that is a fat point, a bit unusual in my experience for a spear/knife to be that thick. Maybe a product of resharpening? The other maybe a dart point like an atlatl, seems just a touch large for a true arrowhead.
