At first glance this is the Lamboidal suture. APpears a bit higher than normal, but don’t see what the big deal is. It appears on both side symmetrically.
We’ve become a forum with some really crazy ideas floating inside it.
I think you meant Lambdoidal.
Lots of people with very short hair have these marks. I don't know if they are scars or suture marks, or what.
My husband has very short hair; it never gets beyond the length you'd see in boot camp. When it hits the 3/8 inch mark, he's way overdue for a haircut. He has a faint mark sort of like this near his crown.
I see soldiers with the same lengths every day. Some of them have marks, folds, and what look like scars, too. I made a point of noticing the last time this came up here at FR.

Unless my hubby & who-knows-how-many members of the US military are in on the conspiracy, that's what it looks like, at least on this subject.
