I was running my character around in FO:NV near Novak and decided to use stealth to sneak up on a unsuspecting baddie encampment. I chose to climb high so I could get the drop on them when they were least expecting it. I was prepping on the top of the defunct tunnel entrance and happened to glance down and viewed a couple of odd figures embedded into the concrete. Reference pic for perusal.

Spoiler:

Has anyone seen these in their game?

I've seen it a few times in game before. Mostly when running an HD Texture pack - it's just where the two textures meet. Normally you wouldn't see that, but most textures, when put side to side, will have an effect like that.

I can't really explain it, but it's pretty normal and if you look hard enough, you'll see it on other places as well.

Huh, interesting. Kinda reminds me of the Rorschach test, like you see in the beginning of the game in Doc Mitchell's house. How odd.

Yeah, that's where a half texture is flipped/mirrored, as Ace already pointed out.

We're all thinking it...

Almost like a fossilized deathclaw XD

It's like those faces from the stones in GTA San Andreas. Guess it's just a bug.

ILLUMINATI of course its the only explanation

It might be that someone was literally nuked so far into the ground you could see the outline.

Looks like someone did a snow angel except that they did it in concrete instead of snow.

It looks a lot like a death claw. You guys see that.

It looks more like a grunt from Halo CE.

Looks like a reptilian,but it's prolly just a glitch,no biggie.
