For Equus Hunter, I'm really sorry for replying like a year later but here are some name suggestions for your pitch black carcharodontosaurus:

Shadowclaw

Nocturne

Midnight

Obsidian

Eclipse

Onyx

Raven

Phantom

Nightfall

Umbra

Darkwing

Void

Nightshade

Blackout

Grimshadow

Cinder

It probably won't help but I hope it did
