Reptilian humanoids

often referred to as reptilians or lizard people. These beings are typically depicted as humanoid creatures with reptilian features, such as scales, slit-like eyes, and sharp claws. In folklore and fiction, they are often portrayed as ancient, intelligent, and sometimes malevolent beings, capable of shape-shifting and possessing advanced technology or mystical powers.

The vikings worshiped a reptile and adorned "horns" on their helmets.

Which were actually the snake's two "spikes" on it's head. There are also tales

that "Lindormen" may have existed in the forests before the ice age. 

Scientists do not believe that there been large snakes in Europe. Despite evidence in the culture and religion of the Scandinavians centered around a large reptile and also their rune-stones.
