Theosaurus 

The dinosaur god, or the lord of all the great lizards. A unique specimen, the skeleton of which has never been found, but the image of which appears in many of the earliest cave paintings, depicted as a giant bearded lizard seated on a cloud or floating in a celestial environment.

Early Brontosauri used to raise their heads and low to the sky in praise of the mighty Theosaurus.

Later Brontosauri built piles of rubble in homage to him.

So we assume...
