Tangvayosaurus facts talk about the fossils of the old species.

The nature of the Tangvayosaurus, including its appearance, possibly led to its name being assigned, which roughly translates to the 'Tang Vay lizard'. However, the information available on their specific appearance and mannerisms continues to be scarce.

For instance, there is no information regarding whether their teeth were sharp or if they were blunt enough owing to it being a herbivore. It is unknown how strong their teeth were.

Owing to its relation with sauropods, it is highly likely that a Tangvayosaurus was a creature of the Lower Cretaceous period that had a non-territorial nature. There were only two fossils, or rather specimens, of the Tang Vay lizard genus found by paleontologists in Laos.
