The story in short
In 1899, F. Ameghino published the name Clasmodosaurus. The name means “fragment-tooth lizard.”
It lived in the Late Cretaceous, within an age that is only broadly constrained. Finds come from Argentina. It was a herbivore and walked on four legs.
The fossils of Clasmodosaurus are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Sauropoda, among the sauropod dinosaurs.
