The story in short
The genus Cardiodon dates to 1841, the year R. Owen described it.
It lived in the Middle Jurassic (Bathonian), roughly 168.2 to 165.3 million years ago. Finds come from the United Kingdom, including the Forest Marble Formation. It was a herbivore. A habitual gait is not settled.
The fossils of Cardiodon 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 Eusauropoda, among the sauropod dinosaurs.
