The story in short
Syngonosaurus was formally named in 1879 by H. G. Seeley.
Fossils referred to Syngonosaurus date to the Early Cretaceous (Albian), roughly 113.2 to 100.5 million years ago. Finds come from the United Kingdom, including the West Melbury Marly Chalk Formation. It was a herbivore and walked on two legs.
The fossils of Syngonosaurus 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 Iguanodontia, among the ornithopod dinosaurs.
