The story in short
In 1888, O. C. Marsh published the name Pleurocoelus.
Fossils referred to Pleurocoelus date to the Early Cretaceous (Albian), roughly 113.2 to 100.5 million years ago. Finds come from the United States, including the Arundel Formation. It was a herbivore and walked on four legs.
The fossils of Pleurocoelus 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 Macronaria, among the sauropod dinosaurs.
