Utuntu dushimishije

Propanoplosaurus is known from a single fossil that is a natural mold and cast of a hatchling's skull and front body.1

It lived about 119 to 113 million years ago during the Early Cretaceous Period.4

This dinosaur is the first hatchling dinosaur ever reported from the eastern United States.1

The fossil was found in the Arundel Clay Member of the Patuxent Formation in Maryland.2

Propanoplosaurus belongs to the Nodosauridae family, a group of armoured dinosaurs without tail clubs.4

The fossil was collected in 1997 by Ray Stanford, who also named the dinosaur in 2011.2
