Ankylosaurinae is a subfamily of ankylosaurid dinosaurs, existing from the Early Cretaceous about 105 million years ago until the end of the Late Cretaceous, about 66 mya. Many genera are included in the clade, such as Ankylosaurus, Pinacosaurus, Euoplocephalus, and Saichania.

Features

Ankylosaurines are defined as being closer relatives to Ankylosaurus than to Shamosaurus.[2]

Diagnostic features of ankylosaurines include the nuchal shelf that obscures the occiput in dorsal view, and the quadrate condyle which is obscured lightly by the quadratojugal boss.[2]
