"The lambeosaurine supraoccipital has well-developed squamosal bosses and a short sutural surface with the exoccipital-opisthotic complex, and is similar to lambeosaurine supraoccipitals from the Dinosaur Park Formation in having anteriorly positioned squamosal bosses," the study's abstract reads.

Given that the squamosal bones of horned dinosaurs did not have much meat or other fleshy resources to offer, though, Hone and coauthors suggest that the bite marks represent scavenging when most of the rest of the young ceratopsid’s body was already picked over.

Compared to the stunning skeletons that have come from this place, the broken frill bone - part of a squamosal - might not look like very much.

It has especially prominent squamosal horns, an especially rugose-looking integument, and a neat, mottled pattern that involves black blotches on a greenish or yellowish ground colour.

The latter sends a horizontal or slightly ascending process backwards below the orbit to join the under surface of the zygomatic process of the squamosal, which is remarkably large, and instead of ending as usual behind the orbit, runs forwards to join the greatly developed post-orbital process of the frontal, and even forms part of the posterior and inferior boundary of the orbit, an arrangement not met with in other mammals.
