The fossilized remains of the triceratops specimen known as ‘Big John’ display injuries to the skull that may have occurred during combat with another triceratops, according to new research published in Scientific Reports.
Triceratops (Triceratops horridus) is a species of horned dinosaurs characterized by its large neck frill formed from extended patietal and squamosal skull bones. It has been suggested that this bony frill served as protection against injuries from other triceratops during fights.
