Species
Polacanthus foxii
Polacanthus foxiiPolacanthus foxii roamed the subtropical floodplains of Early Cretaceous England, heavily protected by rows of sharp spines lining its shoulders and a fused bony shield across its hips. Unlike club-tailed ankylosaurids, this nodosaurid relied entirely on passive defense and low-slung stability to deter hunting theropods. It browsed tough, low-growing vegetation such as ferns, bennettitaleans, and cycads using small, leaf-shaped teeth.
