3.5" Ankylosaur (Polacanthus) Caudal Vertebra - Isle of Wight, England

This is a 3.5" wide Ankylosaur (Polacanthus sp.) caudal vertebra from the Isle of Wight in England. Aside from remnants of the vertebral foramen, everything superior to the centrum has weathered away, along with weathering of the cortical bone along the edges of the vertebra. There is minimal repair and restoration on this vertebra. Any British dinosaur material is pretty hard to find on the market and this is a beautiful piece.

Polacanthus, while still an Ankylosaur, is more than likely a Nodosaur, based on the lack of a tail club and other various biological factors. However, this phylogenetic placement is still heavily debated.

It comes with an acrylic display stand.

Ankylosaurs were herbivorous dinosaurs that lived during the Cretaceous (65-68 million years ago). As the evolution of Ankylosaurus progressed, they developed bony armor that covered their bodies in the form of plates, scutes and spikes, with some even developing armor on their eyelids. While their armor and bone-shattering tail club are thought to have been used for defensive purposes against predators such as Tyrannosaurus, it's possible that some of the armor on their head may have been used for display. Adult Ankylosaurs are believed to have reached up to 25 feet in length and weigh 3.3 tons!
