I.—Notes on British Dinosaurs. Part II: Polacanthus

Francis Baron Nopcsa

Next to Hypsilophodon it was Polacanthus which attracted my attention. A careful study soon showed that, after the death of the animal, the remains of some Crocodilian had accidentally become commingled with this Dinosaur. Besides this, some pieces, namely, the back part of a skull and a cervical, showed remarkably Iguanodon-like characters, and the same is also true of the pubic bone described by Seeley in 1892 as belonging to Polacanthus.

As I intend pointing out further on, and as has also already been done by Seeley, Polacanthus was constructed essentially after the Struthiosaurus plan, and this is the reason why this Iguanodon-like basi-occipital has to be removed from the Polacanthus remains.
