  Hylaeosaurus - Wikipedia, the free encyclopedia
Hylaeosaurus (hi-LAY-ee-oh-SORE-us), from the Greek words hylē/υλη "forest" and saurus/σαυρος "lizard", is the most obscure of the three animals used by Sir Richard Owen to first define the new group Dinosauria, in 1842.
Hylaeosaurus armatus was first named by Gideon Mantell in 1833, and is currently considered the only species in the genus.
Hylaeosaurus is traditionally considered to be a primitive nodosaurid, in the Polocanthinae subfamily, like Gastonia and Polocanthus.

 DinoWight EXTRA - Hylaeosaurus, an armoured dinosaur from Southern England
Hylaeosaurus was a armoured thyreophoran dinosaur, walking on all fours with rows of spikes along its back, to protect it from predators.
With Hylaeosaurus the coracoid is not co-ossified with the scapula, the proximal end of the tibia has a well expanded crescentic-shape.
The long axis of the distal articulation of the tibia is twisted about 50° relative to that of the proximal end the tibia is usually shorter than the femur (37% in the type specimen), in comparison to other nodosaurids.

 The Armoured Dinosaurs--The Nodosaurs
Hylaeosaurus was first discovered in the Tilgate Forest area of Sussex, England.
Another early Nodosaur was Polacanthus, whose name means "many spikes." Polacanthus was discovered in 1865 by the Rev. William Fox; it was a contemporary of Hylaeosaurus, meaning that it lived at the same time and in the same range.
The skeleton of Hylaeosaurus consists of the front part of the animal, and the skeleton of Polacanthus consists of the back part of the animal without any overlap between the bodies, leaving some paleontologists to believe that they may actually be the same species.

Hylaeosaurus, or 'forest-lizard', was the third dinosaur to be discovered and named (1833).
Initial belief that Hylaeosaurus and Polacanthus were the same genus and species occurred largely because the first Polacanthus specimen consisted only of the hindparts, and the first Hylaeosaurus discovered consisted only of the foreparts.
Due to this confusion, Hylaeosaurus has been thought of as being discovered on the Isle of Wight, when in fact the Isle of Wight remains were those of Polacanthus.

 BBC - h2g2 - Dinosaurs Of The Isle Of Wight: Ornithischians
Hylaeosaurus, or "forest-lizard", was the third dinosaur to be discovered, in 1833.
It was a for a long time considered to be the same genus as Polacanthus, but recent study has shown that Hylaeosaurus does not have a co-ossified scapukocoroid, and there are also differences in the shape of the tibia and the arrangement of armour.
Hylaeosaurus was smaller than Polacanthus, approximately 4 metres long, with probably a similar diet to Polacanthus.

 Concept of Nature Paper   (Site not responding. Last check: 2007-10-26)
When Megalosaurus, Iguanodon and Hylaeosaurus were first discovered and described, most prehistoric scenes, found as the frontspieces in books, primarily focused on marine reptiles and pterosaurs because their skeletons were more well known.
Hylaeosaurus looked the most lizard like of all three dinosaurs since its legs do sprawl a bit but they are still straighter than modern lizards.
Current depictions of Megalosaurus, Iguanodon and Hylaeosaurus are radically different from Owen's restorations (Plates 18, 19, and 20, respectively), which are now looked at as almost laughable in their inaccuracy.

 The geology of the south-east of England. : Mantell, (Gideon Algernon)
As the first armored dinosaur ever discovered, Hylaeosaurus not only established a third major family of prehistoric saurians but also provided indisputable evidence that it, at least, had been a land dweller, In 1824 and 1825 both Megalosaurus and Iguanodonhad been interpreted as primarily aquatic, like the modern crocodile.
Gideon's paper on Hylaeosaurus, withheld by him on Charles Lyell's advice, surfaced not in a learned journal but as one chapter [chap.

 The Dinosauria
Dinosaurs, one of the most successful groups of animals (in terms of longevity) that have ever lived, evolved into many diverse sizes and shapes, with many equally diverse modes of living.
The term "Dinosauria" was invented by Sir Richard Owen in 1842 to describe these "fearfully great reptiles," specifically Megalosaurus, Iguanodon, and Hylaeosaurus, the only three dinosaurs known at the time.
The creatures that we normally think of as dinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago) until the end of the Cretaceous (about 65 million years ago).
