(1) Dr William Atherstone and Andrew Geddes Bain discovered the first cretaceous stegosaur in the Bushman's River Valley.(2) A mathematical analysis of a fossil stegosaur 's bones leaves little doubt that the creature's spike-studded tail was an effective defense against predators.(3) They snaked with the contours, curling and buckling, even twisting vertically in places and splaying like the back plates of a stegosaur .(4) The small stegosaur Kentrosaurus closely resembles primitive European and Chinese forms, but is quite unlike the large and advanced American Stegosaurus.(5) However, this would not be as effective in stegosaurs that had smaller plates, some plates and some spikes, or all spikes.(6) Originally thought to have been a form of armour-plating, the plates of advanced stegosaurs were, as can be seen here, actually quite thin and full of holes for the accommodation of blood vessels.(7) A new study of the finlike plates that lined the backs of the Jurassic-period plant-eaters known as stegosaurs suggests that the plates served a rather simple purpose: dinosaur I.D.(8) Although, as for stegosaurs , we have no independent evidence of mate competition, we can use the features of their plates to identify species.(9) He's warm-blooded, or at least warm-bodied, has the wings of a bat, the tail of a stegosaurs, the spikes of a relative of a stegosaurus , the sail of a spinosaurus, and the shield of a triceratops.(10) Birds are highly dimorphic sexually, and imprinting is important; however, stegosaurs (like other dinosaurs) do not appear to be highly dimorphic sexually, and the role of imprinting in dinosaurs cannot be assessed.(11) Other herbivorous dinosaurs of the Jurassic included the plated stegosaurs .(12) Museum visitors eager to walk with the dinosaurs can also see stegosaurus , which brandishes a long swinging tail studded with sharp spikes but has a brain the size of a walnut.(13) The neighbouring Museum of Natural History has the third-largest dinosaur collection in the world, including skeletons of tyrannosaurus rex, diplodocus and stegosaurus .(14) Other dinosaurs lacked them, and the forms of plates and spikes vary among stegosaurs without respect to body size.(15) The thyreophorans are the armored ornithischians: the stegosaurs and ankylosaurs.(16) Such canals are often ringed internally by lamellar bone, as in stegosaurs .
