Wyvern is made between the two. Since the sixteenth century, in English, Scottish, and Irish heraldry, the key difference has been that a wyvern has two legs, whereas a dragon has four. However, this distinction is not commonly observed in the heraldry of other European countries, where two-legged dragon-like creatures being called dragons is entirely acceptable. In the modern fantasy genre, there is little differentiation between dragons and wyverns, with two-legged, magical reptilian creatures all likely to be referred to as "dragons" without any differentiation between types. Wyverns, when present as creatures distinct from dragons, tend to appear as less magical
Wolves in heraldry Wolves in heraldry The wolf has been widely used in many forms in heraldry during the Middle Ages. Though commonly reviled as a livestock predator and man-eater, the wolf was also considered a noble and courageous animal, and frequently appeared on the Arms and crests of numerous noble families. It typically symbolised the rewards of perseverance in long sieges or hard industry. Wolves appeared frequently in English heraldry. A shield bearing two wolf heads was attributed to the Earl of Chester, circa 1070. "Two wolf's heads erased azure" were later used on the arms of subsequent Earls. Edward IV (1442–83)
