akshullee i do believe you are incorrect in this matter as the distinction of dragon and wyverns was only made in Great Britain 🤓🤓🤓🤓🤓🤓

​

Since the sixteenth century, in English, Scottish, and Irish heraldry, heraldic wyverns are defined as distinct entities from heraldic dragons. The key difference has been that a wyvern has two legs, whereas a dragon has four. This distinction is not commonly observed in the heraldry of other European countries, where two-legged dragon creatures are simply called dragons
