The facts on the card
The card carries these facts from its Wikipedia article.
- It is the most famous genus of the Osteostraci, an extinct class of Palaeozoic armoured jawless fish.
- The type species of the genus, C. lyelli was described from the Early Devonian-aged Old Red Sandstone of Scotland in 1835.
- However this species is poorly preserved, and numerous species have since been assigned to the genus based on characters that are common to many osteostracans, making it a wastebasket taxon.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cephalaspis article was read about 14,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 66 and blocks with 38: each hit it takes is cut by 15 %.
