Praecambridium, a Common card
Praecambridium sigillum is an extinct organism that superficially resembles a segmented trilobite-like arthropod, and it was originally described as such, though the majority of experts now place it within the Proarticulata as a close relative of the much larger Yorgia.

The facts on the card
The card carries these facts from its Wikipedia article.
- It is from the Late Ediacaran deposit of Ediacara Hills, Australia, about 555 million years ago.
- On average, P. sigillum had at least 5 pairs of segments, with each unit becoming progressively larger as they approach the cephalon-like head.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Praecambridium article was read about 3,200 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 49 and blocks with 30: each hit it takes is cut by 12 %.
