The facts on the card
The card carries these facts from its Wikipedia article.
- The K–Pg boundary marks the end of the Cretaceous Period, the last period of the Mesozoic Era, and marks the beginning of the Paleogene Period, the first period of the Cenozoic Era.
- Its age is usually estimated at 66 million years, with radiometric dating yielding a more precise age of 66.043 ± 0.043 Ma.
- The K–Pg boundary is associated with the Cretaceous–Paleogene extinction event, a mass extinction which destroyed a majority of the world's Mesozoic species, including all dinosaurs except for some birds.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cretaceous–Paleogene boundary article was read about 90,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 68: each hit it takes is cut by 27 %.
