K-T Extinction
We can’t imagine what it must have been like to be a dinosaur with a 112 mile-wide asteroid barreling towards earth. This sounds terribly frightening to the absolute, utmost jurassic level (as it should—it was responsible for eliminating approximately 80 percent of all Mesozoic species). However, the bright side? These K-T Extinction Fort Knocks look fantastic and pay homage to an awesome, larger-than-life species!
