This is where a geological formation called the Karoo Supergroup is found. In this area, dinosaur tracks were found on a sandstone bed on a farm.

Secular geologists have notions about the layers of rocks forming by lava and sedimentary deposits over millions of years, but these do not make sense. One reason is that the critters could n
