It had a huge impact on the ocean and marine life also and changed them, wiping out species. The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep. Chicxulub Impact EventShocked and Unshocked Quartz at the Cretaceous-Tertiary (K-T) Boundary Quartz is a common mineral in the Earth’s continental crust. When an impacting asteroid and/or comet hits that crust, it produces enormously high shock pressures. Those shock pressures can generate shock lamellae or planar deformation features through quartz crystals. Along those planes, the crystal structure has been completely destroyed, producing a zone of glass. That type of damage is not ... Learn how a giant asteroid hit the Earth 66 million years ago and caused the Cretaceous-Paleogene extinction. See the rock cores from the Chicxulub crater that reveal the impact, tsunami, fire, and global cooling.
