The asteroid that killed the dinosaurs struck the Chicxulub crater, located on the Yucatán Peninsula in Mexico, and the impact site is now buried under the Gulf of Mexico with its evidence preserved in the surrounding crater ring.[3][5]
- The Chicxulub crater is about 180 kilometers (110 miles) in diameter and sits beneath the seabed off the Yucatán coast. This structure is the widely supported impact site linked to the mass extinction at the end of the Cretaceous period.[5][7]
- Evidence from core samples and tsunami deposits near the crater has helped scientists reconstruct the events of that day, including the globally significant climatic effects that followed the impact rather than a direct kill-by-blow scenario.[1][4]
- Ongoing research continues to refine where the debris from the impact landed and how it dispersed, with Tanis-type sites in North America offering snapshots of the immediate aftermath, but the primary landing site remains the Chicxulub crater itself.[2][4]

If you’d like, I can pull up the most recent summaries from major scientific outlets or provide a concise timeline of the events from impact to global climate effects.
