“The original studies of the clay layer found at the K-T boundary assumed much or all of this layer was derived from fine impact dust,” he said. “More recent studies of this layer have shown ...

The conventional theory about K-T impact dust is that it obscured the sun, shut down photosynthesis, and snuffed out life. Kevin Pope from Geo Eco Arc Research shows in the February issue of ...

According to our resident palaeontologist, Paul Willis, Seymour Island is the best place in the world to actually see the KT Boundary, the day 65million years ago when the dinosaurs died. Skip to ...

Until now, paleontologists were unable to find any dinosaur fossils in the three meters below the KT boundary, which is the point where the meteor hit Earth.

Yale graduate student Stephen Chester discovered the last known dinosaur before the catastrophic meteor impact 65 million years ago.
