#2845: Extinction Mechanisms explain
[A drawing of the Chicxulub meteor]
Marking to the right: ≈ 500 km3 (5 × 1014 L)
[Five arrows show individual small rocks coming from the meteor and spreading across the Earth. A sixth arrow provides more elaboration.]
Marking of the separate rock: 1 liter rocks
[The rock is shown entering a square marked “1 m2”, which has another arrow to a larger grid of squares, before an arrow back to the Earth.]
Marking near example square meter: >1 rock per m2
[Four dinosaurs are drawn, including a theropod, what may be a velociraptor, a sauropod, and a triceratops. Each has a small rock falling directly toward it.]
[List header, underlined:] Comet Extinction Mechanism Ideas
[The first three list items are crossed out]
Dust caused impact winter
Firestorms and ocean acidification
Triggered Deccan Traps magma
[The fourth suggestion is circled rather than struck through:]
The rocks hit the dinosaurs

Paleontologists are missing the obvious answer.
