It's filled with charcoal and ferns. Not alot of organisms made it through the event so it was pretty quiet afterwards. The largest mammal was the size of a rat. Small dinos dominate afterwards? Good question. We think the smallest dinos were specialists and they were still pretty darn big - at least 5 to 10 kilos.

The extinction was geologically instantaneous but may have occurred over decades to centuries though many, many organisms died the day the asteroid hit. For the second question: watch the NOVA!!! Its all in there. Short answer, pretty fast in our estimation (100,000 years+).

The biggest surprise was the legume! We did not expect to find the world's oldest legume. Prior to this discovery the oldest legume was from southern Argentina.

The extinction was equally massive in the oceans. Different kill mechanism but still disastrous.

Yes. They are avian dinosaurs. Ponder that at dinner tonight. https://artsandculture.google.com/exhibit/the-dinosaur-on-your-dinner-table-denver-museum-of-nature-and-science/xwLigahP7vAcLA?hl=en
