And all of those animals from different parts of the oceans died, coming to rest in a single layer. It’s been an incredible adventure decades in the planning. A multi-million-pound scientific expedition, weeks of drilling rock samples from deep inside a super crater, and months of studying hundreds of metres of rock samples. So, this was E. Yep. Which is million to . We were just jazzed about the science, all day long. Many people have been up for hours and they were still just going with enthusiasm, describing the cores, looking at the micro-fossils. It was a heady experience. All that hard work has paid off in a big way. The team has been able to reveal extraordinary new details, evidence about how the dinosaurs died. But perhaps even astonishing than what killed the dinosaurs… is what happened after they were gone. The asteroid and its aftermath ended the age of the dinosaurs. But as the cloud started to clear, months or years later, the dormant plants came back to life. And a tiny group of animals came out of hiding to inherit the Earth. Creatures that would, over millions of years, evolve into a huge range of different species… Including us. On the tip of my finger right here is a lower tooth of something called mesodma. This was a little guy who was probably about the size of a mouse. This is one tough little mammal. One of the very few species known to survive through the global devastation. It’s a blade-like tooth. It was able to feed on things like insects and seeds, so it didn’t have to rely on photosynthesis. Mammals had lived in the shadow of the dinosaurs for million years. But now it was their turn. This chance event that was the doom of the dinosaurs was a stroke of luck for the surviving mammals. With the dinosaurs gone, suddenly, the landscape was empty of competitors and ripe with possibilities. Just half a million years after the extinction of the dinosaurs, and landscapes around the globe had filled up with mammals of all shapes and sizes. Fast forward another million years or so, and they used to send their students down from Cornell. We met at the observatory in the control room. Husband and wife Duncan Lorimer and Maura McLaughlin share a passion for astronomy. Boys, it’s breakfast time! I was never, you know, the type of kid, when I was really young, that was super into astronomy. I still don’t know, like, a single constellation. But when I was sort of , , , I started reading science fiction. So when I went to college I decided to take astronomy classes. I still wasn’t sure what I wanted to do, but then I did research with a professor at Penn State that took me down to Arecibo and I observed pulsars. I was just so excited, and I just really enjoyed doing that and I thought, “OK, I think this is what I want to do”, and I’ve just stuck with it ever since. Nice day! Yeah. What do you have today? Gym. Gym. I got into astronomy in a different way to Maura, I guess. I’ve always been fascinated with the night sky. When I was about , taking my A-levels, my physics teacher saw that myself and a few other students were interested in astronomy and said,
