Glossary

Spinosaurus aegyptiacus: One of the largest theropod chompy-bois to have ever lived, measuring between 12 and 18m when fully grown and weighing in at 21 tons by some (incredibly unreasonable) estimates. A minimum weight estimate of 7 tons means that this is still no joke of a dino. Although Spinosaurus lived during the late Cretaceous, it was s...

024 - Extinction Events (Saurolophus and Tiktaalik)

November 20, 2020 • 41 min

References

LIFE magazine from the 1950’s treats “racial senescence” like it’s a real thing that makes any sense

There’s a paper which tries to estimate which dinosaurs were alive at the time of the K-Pg extinction event. I don’t think it’s very good.

Of course, David is immediately shown to be wrong about dinosaurs possibly being on the way out when the space-rock hit.
