Review – Catastrophes and Lesser Calamities

Cover of Catastrophes and Other Lesser Calamities by Tony HallamCatastrophes and Lesser Calamities, Tony Hallam

Cheerful title, I know. It’s about mass extinctions, in theory: not just the really iconic one at the K-T boundary (that’s the dinosaurs), but the end-Permian, and others that have been defined as extinctions, some in more detail than others. I was hoping it would focus on the causes of mass extinctions and the immediate effects on animals, but actually it included a lot of geology and didn’t spend that much time discussing specific extinctions — more like ways we can find those extinctions in the fossil record, and even to what extent we can call these events mass extinctions. (For example, by the time you reach the K-T boundary in the record, most dinosaurs were already extinct and the diversity of species was tailing off.)

It’s a little dry, but not a bad guide; I only really skimmed parts of it, because I know a lot of this info about geology. It is interesting to see some things that people think they know being examined and the foundations weakened, though.
