Don't forget, animals (dinosaurs, but also insects) of this size needed the higher concentrations of oxygen in the atmosphere that was present, pre impact. Even a temporary disturbance in oxygen output of the huge forests and robust plant life (including algaes) would have killed animals of this size much quicker than starvation or temperature change.
- mark-r 9y agoThat's one thing I haven't read about yet, what happened to those oxygen levels of the distant past? Has anybody tried to estimate oxygen levels over time, especially during the extinction event?
