One of Sampson’s strengths is his ability to evoke the Mesozoic world. I was fascinated reading about how that world would have looked: No flowering plants (including grasses) until very late in the Cretaceous (the final era of the epoch); extreme seasonality in the first era – the Triassic – when all land was locked together in the supercontinent of Pangaea and plant life may not have been able to establish footholds much beyond riverine systems; balmier, less seasonal weather as the continents broke up and warm, shallow seas covered much of the land; there were no polar caps until late in the epoch; and there were no tropical rainforest-type environments, most biodiversity was found in the mid-latitude regions of the planet.
The ratio of production to maintenance between cold- and warm-blooded animals: Ectotherms (cold bloods) devote most of their energy to production; endotherms (warm bloods) to maintenance.
Even the largest predators of the Cretaceous were yapping puppies compared to herbivores like Apatosaurus (aka Brontosaurus). It’s likely a full grown Apatosaurus was effectively immune from predation (barring age or sickness making it vulnerable) so that T. rex focused on juveniles and smaller predators on eggs and babies.
