Tyrannosaurus Rex: A Predator vs. Herbivore

Tyrannosaurus rex had the most highly developed sense of smell of 21 sampled non-avian dinosaur species. They would raise just one young age, teach them everything they knew about how to hunt and raise them from a young age up until they could hunt on their own. In a really weird way T-Rex was a much more nurturing parent than a lot of herbivores would have been at the time.
