In fact, the owl hybrid shown is a "sparred owl", i.e. a cross between spotted and barred owls. Thus, these are not different genera, but closely related species of the same genus.
Would have loved to ask more about the ecology of its environment. Why is it that T. rex is one of the most common predators in their environments and why we don’t see many different medium to small carnivores where T. rex is present. Were they that specialized and successful that they outcompeted most other predators due to how their specializations throughout their lives? In the Jurassic you could have several different large carnivore species in the same environment with several medium sized and plenty of small carnivores filling other niches.
I actually think I can help you out with that. If you want to know Thomas Holtz’s thoughts on that, search “Teen Tyrants In A Gig Ecology” and Thomas Holtz and a whole lecture about exactly what you are asking about is online. Great talk. Enjoy.
Always thought it was more helpful to perceive speciation as a fluid and ongoing process instead of a necessarily fixed state. Terrific lecture. This actually comes up in the reptile hobby often enough as there is a bit of a rift between the pro and anti hybridization crowds. I'm totally pro-hybridization. Heck, we are "hybrids".
The "3 species of tyrant" bit really gets at something. People want to name things - make their mark, so to speak. Given that we live on average 80 years, trying to define an animal that, in some form, existed for 25 thousand times that long (assuming T-rex lasted 2 million years)........obviously there's going to be some change there. I know that cladistics is the "best fit" solution we have for understanding what we discover, and that's very useful for describing things. I wish more researchers and scientists would point out that every little thing we get is just a snapshot, with millions of years before and after missing. People can't even agree on speciation with extant animals, within their own lifetime. Maybe we need a different framework for extinct animals? It just seems somewhat broken. Why are we expending brain-power trying to differentiate slow species progression.....instead of evaluating, over time, with the snapshots we get, what was successful, what failed, what lasted, what didn't? I guess I know the answer: You don't get to name anything if you do research like that. Still, I'd love to see it.
So the three species of T-Rex are the tyrant lizard King, Queen, and Emperor, damn these things just can't help but be badass. Even with the dorkiest, nerdiest clade of humans using a dead language can't make this thing uncool!
Is there a correlation between femur size and cursoriality in mega-theropods? Orrrrr is the hypothesis based solely on the arctometatarsalian condition?
Femur size increases close to body size, so it is the least informative part of this. However, the proportionately long tibia length, and much more so the proportionately long metatarsus, the proportionately slender nature of the of the metatarsus, the arctometatarsalian condition, and the proportionately expanded size of the ilium all point to tyrannosaurids (and independently, ornithomimids and alvarezsaurids, and to a lesser degree troodontids and caenagnathids) being more cursorial than other theropods of their respective body sizes.

Tyrannosaurus changed a lot in its morphology as it grew, and likely filled the mid-sized theropod niche as juveniles
