ooouuuugghhh i could not stop thinking about the two headed calf poem in the context of a little baby t rex so i have done what i must.
while we have only found one fossil of a two-headed organism (a Hyphalosaurus) there is no doubt that there had to have been at least one two-headed dino born at some point (especially with how common polycephaly is in reptiles).
if you dont know the poem, it's "The Two-Headed Calf" by Laura Gilpin

Last time I drew a tyrannosaurus was like 4 months ago. This is unacceptable! So I drew some rexes!
And baby rexes! >:3

I present to you: The most detailed and complex artwork I've made in my entire life so far, just because I wanted to paint a realistic t.rex.

I know it's such a highly popular dinosaur but are they any interesting facts about the Tyrannosaurus Rex that isn't well known? I still love the Rexes wishing more dinosaur media treated it in the same way nature documentaries treat modern carnivores as animals just trying to surive and not just ripping up every living thing they encounter.
T. rex is actually one of the best studied (non-neornithine) dinosaurs ever, period. In fact, writing all the interesting facts we know about it is... more work than I particularly want to do right now, lol.
some things off the top of my head:
it wasn't built for moving fast in terms of miles per hour or whatever, but they were built for extreme cursoriality in other ways. Essentially, T. rex and its relatives were built for turning, quickly, on a dime. And they moved faster than the herbivores they were chasing. So these were animals built for short, surprise attacks on their prey. And ballet dancing
T. rex had the best sense of smell... ever. Like, ever ever. And its eyesight and hearing were good too. It had a fairly large brain for where it is in the dinosaur family tree, as well. Essentially, this was a dinosaur built to take in as much sensory info as possible, to pinpoint prey as quickly as possible.
T. rex aged kind of like people! IE, the process of going from infant -> sexually and skeletally mature adult takes about the same amount of time, with similar stages happening at similar times. So, T. rex had an awkward teenage phase! They were tall, but very skinny and lanky, and many researchers think that different ages of Tyrannosaurus filled different niches, with bigger rexes eating larger prey and the teens eating smaller faster dinosaurs.
That said, there's lots of evidence for familial groups and social life in Tyrannosaurs, based on fossilization patterns and footprint records. So it's very likely they took care of their young, and hunted in groups.
did they have feathers? no idea. they're big enough to have lost them for thermoregulation like many other dinosaurs did. they are in a group that have some big feathered animals, though, like Yutyrannus. Maybe babies had feathers and adults lost them. Maybe adults kept them some places and not others. We do know that there are parts of the Tyrannosaurus adult body that had scales. Beyond that - whether feathers were present too, or not - we don't know.
it was not skeletally sexually dimorphic. however, we do know that some tyrannosaurs were female because the fossilized when they were in the process of making eggs. during this process, dinosaurs - including living birds - deposit extra tissue in their bones called medullary bone. This tissue stores calcium to make eggshells from later. It's only present in actively ovulating female dinosaurs. So, we know some of our fossils were making eggs when they died!
the arms were small, yeah, but they were VERY strong. these weren't vestigial organs, yet, though their shortness was mainly due to the strengthening of the neck muscles. T. rex interacted with the world primarily with its head and jaws. The arms would have been helpful with holding on during mating, or possibly for display.
it wasn't a scavenger. it was an opportunist. No predators today avoid easy meals - life is all about minimizing energy spent to get more energy. But obligate scavengers tend to be flying organisms, ones that can cover huge distances, in order to find enough carrion. T. rex was definitely a predator, and had to hunt occasionally, but wouldn't turn up its nose at an easy meal.
T. rex lived all over western north america, right at the end of the age of dinosaurs. It was one of the most successful nonavian dinosaurs, ever, and would probably not have gone extinct so quickly if there hadn't been an asteroid.

Following in the footsteps of Prehistoric Planet is an upcoming documentary named T-Rex. Which plans to put the most recognizable yet misunderstood dinosaur in a spotlight that allows people to understand it for the animal it was and not the monster it is.
