Description
At the time of writing, this represents a hypothetical one-size-fits-all integument that would be technically accurate for everything from Yutyrannus to Tyrannosaurus, but note that I would not consider this the most likely scenario for either. It is likely however that an animal intermediate between the two (such as the Appalachiosaurus pictured) would possess a transitional covering as shown.Additional note: the scales on the illustration have been exaggerated on the areas they are preserved to denote their presence. In reality, the reticulae are so tiny they'd be indescribable from this distance.

I get this from my own research...

With that of Yutyrannus is a Tyrannosaur/Proceratosaur

Plot twist: In the future, we find integument for T. rex that reveals who was "right" all along.
It wasn't Saurian. It wasn't Jurassic Park.
It was...Pokemon.
T. rex turns out to have been feathered the way Tyrantrum was, T. rexes are forever rendered with awesome neck ruffs and pseudo-beards but otherwise scaly/naked, everyone ends up happy, the end.
Just a thought
In all seriousness, great diagram! I think this fits pretty well with tyrant integument.

Really helpful, i have to say.
And i'm glad glad a "mane" for Tyrannosaurus rex is still on the plausible side

Thanks for the really helpful diagram, Tom. I'm glad to see that you put together the available data to make it pretty clear that the presence of scales on some parts of tyrannosaurids does not mean that they had completely lost all feathers as the paper seems to suggest.
One thing I'd really like to know more about is the position of the "integument from the neck". I read the Bell et al. 2017 paper as well as its supplementary info and could not find any further details about where exactly it was positioned. I noticed that you and others have placed it on the ventral surface of the neck. Is there another source for this? It makes the most sense given the data from Yutyrannus and Dilong, at least. I also wonder if the patch was indeed a lot further up (on the dorsal surface, for instance), if that perhaps just could be a taphonomic artifact...but if it was indeed on the dorsal surface, that would have restricted the feather distribution of Tyrannosaurus quite a bit further.
I'd definitely like to know your thoughts about that, as my mind has been puzzling over it since reading the paper.

The paper does not at any point state where the impression from the neck comes from, unfortuntely. Hence why I have included a question mark on the graphic. My tentitive placement of it on the ventral comes from the line from the paper "...if partly feathered, these were limited to the dorsum" which implies that the scale impressions are all ventral, but as it doesn't state it outright, we cannot be certain at this time.

Excellent composition to illustrate this crazy controversy that had developed by misinformation. Fantastic work!!!

Nice to see it all summed up in one animal. This is very practical!

Very nice, and certainly reasonable

Good job. Also, does this mean Saurian has to shave Rexy's butt or modify it in any other way?

For the dorsal coat, do you think the body could gradually turn from the abdominal and "pelvic" scales to smooth skin towards the back? If not, and the upper body was necessarily fully scaled, a more sparse feathering between the scales could be the maximum to derived tyrants after all.
Also, excellent work compiling all this data into a picture/guide! Super valid contribution!

We don't have evidence either way, but I suspect it is most likely feathers and scales would gradually grade into each other.

Very awesome reference. Seems very plausible.
