Side Portiate- Speculative Tyrannosaurus rex

Tyrannosaurus rex is one of my favorite animals of mine, and I have always wanted to either write or draw down how I usually depict Tyrannosaurus rex. I never usually do full portrait colorations, although this has been a unique case.
A lot of the speculation for this reconstruction goes into what is scientifically plausible within reason for Tyrannosaurus. Everything from keratin to lips to display anatomy all has a rough basis and reasoning.

Lips-
Often a controversial topic to discuss, lips are something that is often restored on a variety of prehistoric creatures by me. Although I won't get into extreme detail, the reasons why I add it have a few things: Phylogenetics, beneficial support, and common sense. Phylogenetics is mainly used because of the fact that lips practically exist in every animal other than crocodilians, which themselves are derived from aquatic pseudosuchian's and aren't a good example to compare dinosaurs to, at least for lips. No reason to lose lips, and lips have more beneficial support for teeth/gums for something like Tyrannosaurus than without it. There's likely a variety of arguments already disproved, so move on.

Keratin-
Keratin is something that some people overlook. Here, the keratin that forms the two "horns" are mostly based off the keratin that would form in less derived Tyrannosaurids, such as Albertosaurus or Daspletosaurus. The horn feature, along with the keratin upon the snout can potentially be used as display and perhaps protection against intraspecific combat such as face biting. Keratin in some cases, although especially dinosaurs, aren't just their base. Psittacosaurus cheek spikes are extremely different from what the bone shows. Although while still speculative, keratin can still be added upon, rather than the traditional flat brows.

Neck-
The neck display feature is something roughly based off of old content that implies Tarbosaurus (=Tyrannosaurus?) bataar had a neck display "sack". Also while some call this not supportive enough, it is still entirely likely that the neck display feature can still exist, despite being from potentially supported speculation to mostly pure speculation in some cases. The display isn't intrusive in camouflage either, since it only takes up covered areas behind the jaw and under the neck.

The skeletal features used is mainly based of Sue, with some inspiration from Stan and Tufts-Love.

This is at least my take on Tyrannosaurus rex and reconstruction, at least from the things I can remember from the reasons why I reconstructed it the way I did. So hope you enjoy that read.
