I just finished five months of generals, and during that time my artistic output has been next to nothing (evidently). Having taken such a long drawing hiatus, it'll be tough getting back into it. But that's not what this journal entry is about. I mentioned that introductory point because I have an interesting concept I've wanted to draw for some time but could never muster the mental energy to draw it, because college fries the brain like that. That concept is this entry's namesake.

Crested tyrannosaurs aren't speculation, obviously. Guanlong is the most prominent example, although other proceratosaurids were potentially crested as well. Even the structure adorning the skull of Yutyrannus can be interpreted as a crest. Most of these are all smaller and more basal tyrannosaurs, obviously. The crests are thus presumably basal characteristics as well, lost in the more derived tyrannosaurids. Or were they? I couldn't help but notice that many tyrannosaurids have rather scabrous snouts. That is, they're not smooth; as though they anchored something in life that has evaded preservation. This observation has previously been the method to my madness in reconstructing my tyrannosaurs with chicken-like combs and other such fleshy structures. However, is it feasible that as tyrannosaurs grew larger and more derived, their bony and presumably keratin-sheathed crests were reduced to scabrous anchors for lighter-weight keratinous crests (the sheaths and crests being homologous)? Presumably for sexual display, these structures might have looked similar to the crests of Guanlong or Yutyrannus, although they could have potentially adopted entirely unique designs as well.

One of my friends took the liberty of drawing this concept, giving Tyrannosaurus a Yutyrannus-like crest: dj-miller.deviantart.com/art/C…. If anybody else is interested in illustrating this concept, be my guest.

I've seen subtler bumpy regions over the eyes and nose on quite a few drawn Tyrannosaurus, but a huge keratin/cartilage crest would also be a great addition.

What I'm curious about is crested rapters. I created a fictional rapter species that has a Yutyrannus-like crest and I'm wondering if it is a realistic idea?

Usually the bones of an animal adorned with a keratinous appendage will have some indication of that appendage's presence. In tyrannosaurids, the giveaway for me was their scabrous snouts. Dromaeosaurs have no indication of their snouts supporting such structures, and they're small enough to where keratin wouldn't necessarily need to replace bone, so if they did have solid crests, they'd have the bones to show it. Alas, they don't. However, dromaeosaurs could have easily been adorned with fleshy or feathery head ornaments. E.g. Anchiornis had a crest of feathers on its head, so I can easily imagine a fictional species having something similar.

Well originally they had a large crest of feathers but I decided because of their name (Lophorapter) that they needed a bony crest. Once I found out that "Lopho" was Latin for "crest" and not "bony crest" I'm not sure if I should change them back to only having a crest of feathers.

But then again, they DO have a crest of bone and not keratin and it is for a fantasy story. I mean, rapters don't have talons or thumbs either which all do in my story.

My T. rex has a bit of a horn on it's snout: [link] I always figured the rough surface must have been for something.

I see reconstructions like yours a lot, giving T. rex a subtle arch to its snout. I'm thinking a bit more extreme than that, though. Nevertheless, you definitely have the right idea.

Great to hear :) i think a guanlong or proceratosaurs like crest would be in order.
