• The crest is a mound of bone on the top of the head.

• The tip of the crest comes to a sharp point! Instead of the typical blunt end. 

• The rise of the crest begins at the nose and stops at the back of the head. 

• It may be considered knife-like, but should not come to a sharp point at the tip

• The crest can be curled upwards or downwards, and be tightly or loosely curled. 

This trait can appear as two distinct variations:

1. Feathers can replace the membrane of the crest, and/or cover the top of the crest with feathers.
   OR

2. Feathered Crest may completely replace the standard crest with feathers (reminiscent of a cockatoo's crest). 

• The crest may flare upward or stay static, but cannot completely disappear into the back of the head/neck when ‘flat’.

• The feathers should not extend past the default crest's length.

• The 2nd variant of feathered crest CAN NOT combine with other bone-based crests, and may have difficulties mimicking sounds. 

• The crest is a large bony plate that projects forward from the forehead. 

• The crest widens towards the tip like an axe or a fan, similar to an Olorotitan! 

• The crest splits off into 2 separate growths.

• May resemble certain dual-crested theropods like dilophosaurus, cryolophosaurus, allosaurus, etc.

• This crest is broad and flat, resembling a ceratopsian frill. 

• Can include spikes similar to those on ceratopsians.

• This crest is a long pointed plate, often resembling some (but not all) pterosaur crests. 

• A single, flat crest on the central line of the head with two distinct "points".

• Resemble the crests of lambeosaurs and some pterosaurs such as nyctosaurus.
