cartilage rings give support to trachea to open all the time
Cartilage is a softer structure that is generally not fossilised, but it can in fact be found on some fossils. I dug around for some info, and found that a mosasaur was found with at least some of its cartilage fossilised. I'm sorry I can't give more information, I've been looking for a solid answer myself, looking for proof of our ancestor's nose shapes. There's not much out there for whatever reason.
The cartilage rings in the throat prevent the trachea from collapsing.

Cartilage
The shape of the jaw comes from a bine called the Mandible. The shape of the nose comes from cartilage that projects from tha Nasal Bone (shapes only the very top part of the nos) and the Maxilla.
Cartilage is a tough, flexible tissue found in the human body, such as in the ears and nose. An example sentence could be: "The cartilage in his knee helped cushion the impact of running on hard surfaces."
