I know but where else would I turn to?
Carnivora forum seems to ask similar questions.

ok here is dual question:
1. how many prehistoric jaguars are there and where did they live?
2. how different were they compared to the modern day jag?

The closest things we have to a "prehistoric jaguar" are the European jaguar (Panthera gombaszoegensis) and the Pleistocene South American and North American jaguar (Panthera onca mesembrina and Panthera onca augusta respectively). The European jaguar is estimated to be about 70-210 kg and were built much larger as they were thought to have primarily hunted large game. The other two were very similar to a modern day jaguar.

so hypothetically speaking, how would a north american jag take on a human from 14,000 years ago?

Most likely the same way a modern big cat would hunt a human, you can easily find information about that through sites like Wikipedia. As for the human fighting the cat, they'd most likely be using spears and an atlatl.

Jaguars are unusual in that they prefer to bite the back of their prey's skull over strangulation.

If I was to provide examples of feathers in the Coelosaurians what would be some examples that an audience would recognize (and this particular audience has only the basic understanding of dinosaurs and the different species)

T. rex should be pretty easy IMO. It has an instantly familiar shape to the majority of people, with or without feathers.

See that's the thing, I'm giving a speech incoming people about Trex having feathers and I need some other members in the family that had it...my first examples are Velociraptor and Archeopteryx

Could try with Onrithomimids, people might not know the exact genus but a lot are familiar with the ostrich-like dinos.
Therizinosaurs and Oviraptorid seem a bit hardcore for a general audience.

Or you could introduce them to some new, much more closely related creatures such as Yutyrannus and Dilong.

Think I'll say Gallimimus just for the sake that it was introduced widely in Jurassic Oark and everyone has seen it :P

Never fret Dilong and Yutyrannus will be mentioned of course! Thank you for the suggestions everyone

Is it possible for something like Allosaurus to have its crest covered in keratinous material, something similar to hornbill's casque?

Based off the texture of the skull bones, it seems to me that Allosaurus would have had a pair of keratinous ridges running along the snout, but the crests themselves, along with the areas surrounding the eye, were covered in thickened hide instead.

I'm not 100% on it though since it's hard to tell via online pics whether you're looking at scarred bone (which would mean thickened hide), or genuine pores (which would indicate blood vessels, and therefore keratin).
