Teeth.

It's not all teeth.
With birds it's all beaks.
With birds it’s all beaks.
That's only for the last 100 million years. Before that it's all teeth too.
Birds had teeth 100 million years ago, then suddenly they didn't?
Here is an excellent video that explains why the non-beaked birds died out: https://www.youtube.com/watch?v=M1TanPmCckM
Teeth?
Say more! Genuinely curious about this
Makes me think of this: https://en.wikipedia.org/wiki/Dentition#Dental_formula
Teeth can tell you a lot about an animal. Their size, shape, number etc can tell you what it eats or how it eats or how much it eats. Dental formula can give you clues for how animals are related to each other. If two different animals have the same dental formula then maybe they share a common ancestor or have a similar diet. If two animals are already very similar but have different dental formula then maybe they're only very distantly related or there's been some convergent evolution elsewhere.
It's still the best way of identifying animals and human bodies thank you very much. This is why 1/10 conspiratorial privacy advocates advise against going to the dentist. That's Gary. He's kookoo for cocoapuffs and also has really bad teeth.
