I think this is a perfect transition into what I wanted to talk to you about today, which is how do we know the things that we know about dinosaurs?
And so I thought maybe we could start sort of where the paleontologists first started, which is the skeletons that they left behind.
So talk to me about how we sort of take a dinosaur skeleton, like a bunch of bones, and turn that into a story about reptiles running through the world.
Wait, wait, wait, wait.
Mm-hmm.
This dinosaur.
We have like these parts, like the front legs, some of its neck.
And what else?
How do we make something like this from some forelimbs, some vertebrae, some other bones, and a dream?
So you're showing me right now a model you have of a beautiful long-necked dinosaur with a long curving tail, four lovely long legs, red and green coloring.
Giant giraffe.
Big giraffe.
What are some of the most interesting or maybe even counterintuitive ways that we have been able to say, no, I'm pretty sure this looked this way, just by looking at the bones alone?
So I'm looking at, just to be clear, sort of what looks like two fingers of a T-Rex hand that have very pointy claws on the end of them.
Okay, so this tiny little bone, this bone that's actually the size of my pinky, is like an ancestral third finger, like a tailbone of a third finger that they have.
Fascinating.
Okay.
So finding bones, finding more bones to complete out a skeleton can really tell us, like, oh, we got this wrong, we got this wrong, et cetera.
But you also had an article that you wrote that was also about tiny arms that was a little different that I loved.
Can you tell me a little bit about Alvarezsaurus?
