Jakapil is a great example of this. It brought a whole new family of ornithiscians to light, and it being a thyreophoran isn't even garuanteed. Teeth similar to it have been found in other formations (the kem kem beds for example), and alongside the fact jakapil has a lot of basal thyreophoran traits it could be an indicator that a whole ghost lineage has been hiding under our noses, just waiting to be found!

Which... We've actually recently figured out too, come to think of it. Well as figured as anything is... But as this show memorably taught me "pandas are like vegan gym bros" that eat the most protein packed parts of the plant throughout the year. I wonder both if that was the case for therizinosaurs, and if ppl in the future will find a panda bear fossil and be like "what is this?!"

While the turtle-themed species named may be off based on its initial speculation, at least the genus name still suits this unique dinosaur. It's hard to go wrong with calling something with massive claws a 'scythe lizard.' Although, could you imagine these guys cosplaying as the Ninja Turtles? And I do mean any incarnation.

When I was a kid in the early 90s, I was always struck by those big mystery claws.. and the weirdness of what were called "segnosaurs" at the time. Or the mystery giant "toe" claws of Megaraptor .. which ended up being hand claws. Or the other set of mystery claws that ended up being even weirder, Dinocheirus. It was sooo satisfying seeing the mysteries of those fossils solved. It turns out that Therizinasaurus, megaraptor, and dinocheirus were even weirder than kid me could have imagined. I'd love to see an episode on the Megaraptor. It's just as interesting as this or dinocheirus
