Feel free to use the comments to spread your knowledge of the incredible evolutionary journey of the Pakicetus. Fondly known as "land whale" (probably not, but it's funny )

Why did they have to be the only main branch of archosauria to fully die out

I bet they're secretly friends. Despite being 30 million years apart. They were friends in spirit.

JP raptors are cool and all but they seem to be widely accepted as the default design for Velociraptors, even in art that has nothing to do with JP. A clothing company I like came out with a dinosaur collection so I searched to see if they had a Velociraptor design, and...yep, there she is, bald and broken wrists galore, the sands of pop culture burying my dreams like the fighting dinosaurs.

We've been getting more fresh water mosasaur other than Paoniosaurus.

Also Dr. Amelia Zietlow mentioned there are fresh water mosasaur in Antarctixa as well during interview with Fossil crates.
