In this bite from an old live stream, Iszi Lawrence and Dr Dave Hone discuss why claims of the "largest dinosaur ever" are much harder to prove than the headlines suggest. They explore how palaeontologists estimate the size of enormous titanosaurs, why complete skeletons are so rare, and why finding an even bigger individual is always a possibility.

Along the way they also discuss whether dinosaurs ever stopped growing, why weight matters more than length when comparing giant animals, and why every new "biggest dinosaur" announcement should be treated with a healthy dose of scientific scepticism.

Should dinosaur fossils belong in museums—or can they be bought and sold like works of art?

When the spectacular Tyrannosaurus rex known as "Gus" was preparing to go under the hammer (and has since sold for a staggering $50 million), it reignited one of palaeontology's biggest ethical debates.

In this episode Dr Dave Hone and Iszi Lawrence explore the booming fossil market and ask what happens when scientifically important specimens disappear into private collections. Is it wrong for billionaires to own dinosaurs? Can privately owned fossils still contribute to science? And why won't many scientific journals publish research based on privately owned specimens?

Dave draws on his own experience working with museums, private collectors and commercial fossil dealers to explain the surprisingly complicated relationship between science, money and ownership. We discuss museums, fossil laws, famous auction sales, and why a dinosaur's scientific value isn't always the same as its auction price.

Questions covered in this episode:

• Should dinosaur fossils be sold at auction?
• Why won't scientists study many privately owned fossils?
• Is it ethical for billionaires to own dinosaur skeletons?
• How do fossil auctions affect palaeontology?
• Could private ownership ever benefit science?
• Why are some fossils worth tens of millions of dollars?

🦖 Harry (age 8) asks:

• We saw Titus the T. rex and the supposed bite mark on its tail — is it really a bite, and what other pathologies does Titus have?

🎨 Phil asks:

• What does Dave think of the life-size Spinosaurus model unveiled in Germany?

🏛️ Listener question:

• Is there a clade-specific or thematic dinosaur exhibition we would love to create or contribute to?

⭐ Listener question:

• Which dinosaur has the potential to become the next major superstar in the way Velociraptor and Spinosaurus did?

Along the way, Dave explains why consultants don't always agree with every detail in a museum display, discusses the challenges of interpreting fossil injuries, and reveals his dream of creating a Dromaeosaur or Pterosaur exhibition.
