Questions in this episode:

• Did Spinosaurus hunt by swimming like a crocodile, or stalking prey like a heron?
• If you could discover one fossil that would revolutionise our understanding of spinosaurs, what would it be?
• Is the famous Coelophysis cannibalism evidence still accepted?
• If fossils become rock, how can scientists still use chemical isotopes and other geochemical clues to study them?
• What is the one fossil each of you would most like to discover?
• Are the waffle-textured Stegosaurus plates shown in Netflix's Life on Our Planet scientifically plausible?
• If you could visit any point in prehistory, where would you go? Has there been any progress understanding the enormous vertebrae from Zhuchengtyrannus?
• How has recognising Nanotyrannus as a separate species affected our understanding of Tyrannosaurus growth?
• What do you think about the recent paper on T. rex parental care?
• Is there any evidence that spinosaurs fought each other or other dinosaurs?
• Do we have any evidence that different dinosaur species hybridised?
• Did tyrannosaurs hunt in family groups or packs?
• Following the record-breaking sale of Gus, should fossils be protected by laws similar to archaeological treasure?
• Could high-quality 3D printing help solve the problems surrounding private fossil ownership?
• What's the current thinking on the famous sail of Ouranosaurus?
• Did pterosaurs tear their wings, and if they did, could they still fly?
• What do the newly described sensitive snouts of spinosaurs tell us, and what do Dave and Iszi think about the latest debate over Suchomimus and Cristatusaurus?

Plus, Dave reveals the fossil he'd most love to discover, Iszi campaigns for giant prehistoric frogs, and the audience helps bring the episode to a suitably noisy dinosaur conclusion.

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?
