What are the key takeaways from this Odd Lots episode?

Key insights include: **Provenance documentation:** Buyers should require GPS coordinates at point of discovery, land deed proof of legal title, written agreements between landowner and fossil hunter, on-site witness statements, and ideally video footage of bones in situ before excavation is complete. This checklist, borrowed from antiquities dealing, protects against fraudulent title claims and undisclosed composites.; **Completeness assessment:** A bone map showing a bone as "present" can be misleading — a dealer may have only 5% of that bone. Buyers should commission conservators to document what percentage of each individual bone exists, and prioritize key anatomical features over total bone count. For a triceratops skull, intact horns matter more than frill completeness.; **Pre-buy strategy:** By the time a significant skeleton is fully excavated, prepped, and documented, it competes against sovereign wealth funds and auction houses. Serious collectors should establish relationships with dealers early, agree on acquisition criteria in advance, and commit capital before preparation begins — often from photographs taken during active excavation.

What did Salomon Aaron discuss on Odd Lots?

Salomon Aaron, director at London-based David Aaron gallery, explains the structure of the commercial dinosaur fossil market — covering provenance standards, pricing benchmarks, buyer demographics, the private-versus-museum debate, and how rising prices are directly funding new paleontological discoveries across Wyoming, Montana, and South Dakota.

Key Takeaways

✓Provenance documentation: Buyers should require GPS coordinates at point of discovery, land deed proof of legal title, written agreements between landowner and fossil hunter, on-site witness statements, and ideally video footage of bones in situ before excavation is complete. This checklist, borrowed from antiquities dealing, protects against fraudulent title claims and undisclosed composites.
✓Completeness assessment: A bone map showing a bone as "present" can be misleading — a dealer may have only 5% of that bone. Buyers should commission conservators to document what percentage of each individual bone exists, and prioritize key anatomical features over total bone count. For a triceratops skull, intact horns matter more than frill completeness.
✓Pre-buy strategy: By the time a significant skeleton is fully excavated, prepped, and documented, it competes against sovereign wealth funds and auction houses. Serious collectors should establish relationships with dealers early, agree on acquisition criteria in advance, and commit capital before preparation begins — often from photographs taken during active excavation.
✓Pricing inflection points: The 2020–2021 Christie's sale of the T. rex "Stan" for $31 million reset the entire market. Prior record was $8 million for "SUE" in the early 2000s. A complete triceratops skeleton called Big John sold for roughly $8 million around 2022–2023, against a prior category record below $1 million, illustrating how compressed the repricing timeline has been.
✓Private trade and science: Commercial fossil hunting funds discoveries that would not occur under academic budgets alone. Dealers can broker arrangements where private collectors acquire specimens specifically for museum loan or donation, with the Natural History Museum UK example showing a newly identified species secured for public research through a philanthropic buyer introduced by a commercial gallery.

Notable Moment

Aaron disclosed that sellers have occasionally withheld bones during a sale, then contacted buyers months later demanding additional payment to release the remaining pieces — a form of post-sale extortion that highlights how underdeveloped legal and contractual norms remain in this market.

Joe, when you were a kid or do your children now, are they into dinosaurs? Did you go through a dinosaur phase? Absolutely. I love dinosaurs as a kid. My kids are, of course, into dinosaurs. They're really into not only dinosaurs, but telling me which prehistoric animals aren't dinosaurs. So I'll Wait. Does this come up a lot in conversation? Yeah. Because I'm a troll to them. So I'll be like, what's your favorite No. So I'll be no. But I'll say things like, what's your favorite dinosaur? Mine's the pterodactyl. And then my daughter rolls her eyes like, dad, pterodactyl is not technically a dinosaur. Wait. Is that true? I do not know that. Yeah. Yeah. Wait. Explain. It's something I don't understand it. I apparently, it's like a it's just a it's not technically a dinosaur. It's a prehistoric animal of some different nature that is technically not a look it up. Alright. Well Look it up. Learn something new every day. I'm kind of you know what? I'm I'm gonna sound like a crank here. I'm not a flat earther, but I'm, like, sort of I'm skeptical of dinosaurs.
