Nobody Signed. *The platinum spike at the boundary is real and both sides accept it. A 2.4-metre core that would narrow what it means has been frozen at minus twenty since November 2019, waiting on clause 7.* A 2.4-metre sediment core sits in a chest freezer in a university basement in South Carolina, at minus twenty degrees, logged monthly. It has been there since November 2019. Two laboratories agreed to split it. Neither has touched it. ## What both sides already agree on The platinum anomaly at the Younger Dryas boundary is real. It has replicated. Nobody in this argument disputes the measurement, and this newspaper has checked that in writing with both principals. What they dispute is what put it there: an extraterrestrial impact at about 12,800 years before present, or an ordinary terrestrial process — volcanism, or the slow concentration of a background dust signal by a boundary that is itself partly a gap in the record. That is the most argued question in Pleistocene archaeology, and it has a physical answer. Split one core lengthwise, run both halves blind, tie both to a single agreed age model, and the halves either agree or they do not. ## The handshake On 14 November 2019, at a conference in Bern, two directors who have spent a decade contradicting each other in print agreed to do exactly that. Both described the conversation to us independently. Neither disputes a word of the other's account, which is the only thing in this file both of them have ever said about the same event. Dr. Solveig Marek-Abiodun's laboratory would take the platinum and iridium. Prof. Hartmut Csendes-Oyelaran's group would take the shock-metamorphic and magnetic fraction. The age model would be built by a third laboratory that has published against both of them. On paper it is the best-designed experiment in the field. > **Figure:** Six years and eight months of a two-page document — see https://theyburied.com/article/brief-younger-dryas-unsigned-core ## Clause 7 This newspaper obtained the draft material transfer agreement and its covering emails, supplied by one party with the other party's written knowledge. Every passage quoted here was put to both principals first. There are eleven drafts. Three law firms have been instructed. The scientific annex — sampling plan, blinding, analytical order — has not been materially altered since draft two, in March 2020. Clause 7 has been rewritten nine times. It covers the residue. Which institution may publish on what remains of the core after the analysis, and which institution indemnifies which for the loss of a sample that the analysis consumes and that cannot be taken again. There is no villain in the file. It is two research offices doing their jobs correctly, on a thing that exists once. > You do not run a one-shot destructive experiment on a handshake. > > — Prof. Hartmut Csendes-Oyelaran ## The freezer Our correspondent was shown it on 16 June. A commercial chest unit with a padlock and a clipboard on the lid. Eighty-one monthly entries in four different hands. The temperature has never been recorded above minus 18.4. The core is in six sealed lengths, wrapped, on the bottom shelf, under a box of somebody's 2014 lake sediments. The technician who keeps the log has worked in that building since 2017. Asked what happens if the freezer fails, she said the alarm goes to her telephone, she lives eleven minutes away, and she has driven in twice. ## What this desk takes from it The argument has run in the literature for nineteen years and has produced, by our count, more than four hundred papers. The object that would narrow it is 2.4 metres long, is under a box of lake mud, and is waiting on two pages about who gets the leftovers. Professor Csendes-Oyelaran's reply, printed below, says we have made a careful problem look like a farce, and that the real obstruction is not the lawyers but an age model nobody has agreed. He may be right. We asked both principals, in writing, what result would change their mind. Neither answered, and both were shown that sentence before it printed. ## Sources (invented) - The draft material transfer agreement, eleven versions, with covering emails, Provided to this newspaper by one party with the other party's written knowledge — Read entire; both principals were shown every passage quoted here before publication and neither disputed the quotation (July 2026) - Dr. Solveig Marek-Abiodun, Directs the laboratory that would run the platinum and iridium fraction — Interviewed by video call twice, then by telephone with the drafts open (June–July 2026) - Prof. Hartmut Csendes-Oyelaran, Directs the group that would run the shock-metamorphic and magnetic fraction — Interviewed in person; read the full draft of this story and replied at length (June–August 2026) - The freezer log, Eighty-one monthly temperature entries, 2019–2026 — Photographed in the basement by our correspondent, with the technician present (16 June 2026) - A research contracts officer, At a third university, with no involvement in this dispute — Interviewed on the record about why clause 7 is ordinary (July 2026) ## What we could not confirm - Which side is holding it up. Each principal told us the other is. The eleven drafts carry edits from three law firms and no attribution on the last round, and the covering emails for draft eleven are between two research offices, neither of which replied to us. - Whether the core would narrow anything. Both principals say it would. We asked each of them in writing to state, in advance, what result would change their mind. Neither answered that question, and both saw this sentence before publication. - Whether the material is still fit to run. One laboratory says six years and eight months at minus twenty is immaterial. The other says the top forty centimetres may have to be discarded. They are the same two laboratories, disagreeing about the same core, which is the shape of this entire subject. ## Right of reply **Prof. Hartmut Csendes-Oyelaran** (Replied on 12 August 2026. Printed in full and unedited.): > I have read your piece twice and I will help you with the facts, all of which are correct, and then tell you what I think you have done with them. > > The facts. We agreed in Bern. We meant it. We still mean it. There are eleven drafts and I have read every one. Clause 7 has been rewritten roughly nine times, though I would say eight, depending on whether you count a version in which it was deleted. The core is in that freezer and I have stood in front of it. > > Now. Your headline says nobody signed, as though signing were the easy part and we are two children refusing to shake hands. Let me tell you what you are asking us to sign. > > The analysis destroys the sample. Not damages — destroys. There is no second run, no re-examination in 2044 with a better instrument, no possibility of a third party checking our work on the same material. When those six lengths come out of that freezer, one of two things happens: the field gets an answer, or the field loses the only core anyone has agreed on and gets nothing. You do not run a one-shot destructive experiment on a handshake. > > So yes, my institution wants to know who may publish on the residue, because in nine of the last twelve collaborations I have been part of, the fight came afterwards and it came about exactly that. And yes, somebody's lawyer wants an indemnity, because a unique sample has a value and a university that consumes another university's unique sample under an unwritten understanding is a university that will be having a different kind of conversation in five years. These are not obstructions. They are the ordinary furniture of doing careful work with someone you disagree with, and your own contracts officer told you so, and you printed it in a source note where nobody will read it. > > What I object to is the shape. You have taken a genuine institutional failure — six years is far too long, I accept that entirely and I am one of the people it belongs to — and you have made it comic. A freezer. A clipboard. A box of lake mud on top. Very good, very vivid, and it teaches your reader that the people arguing about the Younger Dryas are absurd, when what is actually true is that they are being careful about the one thing that cannot be replaced. > > One last thing, and it is the thing I would most like printed. You asked both of us what result would change our mind and you have recorded that neither of us answered. That is fair, and it is the sharpest paragraph in your story. My answer is that I do not know yet, because the age model is not agreed, and until it is agreed I cannot tell you what a disagreement between the two halves would even mean. That is not evasion. That is the actual problem, and it is not on page two of any contract. --- They Buried is a satirical newspaper. Every story, source, document and person in it is invented.
