Ooooh you want to check out these Lebanese prawns so bad!
Inspection page from the free virtual museum SHADOWBOX of a prawn fossil. Its scientific name is Carpopenaeus, and it was collected in Hjoula, Lebanon. It is of the Cenomanian Age of the Cretaceous Period, dating back to roughly 95 million years ago.

Looking forward to seeing familiar faces and meeting new people at this year's WAVP! My team is presenting on new developments in the Cretaceous-aged Menefee Fm. of New Mexico... I'm speaking at 9:45am on Saturday, sharing the very first report of coprolites (that's fossil poop!) from this unit.
Title slide for a conference talk: First Report of Coprolites from the Upper Cretaceous Menefee Formation, New Mexico, USA. Image at the center of the slide shows a turd-shaped fossil the size and shape of a baby carrot.

In addition, I've download 104 of those files for posterity from the DOJ website and zipped them. I also curated a Zotero collection of these files, with links to the DOJ pages I downloaded them from. Both are available for anyone who would like; DM me an email address and I'll send them over.

You can read my breakdown of the Horner - Epstein contact timeline starting with this comment: www.reddit.com/r/Paleontolo... You can read a shorter summary of my conclusions here: www.reddit.com/r/Paleontolo... Screenshot of the short summary below.
Conclusions: 1. Horner and Epstein had repeated direct and indirect contact throughout 2012. Horner initiated contact again in 2016. Unclear which man first initiated contact and the extent to their communication not revealed in current DOJ releases. Reminder: Epstein was first convicted of attempting to hire a minor for sex in 2008. 

2. Horner visited Epstein's Zorro Ranch in New Mexico on the weekend of August 3rd, 2012, to fossil hunt alongside Epstein and Danny Hillis. We have his exact flight numbers and departure/landing times. This was originally set for late July, but Epstein's scheduling issues with Woody Allen bumped the Ranch event by several days.

3. Afterwards, Horner solicited Epstein for funds to host a Dinochicken project conference at MSU from October 24-25 of that year. It is confirmed that Epstein cut a check to make this happen.

4. Afterwards, Horner sends a thank you message to Epstein and offers to add him to a dropbox of conference videos and photos, but mentions that this will make Epstein's name and email publicly visible, and asks Epstein if he has another email that is "less conspicuous".

5. In his correspondence with Epstein, Horner repeatedly mentions "the girls" to whom he offers best wishes, and calls Epstein someone "whom I envy".

6. Horner attempted to return to Zorro Ranch with a student in September of 2016, and it is unclear whether this took place. No emails more recent than 9/2016 mentioning Horner are publicly available from the DOJ.

7. An exchange between Epstein and Ghislaine Maxwell in August of 2012 confirms that the two of them, alongside Bobby Kennedy, went looking for fossils with Horner during a previous, separate trip to North Dakota.

There is no man, no scientist, no legacy that is so important that they cannot face consequences for their actions. There is no research that is so important that it must be carried out, even if it can only be done with funding from wealthy pedophiles. Rescind Horner's Romer-Simpson medal. Ban him

Founders of modern paleontology, and their contributions to systemic racism, classism and sexism (🧵) Henry Osborn (1857–1935), responsible for naming of Tyrannosaurus & Velociraptor; president of ANHM. Co-founder of the American Eugenics Society. Contributing to books later praised by Hitler.

(11) In 2013, Horner was awarded the Romer-Simpson Medal by the @societyofvertpaleo.bsky.social (its highest honor). I was at the meeting and saw his acceptance speech. Given this, I would urge those still in SVP to perhaps call on the Society to RESCIND the Medal and suspend his membership...

Nope, the date says this is after Epstein’s 2008 conviction in Florida. Funding is hard to come by, but there was no reason not to know Epstein was a problematic funding source in 2012.
