New profile, so here’s an intro post! I’m a paleontology student trying to figure out what fossil shrews were eating. It turns out the fossil record of shrews is full of oddballs, so I’m looking at their modern diversity to inform what fossil forms might have been doing. Shrew related antics ensue!

Consoravis further reinforces how connected European and North American avifaunas were during the early Eocene, and adds additional data to help clarify the origins of passerines

These critters all lived in the first six million years of the Cenozoic and each one was, in its time, the biggest mammal that had ever existed.
It took some work to balance the intended message, desired visual impact, and tech limitations, but I think the latest version of this display works well.

Part 2 of Life Over Time’s last day: the dinosaur hall. You’ll have to imagine the sauropod stomping sounds and the Parasaurolophus tuba noises that were a constant part of this space.

I'm delighted to have gotten ahold of some footage of Life Over Time's last day (May 3, 2004)! This was kindly shared by Dave Dolak, who used to show it in his classes at Columbia College.
I've cut the video into three parts for easier viewing, starting with the Paleozoic:

Apparently Bill Simpson, longtime Collections Manager of fossil vertebrates at the @FieldMuseum in Chicago, is retiring—after 46 yrs! Bill has always been so helpful, including pulling out the skull of @SUEtheTrex for study multiple times! Happy Retirement, Bill! 🎥: Emily Rieff #FossilFriday

Super cool stuff!! Tess has put a massive amount of work into this project, and the end result is really incredible. Certainly worth a read, and major congrats to @tessasaurus.bsky.social and the rest of the team!

While the paper hasn't come out just yet, the news certainly has. Proud to announce our discovery of color patterning in a sauropod dinosaur. Will go in depth tomorrow.

Hey Ben,
The museum is its own separately funded unit, so while this hurts, and directly affects our curators and interns from EAS, UNSM including Ashfall and Trailside remains open and active.
That said, we are gutted. EAS have been allies and partners with the museum for a hundred years. No more.
