Back to the Thursday collection routine after a chaotic few weeks. Today, some visiting researchers were studying this phytosaur and metoposaur material collected by E. C. Case in UMMP's early days.

Ray-finned fishes are famously diverse, but we know little about their brains or cranial endocasts. @rodrigoichthys.bsky.social opens this black box with a dice-CT survey of 86 species across the actinopt tree of life. #OA in @royalsocietypublishing.org 🐟🧠 royalsocietypublishing.org/rspb/article...
Figure of radial phylogeny featuring colored branches and tips representing brain-to-endocranial cavity correlation and endocast complexity. Select endocasts (rendered as semitransparent gray) and brains (rendered in peach) are shown for some terminals. They show substantial variation in shape and the degree of brain:endocast correspondence.

Last night, it was my honor to deliver the inaugural "Spoonful of Knowledge" lecture for the U-M Cereal Club. I gave an updated version of a talk on cereal mascot evolution put together in the last year of my PhD, longer ago than I care to admit. Poster credit: Cereal Club Instagram.
Poster for a spoof academic lecture. Title reads "The Macroevolution of Cereal Mascots: A lecture by Dr. Matt Friedman." Cropped circles show pictures of Darwin and Matt; these flank the title. Below, a variety of colorful cereal mascots are shown, with a quote from Origin: ". . . endless forms most beautiful have been, and are being, evolved." The time and venue is listed at the bottom of the poster: Thursday, April 9th, 8:30 pm Biological Science Building.Poster for spoof academic talk. Several lines of text are shown against a cream background:

8:30PM THURSDAY, APRIL 9TH

A SPOONFUL OF KNOWLEDGE

RM 1010 BSB

World-reknown paleontologist, Dr. Matt Friedman, will be giving an exclusive lecture on the macroevolution of cereal mascots. If you don't know what that is, you should come. If you already know what that is, you should still come.

We will be providing cereal, milk, bowls, and spoons as usual, but byob, byom, byoc, and byos is encouraged!

Two images are shown at the bottom of the poster. The first is a cartoon-like illustration of a stack of books topped with a bowl of cereal bearing the Cereal Club logo. The second shows the classic illustrated sequence of human evolution, with the modern human's face topped with the Cereal Club logo.

🚨Research alert! Two new studies, led by Museum scientists, suggest that biofluorescence in fish dates back ~112 million years & has evolved independently 100+ times, with the majority of that activity happening among species that live on coral reefs. Learn more ⬇️ amnh.link/4nlyBrk

Here's a stunner for #FossilFriday, just look at that beetle's preserved wing case! It belongs to a group called frog-legged leaf beetles (so-named for their extra-juicy rear legs), paleontologists called its pattern "the most perfectly preserved pigment-based colouration known in fossil beetles" 🧪

49 million-year-old beetle looks like it was squashed yesterday
Paleontologists named the insect "Attenborough's Beauty," after Sir David Attenborough.
