BEHOLD the GARgantuan Alligator Gar!!!
This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)!
A true river monster, among the largest caught, tagged and safely released! #GarWeek

New piece with @stuartsumida.bsky.social, Kristi Curry-Rogers, and Kenshu Shimada, and help from @magratnj.bsky.social : theconversation.com/fossils-are-...
Fossils are scientific evidence, and shouldn’t be auctioned for millions to private buyers
Dinosaur fossils are sold for millions to private collectors. These fossils are scientific evidence, and need to be accessible for research and public education.

Differential performance of aqueous‐ and ethylic‐Lugol's iodine stain to visualize anatomy in μCT‐scanned vertebrates
We compared the performance of two common diceCT scan stains, ethylic-Lugol's iodine solution with aqueous-Lugol's, across several vertebrate orders to assess differential imaging outcomes. We found ...

After years of work the Open Vertebrate TCN project ended last year. We were able to generate thousands of freely available zoological micro-CT scans for the research community. Check out the oVert paper here:

While UofMichigan has some sports newsworthiness, I’d like
to take this opportunity to remind everyone that the UM Museum of Zoology houses world’s largest fluid preserved snake collection, including an especially great collection of Thamnophis. #GoBlue 🐍

Once again, I compiled a list of all the new species described by museum scientists this year and the results are in: a staggering 815!!
Most of this was the work of two people describing an incredible number of parasitic wasps 🐝
