New in @science.org, meet Acronichthys maccagnoi, a new species from Late Creatacous Canada that changes what we know about the origins and evolution of one of the most successful fish groups on Earth.

Excellent! Can you post link to paper again - can’t seem to get it to work.

Poacher head from the top - CT scanned by Dan Geldof.

I’ve had an MRI, CT, and PET scan this month.

MRI was loud. CT prep was gross. PET prep included radioactive ☢️ dye.

Now I know how the poor fishes @danielgeldof.bsky.social scan feel:good thing they are long dead. Dan will be defending his thesis on CT scanning Agonids next month! He is a wiz!

Awesome that you did this. Good on you.

Check out our new paper in Nature describing trends in US freshwater fish biodiversity! Great to be part of such an amazing team.

Another great anatomical innovation brought to you by your fishy ancestors …

There were perhaps too many parallels between me and the author of ‘The Last Lecture’ - 3 kids, 46 years old, cancer ♋️ … but maybe the most important is being thankful for living out your childhood dreams and for the people you have in your life.

Do Fish Pee? Yes, fish pee just like humans. Learn more on how fish regulate their bodily fluids.

“We evolved from fishes. We do what we do, including breathing through lungs, having nostrils that fill those lungs, having arms and legs, and big brains, all of which came from our aquatic ancestors. So did kidneys, lungs, and being able to pee!”— @prosanta.bsky.social

This Deep-Sea Fish Has Teeth on Its Forehead—and It Uses Them for Sex Researchers suggest the rows of pointed structures on the heads of spotted ratfish are true teeth, offering the first known example of teeth located outside the jaw

You got to write his NYT obit!

I knew you would like that Shaena - part of the story I didn’t say above is that Ward Wheeler said Mark would sign anything … so I went to the gift shop and picked this up specifically for that - I was going to get Novacek to sign the other side to complete the ‘Norellacek’ joke - but never got it.

Loved this book. Gives one a sense that human progress in understanding the living world is so embedded in culture. Perhaps we’re on the eve of a Buffonian Renaissance.

Cover of ‘every living thing’ with various organisms shown like the platypus giraffe and hydra

Just finished the excellent ‘Every Living Thing’ that focuses on the taxonomic battle and lives of Carl Linnaeus and the Comte de Buffon. The former gave us Systema Naturae and the binomial system we use for classification; the later gave us Histoire Naturelle which anticipated evolutionary theory.

Sad to hear about the passing of the great paleontologist Mark Norell - who I knew during my postdoc at the American Museum of Natural History. I once asked him to sign this mammoth 🦣 tooth because we both thought it would be funny. It is still funny but a little less so with his passing. RIP Mark.

Fun fish tank at my doctors office with South American cichlids and Asian rainbow fish among other critters from around the world.

Who is this cat @ichthyangela.bsky.social ?

Had fun giving a Museum tour to a graduate class in geology explaining the ways biology can inform geology from DNA-based phylogenetic trees being used to estimate the separation of landmasses (freshwater fishes are great for this) to looking at living species to help us understand extinct forms.

Fantastic! Thanks for clarifying y’all
