Peltopleurids are also neat for having one of the earliest gonopodium examples in a ray-finned fish. This is a modified anal fin in an inferred male individual, by Lombardo (1999).

Peltopleurids and haplolepids. Divided by a gulf of time, united by a love for the game. Actually a wild case of convergence. Haplolepids are a Carboniferous clade known almost exclusively from coal-swamps, while peltopleurids are Triassic fishes known from marine environments.

#SundayFishSketch 🐠🐟And the series is now complete! Here is a selection of 21 pycnodont fish, showing their diversity through time Species in the Alt text #paleoart

Went through the storage of my predecessor in zoology at Bowie State. I now have 1) a very nice cart, 2) hundreds of excellent specimens for teaching (including fossils!), and 3) TWO bone saws.

I published a re-description of a long nose fish on the same day the famous Spinosaurus re-description came out.

Sounds like charity but I would quickly go mad with power and devote an entire exhibit hall to my personal research gripes, beginning with Spinosaurus.

question for the audience: if you were ultra rich (let’s say $25M), what completely frivolous thing are you buying?

Reminds me of the Jurassic Park book where you learn John Hammond is really good at getting people to give him money but does not understand the implications or danger of the technology he let loose on the world.

Prof Susie Maidment@tweetisaurus.bsky.social

Yes. As a consequence, we seem to be headed back to the bad old days of dinosaur taxonomy, where every isolated scrap gets a name. This is causing a vast proliferation of genera based on indeterminate and fragmentary material that overwhelmes phylogenetic analyses with missing data (1/2)

Porifera stays winning

TW Spider: Spider friends! I need your help. Can anyone ID this spider for me? Students and I found a dozen today eating spotted lanternflies. @forthespiders.bsky.social

I think we need a name for something worse than a wastebasket taxon. Perhaps for a taxonomic name that causes more problems as it careens around datasets, a “dumpster fire taxon” if you will

Jack Stack@jackstack.bsky.social

Side note but one of my goals is to have a hypothesis with a cool name. “Red Queen”, “Elvis taxa”, why do we let the invert people get all the cool ones?

Being a scientist is thinking you have a brilliant original idea and then seeing someone had the exact same idea in the 80's.

We acknowledge that we took this land but have no intention of giving any of it back, even when the Supreme Court tells us to.

I have lots of great taxonomic ideas. Turtles, for example, are potentially thyreophoran dinosaurs (shield-bearing). I would also argue that Spinosaurus could be classified as a Gharial.

My bid will be abolishing lungfish and rolling them back into onychodontiformes

Should students be exposed to such dangerous materials as Paleozoic ray-finned fishes?

Matt Friedman@friedmanlab.bsky.social

Teaching on campus, so no collections visit. Instead enjoy some actinopterygians for today's lab for EARTH 437: Vertebrate Paleontology.

I'll never forget being told as a kid that the Detroit Zoo might shut down because of the city debt. We have a crisis in management that sees collections as real estate or potential auction items rather than crucial pieces of our shared natural heritage that need to be protected.

Prosanta Chakrabarty@prosanta.bsky.social

Remember 'the Grand Bargain' for the Detroit Institute of Arts. They were nearly forced to auction off paintings to pay off city debt. www.nytimes.com/2014/11/08/a... Museums should not be held hostage because of the mismanagement and malfeasance of others.

Natural history museums are at an inflection point that started with the auctioning of dinosaurs. If Fort Hays State (Sternberg) or Drexel (Acad.Nat.Sci.) think they can monetize collections (i.e., sell natural history specimens); museums become safety deposit boxes instead of research institutes.

Introducing Herugavialis cairensis. A new genus of fossil gavialoid crocodylian from the Middle Eocene of Egypt. Recovered from the Mokattam Formation, Herugavialis was found from the same rocks used to build the Great Sphinx and pyramids of Egypt. Read here: doi.org/10.1098/rsos...

One of my students put a date into a survey form incorrectly, unless they surveyed a building for spotted lanternflies on February fourth, 2006.

Liz did a great job, I was extremely impressed with her ability to bring an animal known from objectively poorly preserved fossils to life.

My first scientific illustration featured in a publication! Congrats to Jack on the new paper, it was a pleasure working with you to reconstruct this impressive fish.
