2/6 Bowfins are one of North America's ancient ray finned fish clades. You might remember that in Nov. 2022, myself, @DaeminKim3 @TJNear @SolomonRDavid and colleagues named a second living species from this 250 million year old lineage: Amia ocellicauda. Photo: JM Mollish
1/6 ⏰⏰ New publication with @TJNear in @ZoolJLinnSoc ! We describe a big new fish from 10 million years after the impact that killed the dinosaurs. Introducing †Amia basiloides, or, as we've nicknamed it, the big a** bowfin! doi.org/10.1093/zoolin… #fossils #paleontology
Sharks!!?? Nope! LAKE STURGEON spawning below a dam in Wisconsin! FINtastic video of these living fossils from @AmyMCottrell! 📹Amy Cottrell (with permission)

On Australia’s east coast, scientists from @GriffithARI and @qldscience have confirmed the identity of a cryptic #Endangered #lamprey species 1400 km north of its previous known range - this is the first truly tropical lamprey in the world! 🐟. bit.ly/esr_53_547

Bowfishers: This could have an impact on more than just Minnesota if they are able to change rough fish to native rough fish. Me & Native Fish Conservation Folks: Um YES, let’s hope so!!! Check the comments: instagram.com/p/C58mb-ysL5W/… 👍
For this week's #SundayFishSketch I chose to focus on how far-reaching plastic pollution is and drew a snailfish swimming past a plastic bag at the bottom of the Mariana Trench

But it now represented by just two species. Do you have thoughts on the causes of their quite recent decline?
@AndrejSpiridon4 @ChaseBrownstein @ZoolJLinnSoc I have no speculation on decline of bowfins, but intriguing that they survive in a part of the world that contains many other ancient lineages of freshwater fishes. The Eastern North American Freshwater Museum...
6/6 As always, thanks to @TJNear & @yalepeabody. A big shoutout too to @Friedman_Lab & @DiggingDinos for helpful discussion about this critter!
5/6 Perhaps the coolest thing about it is that the new species establishes parallel episodes of substantial body size increases in different bowfin lineages that appeared on both sides of the K-Pg boundary in western North America! Two dynasties of giant bowfin!
4/6 Amia basiloides is the biggest bowfin and the oldest named species of Amia (the genus that includes the living bowfins). It helps illuminate big amiids, which have been known from scant fossils in North America for a while, as giant members of Paleogene freshwater faunas.
3/6 In 2021 when I was doing the osteological research for that paper, I found a giant bowfin fossil from the Paleocene of Montana in the @yalepeabody collection. It's a complete skull and most of the skeleton. So we CT-scanned it!
2/6 Bowfins are one of North America's ancient ray finned fish clades. You might remember that in Nov. 2022, myself, @DaeminKim3 @TJNear @SolomonRDavid and colleagues named a second living species from this 250 million year old lineage: Amia ocellicauda. Photo: JM Mollish
1/6 ⏰⏰ New publication with @TJNear in @ZoolJLinnSoc ! We describe a big new fish from 10 million years after the impact that killed the dinosaurs. Introducing †Amia basiloides, or, as we've nicknamed it, the big a** bowfin! doi.org/10.1093/zoolin… #fossils #paleontology
