These have since been joined by beautifully preserved fossils from the Yucatan peninsula of Mexico that seem less "archaic" than the Swedish ones. Modern research dates to the last decade, but fossils from this site were first discovered in pre-contact times: www.sciencedirect.com/science/arti...

For #FossilFriday, fish tiles from the old fossil fish gallery at NHM, now the main gift shop: Pterichthyodes (Devonian placoderm), Holoptychius (Devonian sarcopterygian), Exellia (Eocene percomorph), and Polypterus (Recent).

metazooa when its a fucking passerine or percomorph again

From Antarctic eelpouts to African cichlids, the percomorph (literally “perch-like”) fishes have been a remarkable system for studying how genomic changes underpin evolution by natural selection 🐠🐟🧪

just fuckin learned that fish that look like this specifically are one of those weird modern era things the percomorph fish only really exploded into success after the asteroid hit. good times

Pisces Point previously yielded the percopsiform Lindoeichthys, then the oldest articulated freshwater acanthomorph from North America. To this, the authors add an articulated percomorph and (more intriguingly) a polymixiiform. Impressive use of CT on these small skeletons.

2/9 Using markers from across the genome, we show that the three lineages closest to Percomorpha, a clade which contains everything from basses to anglerfishes to tunas to gobies, are not informative for understanding the ecology of the ancestral percomorph.

Scientists found ~500 fish fossils in Egypt, 62 million years old, preserved perfectly, dating just 4M years after the asteroid that killed the dinosaurs

One family of survivors eventually became tuna, seahorses & 17,000+ species.
