Curious about Devonian actinopterygian lower jaws? Look no further--our new paper provides comprehensive descriptions for 19 species in a tidy ~50 page summary! anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Devonian ray-finned fishes were not particularly species rich, particularly compared to their lobe-finned cousins. This implies early actinopts might've also been anatomically monotonous. But a deep dive into their jaw anatomy w/ µCT reveals subtle but important structural diversity.

Our new paper on the historical and scientific basis of Darwin’s ‘coral reef paradox’ is out @currentbiology.bsky.social! Summary below by @gobyone.bsky.social. Also with @paulinenarvaez.bsky.social @oclaripv.bsky.social and Vale Parravicini! Free-access link: authors.elsevier.com/a/1lDFm3QW8S...

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️... Turns out that 2/3 of these assertions are very wrong... 🌐 🦑🧪 🧵⬇️

When thinking of the 'model' planktivore on reefs, fusiliers come to mind - their fusiform bodies, forked caudal fins, and large eyes appear built for the job. But are these traits common among most plankton-feeding reef fishes? 🐟 🔗 The story is more nuanced than we thought: doi.org/10.1007/s111...

Ever since Charles Darwin, scientists have assumed species facing the same problem often evolve similar traits. But that’s not always the case.
