Contrasting evolution of the Arabian Sea and Pacific Ocean oxygen minimum zones during the Miocene - Communications Earth & Environment The Arabian Sea and eastern tropical Pacific oxygen minimum zones were better oxygenated during the warm Miocene, but with regional complexities, according to analysis of trace elements and nitro...

🚨New paper out with @alexauderset.bsky.social! We show that the Arabian Sea oxygen minimum zone (OMZ) was better oxygenated during the warm Miocene Climate Optimum than today, but its path to full deoxygenation was slow and complex.

When @omearabrian.bsky.social saw the manuscript, he described it as: ‘What if this figure could be an entire paper?’

I choose to interpret that as high praise.

Studies Reveal Fish Biofluorescence Dates Back 112 Million Years | AMNH Fish biofluorescence evolved more than 100 times, has ties to coral reefs, and involves more colors than previously thought.

🚨Research alert! Two new studies, led by Museum scientists, suggest that biofluorescence in fish dates back ~112 million years & has evolved independently 100+ times, with the majority of that activity happening among species that live on coral reefs. Learn more ⬇️ amnh.link/4nlyBrk

The history of the ocean, as told by tiny beautiful fossils Bountiful remains of foraminifera reveal how organisms responded to climate disturbances of the past. They can help predict the future, too.

It's been a pretty strange week.
I was interviewed a bit ago for an article about Foraminifera and a recent spate of papers.
Sadly, but predictably, @chrislowery.bsky.social got the best quote in.

Hey check out this new paper by former UT postdoc Katya Larina (plus former UT postdoc @foradamifera.bsky.social, @anshumans.bsky.social, @rowanmartindale.bsky.social, and Cori Meyers who I don’t think is here?) www.nature.com/articles/s41...

Fossil fishes from Holzmaden, preserved as black fossils on dark gray rock.

Fossil fishes (mostly) from Solnhofen, with brown fossils on cream colored rock.

Fossil fishes from Bolca, with dark brown fossils against gray to beige matrix.

In transit to #SICB2025 on #FossilFriday, but here are snapshots of three famous European marine Lagerstätten from a New Year's Day visit to USNM: Holzmaden (Early Jurassic), Solnhofen (Late Jurassic), Bolca (Eocene).

Hi! Can I be added?

I am looking for a PhD student to start in fall of 2025 at MSU. Potential topics include trait-based approaches to plankton community resilience, temperature effects on communities, harmful algal blooms and many others. Please get in touch if interested. More info: www.kl-lab.group.

Amazing fossil alert.

Hi Josh! Could you add me? I am an incoming curator at the museum of Paleontology at University of Michigan.

49 million-year-old beetle looks like it was squashed yesterday Paleontologists named the insect "Attenborough's Beauty," after Sir David Attenborough.

Here's a stunner for #FossilFriday, just look at that beetle's preserved wing case! It belongs to a group called frog-legged leaf beetles (so-named for their extra-juicy rear legs), paleontologists called its pattern "the most perfectly preserved pigment-based colouration known in fossil beetles" 🧪
